A Mobster’s Guide to Switching Baby Formula

There is a lot of confusion about the ins and outs of switching baby formula.

Sometimes, it really matters.  (As in: you’ll be up at 3am with a screaming baby matters.)

Sometimes, it really doesn’t.  (As in: you’re stressing over nothing.)

Actually, it’s really easy to figure out when you need to be careful, and when you don’t. All you have to do is think of your baby’s formula like he’s a mobster. 

Step One:
Determine the Formula Mob Family

A Formula Family is a group of formulas that are designed for a specific purpose or made with specific ingredients.

The first step to ensure your switching will go down like a boss is to determine the type of formula you’re using, and the type of formula you want to switch to.

If they are in the same family, you’re fine.  Switch away.  If they’re not…you’ve got a bit of work to do.

Here are the main “Formula Mob Families” you need to know.

Formula Mob Family #1: Bovine-Based

This formula family has the most members, because most of the standard baby formulas are based on cow’s milk (bovine = cow).

If your baby doesn’t have any health issues and is drinking formula, he’s most likely drinking a formula that is built around the cow’s milk dairy proteins.

So if you’re using Good Start and want to try switching to a baby formula like Similac, go for it.  Watch your baby carefully for signs of fussiness the first day, but generally the transition is pretty easy.

Formula Mob Family #2: Goat-Based

In the past few years, there’s been a huge uptick in the number of parents turning to goat’s milk formula.

  1. It tastes sweeter, more like breastmilk.
  2. Goat’s milk makes a smaller curd in the stomach, so is much easier for small tummies to digest, lowering incidents of constipation and gas.
  3. Studies like this one have shown goat’s milk is a good choice for children who struggle with eczema.

If your baby struggles with these things and you want to give goat’s milk formula a try, click here to try a free sample. The formula is sold as a toddler formula, but is appropriate for any child over 6 months who is also eating solid foods.

Formula Mob Family #3: Soy-Based

If your formula container says “soy” on it, you shouldn’t switch to another non-soy formula without going through the steps I’ve outlined below. I’ve listed the major brands of soy formula in my article How to Choose the Best Baby Formula for Your Superbaby.

Formula Mob Family #4: Low-Lactose

The formulas in this family are all partially broken down, and are usually sold under the names “Sensitive” or “Gentle”.  They are most commonly given to babies who are showing formula allergy symptoms.

Formula Mob Family #5: Hypoallergenic

These are the top-tier expensive formulas that are generally given to babies with severe allergies and colic.

They are completely lactose- free, and the proteins are so small that your baby only has to absorb them.  There is almost no digesting at all.  They are made so that ALL the proteins are already broken down.

Step Two:
Introduce the Families Slowly

The worst thing you can do for your baby’s tummy is to switch abruptly between the mobster formula families.  They don’t take kindly to having other families take over their territory, and tummy rebellion is common.

To avoid these feuds, set up a schedule for switching baby formula on a gradual basis.

  1. First Day: 75% old formula, 25% new formula
  2. Second Day: 50% old formula, 50% new formula
  3. Third Day: 75% new formula, 25% old formula
  4. Fourth Day: 100% new formula

Of course, if you want to take two days (or more) for each step, that is totally up to you. Choose the speed that you think your baby would be most comfortable with.

Step Three:
Watch Your Baby’s Reaction

The best sign that you’re baby is switching baby formula effectively, is to watch your baby like a hawk in the first 24 hours.

Specifically, watch for these things:

  • excessive gas (as in: more gas than normal)
  • constipation (poop is thicker than peanut butter)
  • diarrhea (watery, drippy poops)
  • blood in the stool or in vomit (which would cause a good parent to call the doctor)
  • hives or a rash (signs of an allergy)
  • other signs of illness (limpness, clammy skin, etc.)

Any of these signs are indicators that you need to try a different brand, or switch to a different Formula Family, like goat’s milk.

Force the Mob to Get Along

Switching baby formula is really a lot easier than you may think.  Just keep these things in mind:

  • If you’re going to switch to a formula that is from a different “Formula Family” listed above, introduce the new one a little a time.
  • Watch your baby closely during the transition to make sure no allergies are popping up.
  • Talk to your doctor if you think a specialty formula (low-iron, hypoallergenic, lactose-free, etc.) may be required.

If your baby seems really fussy on his current formula, by all means try switching baby formula.

Give that a week or two to see how it’s affecting him, and then, if you need to, switch again.  I mean it!  Don’t switch to more than one formula in a single week!  His little body needs at LEAST a full week to try out the formula before you can know for certain.  Switching too many times, too fast can really mess a baby up.

Be. Patient. 

And then keep trying (in weekly increments!) until you find the formula that is the best baby formula for your baby.

The more you try, the more you’ll know don’t work, and the closer you’ll be to the one formula that fits your baby.?

  1. Hello, I’m in need of some help. My baby is 7 months old now and is currently on enfamil soy. Since she was born we started regular enfamil formula… Then when she was 6wks the Dr said to switch to gentlease cuz she was gasy. So we did. Then she started spitting up a lot so the Dr said to switch her to soy… At like 4months old. She been on soy ever since and she still spits up. Not as much but still does it. A couples weeks ago he wanted us to try the nutramigen…. I didn’t. I really don’t think she has a milk allergy. My husband and I been thinking about trying the enfamil AR. How would I go about switching her? This is my second baby, my first never had any trouble eating. It’s like I’m a new mom all over again. Lol. Please any help would be greatly appreciated.

    1. Hello Elizabeth!

      First of all, you are doing a great job mothering this wonderful little baby. She obviously does have some gastrointestinal issues, and following your doctors’ advice is always a good idea. We are NOT doctors here at Incredible Infant, so whatever we suggest, we advise you to run by your doctor as well. If you’re wondering if your child does need a hypoallergenic formula, this article may help: . Another possibility is adding probiotics to your little girl’s diet. They have done wonders to many a baby’s tummy. 🙂

      Have a wonderful week with your little one!

  2. My baby is 2 weeks old. She was drinking similac advance in the hospital once she came home she was fussy and having major poops like 10 times a day so we switched her to Similac sensitivie , she did well but started acting colicky… Her grandma (who knows everything about children) went and bought enfamil nutrimigen because that’s what all her boys had to have. Well she’s been doing okay on it 2/3 poops a day and not very fussy, but she spits up and throws up after every feeding….

    I am so stressed over this and don’t know what else to do. I’m thinking the nutrimigen is to thin for her cause she never spit up on either of the other two formulas

    1. Hi Shelbie!

      I know that being a mom can be stressful. 🙂 Take a few deep breaths and know that you are the best mom for this little baby and the fact that you are asking these questions, prove that you love and care about her. Lots of people have lots of thoughts on Nutrimigen. I would first take her to the doctor and see what he/she recommends. Nutrimigen is often prescribed by doctors, but for allergies, etc .. It is often more expensive, and Similac Spit up might be a cheaper alternative. Also, talk to your doctor about possibly using probiotic drops which might help her with her tummy. Best of luck and give that cute baby a squeeze from everyone here at Incredible Infant.

  3. My 3 1/2 month old has been on Gentlease since 3 weeks old because he was very gassy. It helped but he still had pretty bad gas. However, since abut 3 months of age he has not had any problems with gas. He has always had trouble with constipation. At the moment we are in Bermuda and have only one tin remaining. We will need at least two more before we return home but we have pretty limited options as far as the availability of brands/types of formula. I cannot find gentlease but I was able to find the regular infant formula. Would transitioning him to the regular formula make his constipation worse or make his gas return?

    1. It’s hard to predict how a baby will respond to a particular formula, you just don’t know until you try. That said, you could try a few things to minimize his constipation and help prevent gas – regardless of what formula you end up with. This article will give you pointers on overcoming constipation.

      In regards to the gas, ask yourself where the gas seems to be located. Is he burping a lot? Try gripe water. Is it toots? Try probiotics. Hopefully this can help, Shannon!

  4. Hi there! We started our baby on Enfamil Gentlease when he was 2 weeks old because I was not producing enough milk and we had to supplement. He was fine for three days and then became constipated and fussy. We switched to Smilac Sensitive the following week and it was worse constipation. Finally the 4th week we switched to Gerber Good Start a Gentle and he started to have regular bowel movements, but they were forest green and smelled horrible. He also started to have more gas around this week and would constantly strain and push about 45 mins after each feeding. He would wake up crying eventually from the pain of trying to push gas or have a bowel movement. We had him tested and he is not lactose intolerant. We used the good start for 3 weeks and the gas issue continues to get worse. Baby was only sleeping 10 hours a day and woke up every hour crying and constant pushing/straining. Finally we decided to move to a hypoallergenic formula and started Nutramigen. Still no improvement and we also stopped breast milk for 4 days while I pumped and stored to see if that was the problem. No improvement either way. Any idea why this happening? We are thinking about giving alimentem a try to see if that helps the baby. Baby does have reflux and is taking meds with thickened formula using rice cereal. We have tried gas drops before each feeding and gripe water which did not help us either. Any help would be great. Our prediatrician is pro breast feeding and does not provide much input on formula. Baby has been gaining great weight so that has not been an issue.

    1. Niralee, I would recommend you get a second opinion if your current pediatrician isn’t giving you the information you’re looking for. Usually you have to remove foods for longer than 4 days in your diet to get a good feel for what’s affecting the gas. Have you considered probiotics? Christi wrote a great post about how that can really help fussy babies (and science shows they can really help reflux babies). Click here to read her article. Also, keep in mind that you may have to stick with a formula for several weeks before you can really tell how it’s affecting his tummy. Consider the probiotics, and seek a second opinion about the formula – just to cover all your bases. Then I’d stick with Nutramigen (or Alimentum) for at least two weeks before switching again – with your doctors approval, of course! Hang in there, friend. These days are SO HARD, but they do pass eventually. Every day passed is one day closer to getting beyond it!

  5. Hello. My baby has been on Similac Sensitve for the last month. She is currently 2 months old. The only issue has been what appears to be painful gas. We use gripe water but it doesn’t really work and she hates it. I switched to Enfamil gentelease yesterday, mixing the two. All of a sudden she is vomiting or forcefully spitting up (can’t tell). It is fairly large quantity and after each meal. She did not do this before. Should I continue with the transition or stop? I’m assuming it’s not an allergy as the ingredients of the two are very similar. Thanks for your help

    1. Hi Jamie,

      First of all, you will want to visit the doctor if she is still vomiting to make sure that it is NOT a medical problem.
      Second, I think that if she was happy with Similac Sensitive for so long, then you should stick with the formula she was used to. There are other ways to deal with gas. Adding probiotics to her diet might prove to be the answer. Click here for the article and hopefully that will help. Thank you!

  6. Hello
    Imy having some trouble with my son’s formula and hope you can help me. My son is a week old and I started him on low iron concentrated formula. We switched to powder yesterday of the exact same formula and he would not drink it. He was up for 4 hours in the middle of the night and nothing would settle him. I gave in and gave him the concentrated he drank most of it then went to sleep for 4 hours. Is there a way to transition him from concentrated to powderor am I stuck giving him the concentrated now? I wasn’t expecting an issue since it was the same formula.
    Thank you

    1. I would follow the schedule above, substituting water and powdered a little bit at a time to help him get used to the slightly different taste. Try that, friend, and let me know how it goes!

  7. Hello, my son is 8 months old now and on puramino milk for his acid reflux, and I was wondering could I try to give him regular unfamiliar now? When he was born they had him on newborn enfamil and I also breastfed him. My breast were sore so I couldn’t do it as much. When he was 2 weeks they gave me regular enfamil through WIC. Shortly after I found out he had acid reflux and they put him on neutramagin (sorry spelling)and zantac. That didn’t really help him but I keep him on it cause the Dr’s told me to give it a chance. They gave me samples of the puramino one day and it worked like a charm so I took him off the zantac because he didn’t need it but WIC wouldn’ give it to me because they said his diagnosis wasn’t bad enough for that milk. So I started purchasing it myself. The drawback was constipation. So they put him on generlac. Now that he’s 8 months old I was wondering should I try regular enfamil again??

    1. Honestly, this is a question that needs a doctor to answer. 🙁 Your baby should have a physical exam to see if the reflux is getting any better, and then your doctor will be able to advise you best on which formula you should continue to use. Sorry I can’t be more helpful! I just know my limits, and medical advice is one of them. 🙁

  8. Hello:) I’m a first time mommy & I have been having some issue’s on trying to find the right formula to give my 6week little boy. I’ve already have tried a few different formulas when I’ve made the switch I have always consulted with his pediatrician. The first brand I gave him was they mail in samples of enfamil then similac the first one I bought and gave him was the gentlease which caused him gassiness we switched to newborn which caused his constipation and very fussy then tried him on sensitive similac he still remained constipated so I was told to add a little bit of prune juice with his formula which helped a bit but still caused his constipation. We ended up having to switch back to enfamil since WIC only provides enfamil I have put him on enfamil reguline which has worked well with his stools but I think he maybe pooping a little to much. His stools are grayish green runny and little watery. Sometimes there is a little yellow in there. Will this clear up? Will they stay runny? He seems to not like the taste of the formula but manages to eat it since I have no other formula to give him. I have read about mixing gen with reg 50/50 but I am not a formula expert. I just want my little one poops to be normal and him to like the taste of the formula. Also he still cries to get his poop out even though it’s runny. What should I do:(

    1. Ashoolah,

      This is absolutely the kind of question you want to take to your pediatrician. Since your little guy is still so young it is important to talk this through with your doctor. You could start by calling your pediatrician’s office and talking to the nurse. Hope this helps! Also, here’s an article about constipation for your information.

  9. We are on the 4tg formula. My baby was gentlease but was hungry every 2 hours and had tons of liquid poops (up to 9 times a day) and spitting up out her nose as well as baby acne. Dr had us switch cold turkey to enfamil prosobee. Its now been 24 hours and no spit up, she goes 3 to 4 hrs between bottles and acne cleared up. BUT she’s constipated! She has had 3 diapers with small play dough like balls of poop. I’m nervous switching cold turkey caused that. She’s uncomfortable when she goes but had lots of issues with milk formula. Should I wait? Should I go back and mix gentlease with prosobee? Dr wanted child turkey because she obviously has a milk allergy. I’m just not sure what to do. All her symptoms went away with the switch except now she’s stopped up.

    1. Oh, not fun! I know.

      Take a look at our article on constipation. It will give you some good ideas of how to deal with this issue. If you can wait it out a full week before you decide about the formula that would be best. Hope this helps!

  10. My lo has been supplemented with soy formula one bottle a day and she is 8 months old we are now thinking she is out of her lactose intolerant allergy since she is past the 6-month mark wanting to transition her to Similac Sensitive should I do your ratio of 3 to 1 for a week we have recently just done a 50/50 split and it seems she has a good consistency but a yellow poop which is totally different than the poops she had been having which were hard and brown

    1. Whitney,

      Yes, do start with the 3-1 (maybe you are doing this already). That should help her little body adjust!

  11. Hi i’m a first time mom. I didn’t know that I had to ween.between formulas. I was given at the hospital the similac supplement then on the 4th day at the hospital was given similac advance. So we continued him on that but noticed after a couple days he was having trouble pooping. So we started giving him the supplement again since he was fine with that. But he still was having trouble going. So yesterday we tried the powder formula of similac advance. Did we have to transition him slowly or is it ok that I switch completely since it’s the same family? I’m really worried because it seems that it’s not helping. I’m afraid to switch him again because he is only 13 days old. Any suggestions on what I can do? My LO is still having trouble going. Also since I switched to powder he spits it out after a half hour of each feeding could this be that it is not sitting well with him?

    1. Bsorto,

      Since your little one is so new I would take all of these feeding questions first to your doctor. If you are staying with a milk based formula then you shouldn’t have to transition slowly. However, some babies don’t do as well with the powder, they prefer the pre-mixed. You might want to go back to that for a couple of months and then try the powder when your baby is a bit bigger. Also, take a look at our article about constipation. Hope it helps!

      Congratulations on your new little one!

  12. My daughter is 2 weeks old and has been fed a combination of breastmilk with ready to feed Enfamil (50/50). I will need to switch her completely to Enfamil as my milk is almost gone, but I also want to start using powdered formula. Do I need to do a slow transition from ready to feed to powdered? Or can it be a immediate switch? Any pros or cons for using one type of formula (ready to feed vs powdered) over the other?

    1. Lena,

      We find that most people feel like the ready to feed is a little easier on babies’ tummies. That being said, I think doing the switch gradually is a good idea. Hope it goes well!
      Also, are you familiar with the organic brand, Holle (you can only buy it on line)? It’s quite new on the market so we are trying to make sure that everyone knows it exists.

  13. Hi. My son is 3 months old. He used similac advance while he was in the hospital and one day at home, so about 4 days. I switched to Gerber soy and I honestly don’t remember why. So he’s been on soy since then. He has a really hard time passing stools. This started about a month ago . I gave him prune/apple juice diluted of course. And that helped at first. He has a real hard lil ball every now and then but for the most part his poo is very pasty/clay like. He was such a good baby never cried unless he was hungry. Now he has ‘fits’ throughout the day. I now know the fits are him straining to have a bowel movement. He turns so red and he is in so much pain it hurts me to watch him. I’ve tried everything, from the juice to pedialyte, to leg exercises… And nothing helps. I took him to his dr he said it was normal and as long as he is gaining weight he was fine. And I asked about switching formulas, he said I could if I wanted to that it was up to me. So my question is, if I wanted to test out another formula that could maybe help with his bowel movements, which one would be the best? Or should I just stay on soy, and eventually things will get better?

    1. Sina,

      The first thing you need is this article about constipation!

      Regarding switching formula, if you don’t have a compelling reason to be using soy I don’t recommend it. Of course it’s up to you, though if you want to do the switch. If you do, take a look at this article about how to do it gently. It might be a good idea for you to start with something like Similac Sensitive or Gerber Good Start Gentle. Hope this helps your little guy!

  14. Is there any formula for gas, constipation and reflux?

    My twins (5 mo) seem to always have at least two of these symptoms depending on the formula I try.
    Neosure (bc they were preemie): reflux and constipation
    Gerber Gentle: horrible reflux and gas
    Similac for spit-up: milder reflux, constipation
    Enfamil for spit-up: milder reflux, bad gas, mild constipation

    What am I doing wrong!? My dr says I have to choose which is worse and deal with the rest. Really!?
    They are on Zantac but it doesn’t help much. 🙁

    Thanks for any help. I am at a loss!

    1. Wendy,

      I would recommend that you start them on probiotics (if you haven’t already). This can help with both the reflux and the constipation…and the gas too, for that matter.

      When they are 6 months old you can try this brand instead. It’s only recommended for 6 months and up, however.

  15. Hello,

    I was hoping for a little guidance. My 5 month old son has been on Gerber Good Start Gentle since about 6 weeks old and I’ve noticed his eczema getting a lot worse. It’s all around his face and chest now. He has not had any tummy troubles just skin issues. His older brother has cow milk allergy and soy allergy as well as eczema but eczema has improved significantly with removing those from his diet. Should I switch my 5 month old to something else? Should I assume he probably also has the allergy my older one does? I am thinking of trying hypoallergenic formula, do you think that will help his eczema?

    Thank you for your time.

    1. Joanna,

      First, I recommend you run all this past your pediatrician but, yes, I think you’re on the right track. With your family history and the symptoms you are describing it seems like a good idea to do the switch. You could start with whatever hypoallergenic formula worked for your older son and do the switch gently as recommended in this article. You might also want to add probiotics to his routine. These can help his more sensitive digestive system work more efficiently. I hope this does the trick for your little guy! Also, I recommend you go ahead and get him tested for food allergies at the age recommended by your pediatrician (ours recommended 12 mo.).

    2. Thank you! We have made the switch to Nutramigen and his skin is 100 percent better already. Will definitely look into the probiotics and allergy testing around a year. Thanks again for your time.

  16. My daughter is currently almost 10 months old. I switched her to Good Start soothe at 2 months due to her reflux and it was amazing! She is no longer on reflux medication, she’s eating solids and I’m hoping to transition off formula at a year. However it’s becoming harder to find it in stock at my local store. I’ve been toying with the idea of switching her to Good Start gentle because is always in stock. I looked at the ingredients they are the same (except the probiotic) just in a different order. Would it be crazy to switch her at this point? Is there that much of a difference between the two?

    1. Melissa,

      I would really trust your mama instinct on this one. It’s hard to say how she will take the switch. She might be ready for it now that she is 10 months old. Her digestive system has developed a lot since 2 months. Soothe is more mild because it is just whey which is easier to digest. If you decide that you want to stay with the Soothe then I would check out Amazon’s Subscribe and Save.

      So, your decision. I’m sure you will figure it out, mama. Seems like you did a great job at 2 months!

  17. Im trying to switch my baby from ready to feed good start to powdered good start but he refuses to drink… i tried making a slow transition 3:1, he still wont take it… then i gave him 5:1 he still refuses.. im so stressed!! Hes almost 7 months and still on stage 1 cus ready to feed doesnt come in stage 2. I even tried giving him simiac since it tastes better but nope! Im travelling end of this month and the country im ravelling to doesnt carry ready to feed formulas so i HAVE to make a transition and QUICK!! PLEASE HELP MEEEE

    1. Since this is a feeding issue, Faryal, I’m going to have to refer you back to your doctor. I’m sure they’ve seen this more than I have. I like the 5:1 idea, perhaps try that for a few more days…then 4:1 etc. But definitely check in with your doctor. He/she may have some secrets here that I’m not aware of!

  18. My 5 weeks old has been ebf but I want to make the switch to formula. She spits up so much curdled breastmilk after every feeding. I know I could try harder to change my diet but I’m just losing my mind with no sleep from being tied down all the time! So her pediatrician gave me a can of Gerber soothe we tried it for two days and she had foul gas and explosive out of the diaper diarrhea. So went back to nursing. Then I read about similac sensitive so I gave it a try. Gave her I would say 3 bottles of it. She had the same diarrhea. So back to nursing again. Should I stop at the first sign of diahrrea or give her more time to adjust. Any ideas on a formula that could work? thank you!

    1. Naomi,

      It’s really up to you, but is there a chance you could give her a little more time with just the breast milk before making the switch? Is the doctor worried about weight gain or is it just the high amount of spit up that has you concerned? I completely understand the “desperate for sleep” feeling!
      I recommend, either way, you get her on some probiotics. That will really help her intestines.
      If you want to try the breastfeeding again we have a brand new article about diet (just in time!) you can take a look at.
      If you want to do some more research into formula this article will be helpful. Since she reacted the way she did to Gerber Soothe and Similac Sensitive you might want to look at this article as well.
      And to answer your last question: I would be concerned about the diarrhea. I think you made the right choice to switch her back right away. Since she is still so little dehydration is not something you can risk.

      I hope this helps and you both get better sleep soon!

  19. Hello,

    I have a 2 month old baby girl I am giving her good start for newborn formula.  I have a question she doesn’t like to drink it initially she was ok with it but gradually I think she doesn’t like the taste of it can you guide me what I can do any advice would be appreciated.


    1. That happens sometimes! A baby just doesn’t like the taste of the formula. Choose a different brand (like Similac or Enfamil) and use their standard formula for a few days. If you’re worried about gas as you’re switching, take a day to slowly switch over (1 part new, 3 parts old, then 2 parts new, 2 parts old; then 3 parts new, 1 part old, etc. This way she the shift is easier for her to get used to.

  20. My baby boy was started in Gerber Good Start Soothe while spending his first week in the NICU. Unfortunately breastfeeding was a flop for me so we are on formula only. He is now 5 weeks old and has all of a sudden (for the last 3 nights) gotten EXTREMELY gassy. All night long he makes straining noises to poop and even cried out in pain sometimes. His stool is not overly hard or too sticky when he does pass it. I’ve read multiple posts of yours and I’m so torn between if this is a newfound reaction to the formula he has been doing great on up to now (very little spit up or gas until now) or is it maybe dyschezia? He strains and whimpers literally all night long. During the day he does it some but not as much. He has also become extremely gassy the last few days, farting almost constantly. I also have noticed the red ring that you discussed in your other posting. Any advice would be greatly appreciated!!

    1. Kayla,

      Poor little guy! It does sounds like his formula is not a good fit. Have you taken him in to see your pediatrician? I would start there.

      Since you are seeing some signs that this may be related to either a sensitivity or an allergy I would take a look at this article on hypoallergenics. He might need to switch to one of these for a while until his digestive system matures a bit more. I would definitely run all this by your pediatrician though.

      If you do decide to switch your little guy to a hypoallergenic formula remember to do it gradually; start with 25% of the new and 75% of the old formula. Try that for a day and if it goes well move to 50%/50% and from there to 75%/25%. If all goes smoothly you should be at 100% of the new formula in a couple of days. The extra time should help his intestines stay calmer as you make the switch.

      I also recommend that you consider starting him on probiotics. I hope this makes the difference!

  21. Question: if a baby at first shows signs of a problem (excessive gas and lots of crying in our case), is that enough to say the formula itself will not work?  Or is it a matter of letting the system adjust to it and all may be well in time?  Want to reduce any unnecessary headache.

    Background: our baby got on Similac Advance soon after the hospital to supplement breastfeeding.  We tried switching later to an organic one (still milk-based), but got a ton of gas and crying.  We tried another brand, and the same.

    1. Doug,

      Good question! We usually recommend a week with the new formula before you decide if it’s a good fit. It does that a couple of days for the baby’s digestive system to adjust (and it’s great if you can help by doing the switch slowly, 25% of the new formula with 75% of the old, 50%/50% and then 75%/25%) That being said, I think you also have to decide in the moment, if your little one is in a lot of discomfort/pain then you need to make that call. It’s ok if you decide that it’s not worth pressing through for an entire week.
      I recommend you try probiotics for your little one. This could help settle the digestive system.

  22. Hi!
    My 3 month old son began vomiting about a week ago. No fever. Just vomiting and diarrhea and a rash. I suspected a milk allergy and took him to the doctor again. They had initially said it was a stomach bug. However, this time the doctor gave me a hypoallergenic formula to use. We had been using Similac Advance before. I didn’t transition him slowly. I think he is doing better, but he has thrown up again. I’m worried that the quick switch will make it hard for me to know if the formula is helping or not. What are your thoughts?

    1. Victoria,

      I hope your little guy is doing better. I’m sure your doctor talked to you about dehydration, how dangerous it is, etc… Anyway, If he is staying hydrated we recommend a week with the new formula before you decide if it’s a fit. Also, take a look at this article about hypoallergenics. It should help you as you decide.

  23. Hello!
    I have a 3 month old baby boy whom just started to take “Nestle Good Start Easy Digestion” but I wanna use the same formula but the one with omega 3 in it. My question is: do i have to do a slow transition again with this one? Or it doesn’t matter since it’s the same one but with an extra “ingredient”?… Thank you!

    1. Eva,

      It probably is fine to go without the slow transition since they are both “dairy based” formulas.

  24. I had my baby on regular newborn enfimal and she wasn’t pooping then I switched to gentle ease and it worked great but I switched back to regular formula and now she is having hard time pooping again.

  25. My 2 month old have been whining and crying since 2 weeks. The episodes start at night around 9:30; it used to be around 11:30. It lasts for 3 hours or more now. Some nights it used to be for an hour and half but it seem to have gotten worst. The Pediatrician think it’s silent reflux because he don’t spit u. He has been on Zantac for a month and it’s not better. He sleeps elevated and after a feeding, I hold him for about 20 minutes before I lay him down. He even had Prilosec but it made him scream more than what he was doing so we went back to Zantac. He had dry flaky skin since about 1 month and then it went on to red little rash bumps on his neck and shoulders, and his skin was light and dark in some spots. The Pediatrician prescribed a cream last week and the skin is getting better. He is always sound like he has a cold and wheezing; especially after he feeds. He cry through 80% of his feedings. He cry when he poops 85% of the time. The crying episodes used to be a few nights out of the week but the last two weeks, it has been every night and it starts at around 9:30 and lasts for about 3-4 hours. It starts with him licking his lips, clinching his fist, and arching his back. We console him and he will stop for about 15 minutes on and off but then he start back crying after that. They said it may be colic but it’s not a constant cry. We tried 3-4 different gripe waters, gas drops, and Gerber probiotic drops and nothing really works. We have been on several different formulas. (Gerber Gentle at birth and then Neosure before we left the hospital because he was a preemie, Similac Sensitive because he started having these issues, then Gerber Soothe, Soy, Alimentum and now back to Soothe.) Alimentum gave him bad diarrhea so I took him off and it didn’t seem to have been working after  weeks on it. He sleeps like 1-2 hours and he cries and whines in his sleep 85% of the time. How do I know if he needs hypoallergenic formula? He has no blood in his stool and it doesn’t look like mucus. (The doctor checked that at the ER.) His poop is pasty  sometimes, but regular looking with a seed look most of the time. He is never constipated. I just need some relief because  my sanity is at stake here. My husband had to take a leave of absence from work because I was running on 2-3 hours of sleep, but he goes back next week, so I need any suggestions. I would definitely appreciate it.

    1. Shannon, I would absolutely request a referral to see a pediatric gastroenterologist. He is a specialist in digestive issues like this. That’s the first call I would make today to your doctor, seeking that referral and setting up an appointment. Secondly, I would talk to your doctor (or the specialist) about whether it would be better for you to use an amino-acid formula like PureAmino or Elecare. Thirdly, I would give you a hug. 🙂 Because you are definitely earning your “Parent Longsuffering” Badge. Know that as bad as this is, you are doing the right things to resolve it – asking a LOT of questions, trying and testing, trying and testing, to move closer to a solution. That is good parenting. Get yourself some earplugs, switch off and on with your husband, and do NOTHING but the bare essentials as you work through this. It is difficult, absolutely, but it is a season. This isn’t going to be your life forever, and the good news is you’re probably closer to the end than you are to the beginning. Perhaps this won’t encourage you, but I did stop typing and pray for you. Continue to keep your eyes on the horizon and try to keep them OFF the immediate discouragements of the present. xoxox

  26. Hi there!
    Ok so when I started my little man (3 weeks old) on formula I started him on the Similac sensitive (I didn’t realize how different all these formulas are!) And I then tried some regular similac for a couple days but he had diarrhea so I stopped it and went back to the sensitive. I realize now he may have just needed more time but I thought he had an intolerance. Well I am now on wic and they won’t approve the Similac sensitive so asked if I wanted the regular similac or soy. I went ahead and chose soy. Well the first day we mixed it together to slow transition him. He had some constipation but it got worked out. Well day 2 we went out of town and accidently only brought the soy so I had no choice but to give him the soy. Now he is so fussy and is having diarrhea again. Should I start mixing it again with the sensitive or now that he has had a day and a half of just soy just stick it out for the week to see if he starts to tolerate it? I feel so bad. Anything I can do right now to help his tummy?

    1. Jessica,

      Have you talked to your doctor? Since your little guy is still so young the diarrhea makes me nervous (because of the risk of dehydration). Contact your doctor and see what he says.

  27. I have a 3 months old with flaky dry skin on the face and around the head and has hives on the body. They said its milk allergy. I have been taking him to the dr. For a month now…. I used milk formula n recently changed to soy base milk. It’s been over 4 hours since I changed it. How long does it take for it to work?

    1. Jess,

      I hope this is a good change for your little one. We recommend a week on the new formula before you decide if it’s a good fit. It usually takes about that long for your baby’s body to settle in to the new formula. If soy doesn’t work out (sometimes babies with milk protein sensitivities also have a sensitivity to soy) then you might want to take a look at this article about hypoallergenic formulas. Also, this article with one mama’s story about dealing with a milk allergy might be an encouragement to you!

  28. I had my baby on enfamil reguline. She did great on it. We just could afford to keep buying it and WIC won’t help. So theu recommended trying her on enfamil nutramigem. Shes been on it a full day. Her eating has decreased dramtically & she hasn’t had a bowel movement since she started the new formula. When she was on the reguline, she has a bowel movement everyday. Shes extra cranky & seems like she can’t poop. What should I do? Keep trying the new or put her back on the reguline that worked?

    1. Maggie,

      Did you try the gradual switch (starting with 25% of the new formula and 75% of the old, go to 50/50 and then 75/25 ending with 100% of the new)? If not, you might want to back up and try that. Also, we recommend a full week before you know if the formula is a good fit. It might take a good 5-7 days for her digestive system to regulate back to normal. However, if she continues to be backed up take a look at this article for lots of good suggestions! Also, keep your doctor posted on her progress.

  29. Hi,

    My baby is 2 months old. He was originally on enfamil newborn but he was very fussy and I decided to try Enfamil Gentlease which was working just fine with him. I took him to the doctor and told him he had been very fussy, gassy and spitting up milk and he decided to switch him to Enfamil AR because he thought it was acid reflux. Its been 4 days and my baby won’t stop crying, he is constipated and super gassy. I have tried gripe water and mylicon and nothing works. What should I do??

    1. Yolanda,

      Switching formula can be a bit rough sometime, yes?! Sorry your little guy is so uncomfortable. I have a couple of things to suggest. For the constipation talk to your doctor about adding prune juice to your baby’s bottle twice a day (For babies younger than 4 months, mix in a tablespoon of prune juice in 4 oz of formula or breast milk). Also, take a look at this article about constipation.
      The other thing I recommend is probiotic drops. These help with gas in the intestines (the gas drops only help with gas in the tummy). Try to get through the full week with the new formula before you decide if it will work. After one week if things are not looking up then it’s time to try again. Make sure to do it gently (25% of the new kind of formula mixed with 75% of the old, going from that to 50/50 and then 75/25 if things are still looking good).

  30. Hello there!

    My daughter is three months and is extremely fussy. She has been prescribed zantac, but it does not seem to be helping. She is currently on Gentlease by Enfamil. We tried Nutrimagen by Enfamil for a week with no success when she was four weeks. I tried re-introducing it, following the 1-3 ratio; she was fussy throughout her feeding and vomited afterward. I just do not know where to go from here.

    1. Ivette, I would touch base with your doctor so he’s aware of the formula change and what happened. I would ask him about adding baby probiotics, which have recently been shown to be helpful for reflux babies. I would also ask him about the potential of giving another reflux-medication a try – like Prevacid. Prevacid can only be prescribed for a short period of time, but considering her age, it might be the time. (Reflux usually peaks between 3-4 months.) Zantac doesn’t reduce the reflux, it just makes it less acidy. Prevacid actually reduces the acid altogether -which is why it can only be used for a short time. That said, the timing may be right to use that Trump Card now, when you might be close to the end of all this. Lastly, perhaps try a different hypoallergenic brand – like Alimentum. Some babies just do better on different brands. I hope this can help, friend! xo

  31. My son was EBF for 7 weeks and did not do well: distended stomach, extremely colic, mucus poo, vomiting. I finally took him to the pediatrician after i put it all together. We went straight to Alimentum powder and he was like a new baby. So, then after a few days he was extremely gassy so I thought let’s try the RTF. He was still gassy for a bit but seemed to do great on it. I have taken him to an allergist and a GI specialist and was basically told “breastfeeding was working! he was gaining weight, i don’t know why you quit” well my baby was miserable and now i feel stupid. did I overreact? was i not equipped to deal with a screaming baby and should’ve pushed through? My baby was flailing for 4-6 hours a night, during the day, screaming, crying, never had that yellow-seedy poo he was supposed to. Anyways. We have had a few vomit episodes. The past few days (it’s now been 2.5 almost 3 weeks on RTF alimentum) he has been very gassy again, arching his back, just PB-like poo with no substance/chunks like i see in normal formula poo pics, and he is spitting up EVERY feeding. We have a bunch of neocate, but when i tried that (after he had a severe vomit episode after a “negative” iGe test i believe he reacted Gastro to the proteins absorbed through the skin) he got hoarse and had bad reflux again. He is also on reflux meds twice daily, famotidine. Does this mean the alimentum isn’t working again? I’ve heard of this happening but I don’t want to jump to assumptions. Should we try a milk based or soy based formula while I’m still staying home and see how he does for a week? He is 12 weeks old. Any opinions welcome!

    1. Amy, first my apologies in not responding sooner. Totally my bad! Secondly, don’t feel stupid. Woulda coulda shouldas are the killer of lots of good parents. 🙂 You made a decision based on the information that you had, and so don’t use up any emotions looking backwards. It will only cause ulcers. 🙂

      Seems like you have two options to discuss with your GI doctor. 1) Switch to a different hypoallergenic formula like Nutramigen. 2) Go up the ladder to the hyper-hypoallergenic formulas (PureAmino or Neocate). Click here for more on those.

      I would also check over the reflux meds again and ask your doctor about introducing probiotics as well. New studies have shown they can help reflux babies. I’m so sorry to hear you’ve had a rough 12 weeks, Amy! Let me reassure you – you are doing a GREAT job advocating for your little man. Keep asking questions and seeking answers. You may find Chelsea’s story encouraging. She walked a similar path, and she can encourage you that it does end! xoxo

  32. My 7 week old has been on Similac Advance (blue can) since birth (he had an undiagnosed lip tie and tongue tie untik 2 weeks ago and I’m in the process of building my milk supply. He started getting more gassy tham usual so we switched him to Similac Partially broken down 6 days ago. We didn’t introduce it slowly because we didn’t know to 🙁 he got gassier and more fussy on this formula (I’m realizing it was likely due to the sudden switch). His stools became dark green and pastey. We went to the clinic and the doctor suggested similac sensitive. Of course again not knowing to switch slowly we switched yesterday. His gas pains are hugely worse I feel like a terrible mom switching him too fast. Now I don’t know what to do. Do I keep him on the similac sensitive even though his gas pains got worse?

    1. Katrina,

      Yes, do keep him on the Sensitive and let his little digestive system have about a week to settle. You work with the truth you have, mama; don’t feel guilty about not knowing!
      I also recommend starting him on probiotics. This will also help his digestive system.

      Hope he’s doing better soon! Good job being determined and continuing with the nursing even with all the challenges. I am impressed by you!

  33. Our baby girl was on Similac Advance since birth. At about four weeks she was starting to get fussy after feeding and screaming in pain when we would rub/touch her tummy. We switched over to Sililac Sensitive and she did a complete 180, she was more alert, more awake after feeding, didn’t cry in pain. After about four days she got the runny poops, she seen her doctor and he said it was normal while she adjusted to the formula. Well it has been five days after seeing the doc and she still has the poops and her bottom is so red. I’m not sure that formula to try next. Similac Soy or Similac Total comfort?

    1. Kelsey,

      It sounds like it might be time to try a different brand. You could try Gerber Good Start Soothe or Gentle…
      You could also start her on probiotic drops. They will help her little digestive system.

  34. Hi!, my son is about to be 2 months, I’ve had him on enfamil newborn formula but its too expensive so I got on wic and we put him on similac sensitve is this bad? With the enfamil his stomach acted up and couldn’t poop at times.

    1. Mia,

      It sounds like this could actually be a good change for him! How long has he been on the Similac? We recommend trying a new formula for a week before you decide if it’s a good fit for your little one (it can take about that long for their digestive systems to settle with something new). Also, if your son continues to have problems with constipation you should take a look at this article.
      Hope this all will mean a happier baby!

  35. So our LOL has been on everything… breastfeeding went terrible and she was miserable. We’ve tried similac advance, enfamil gentleease, and finally ended up on Soy. We’ve since been able to switch her to Parent’s Choice sensitive (more financially feasible) with no issues, but I’m not completely impressed with corn syrup being the main ingredient. Am I a terrible parent for wanting to try to get her onto the Parent’s Choice advantage formula and do you think that’s a wise move??

    1. Lindsey,

      We are really big around here on encouraging mamas to trust that mama instinct! If you aren’t comfortable with the main ingredient being corn syrup (I’m with you on that!) then try something different. I would recommend doing it gently as this article states. Begin with 25% of the new and 75% of the old formula in her bottles. After you try this for a day or so you can switch to 50/50 and then 75/25 and then 100%. This way you give her digestive system a chance to adjust with each change (and they are little changes). Also, you might want to get probiotic drops for your little girl. They can really help that little digestive system while it’s still so new and immature.

  36. I BF and supplemented basically from two wks on. we tried enfamil and he seemed to puke both kinds up. so I tried my sample of similac sensitive and it seemed to work great but once the BM got cut out completely he startes not pooping for days, I kno they say this is normal n such but he was extremely miserable and uncomfortable, so after weeks of this we decided to switch to similac “discomfort” bc it said partially broken down proteins. well this one he seems to poop a little better but I have to help stimulate him but he does go, but hes puking all the time with this one. so idk wat to do. but its been almost 2wks and ppl keep telling me to hang on and he meeds more time to adjust n stuff…..but I kinda feel like 2wks has brrn lonh enough and why would he stop puking all the sidden if I keep hi on it longer. tonight I stupidly tried to switch him to gerber goodstart soothe (wanted to try gentle but got sample of soothe) just gave him a bottle and he projectile vomited. it was bad. now im scared to try it. idk what to do, I feel horrible bc I cant get this figured out. hes so fussy 🙁 and I keep bringing him to the pediatrician and she seems to blow me off and as long as he’s gaining shes not concerned but she doesn’t live with him and see him upset all the time like I do! plz help! idk wat to do

    1. Teisha,

      Oh, I’m sorry this has been a challenging time for you and baby! When you tried the Gerber did you mix it with three parts of the Similac? Now that you’ve read the article you know that it’s better to switch gently from brand to brand (even if they are both milk based). If you want to go ahead with the Gerber Soothe try mixing it with the current formula this way: start with 3/4 of the old and 1/4 of the new. Try this for a day. If things are going well then try 50%-50%. If everything still is working out then you can try 3/4 of the new and 1/4 of the old and on to 100% of the new after a couple of bottles. This process should take a couple of days. Try the new formula for a week before deciding if it’s a go.
      I also recommend that you try probiotic drops with your little guy. These will help his little digestive system.
      If you don’t feel like your doctor is listening/helping I really recommend you consider getting a second opinion!

  37. My baby is 4.5 months and has been on similac sensitive for 2 months now and she has been doing good on it. For the past week, we switched her to similac sensitive non GMO since I have been reading on how horrible GMO are for babies. But since switching her poop has been a bit harder and painful when she is going. Should I go back to the regular similac with GMO or try earths best since it’s organic and also milk based? Now, I feel bad for switching but I don’t want the GMO to affect her mentally later in life

    1. Paulina,

      I hear you on this! You want to give them the best but it’s rough when your little one’s body doesn’t adjust. I recommend starting by talking to your doctor about adding a little prune juice to her bottles. This (just published!) article about constipation should help too.
      If none of those ideas help then it’s time to try another formula.

  38. I was EBF and supplementing with the Similac for Supplementation to get her used to the bottle before I went back to work. Long story short, I am back to work and due to a frustrated baby and a low supply we are weaning. I plan on using the rest of the stash of frozen breastmilk in my freezer and alternating between that and a formula bottle throughout the day. My question is…is it OK to transition her from the Similac for Supplementation to the Similac Sensitive, for example? Since she is eventually going to be on full formula I figured it was best to move away from the supplementing version, and the sensitive was great for my other daughter (who had a sensitive tummy, like this one.) How do you recommend transitioning? Make the bottles with half one kind and half another kind? For how long? Thanks so much for your help!

    1. Ashley,

      Going half and half with the formula and the breast milk should be fine (or if you want to be even more gentle you can try 3/4 breast milk to 1/4 formula to start and then go from there).

  39. I have had my 12-week old baby girl on Enfamil Infant, the ready-to-pour variety, since 3 weeks. She’s had no problems. However, it’s getting a little expensive and I’m thinking of switching to powder. I have the sample box from Enfamil with small cans of the Newborn and Gentlease varieties. Will it cause problems if I use those? Or should I just get powdered Infant?

    1. Jessica,

      I would recommend sticking with the Infant unless you are planning to completely make the switch to one of the other varieties. Different varieties do have a different mix of ingredients and switching around can be hard on your little one’s tummy. You can take a look at this article for an idea of how this works from brand to brand.

  40. Hi,

    My daughter is 7 months old and she has been on Similac sensitive for the first 7 months.  She is supplemented with breastmilk for bedtime…it is more of a comfort for her now then anything.  In any case, I had recently moved and Similac Sensitive is not readily available.  I wanted her to have an Organic Formula, so I found the best one on the market, Holle step 2.  I did not ease her into it fully, and it is more complex proteins, so my daughter has had diarrhea since I started the formula.  She has a bowl movement 5-7 times a day.  It has been over a week.  She is not fussy but I just think her stomach is having a really hard time digesting this formula.  She keeps getting a rash due to all these dirty diapers.  Anyhow, I am thinking about switching back to similac sensitive.  Should ease her back into the similac or just abruptly switch since she has not settled on Holle formula?  Also, should I try Goat milk by Holle brand?  Do you think that might work for my little one?  I am so desperate at this point.  I don’t know what to do, so anything will help here.


    1. The first thing I would do is to get her to the doctor’s office. We want to make sure she’s not getting dehydrated. They may also want to check her stool for rotavirus, so keep a sample of her latest diaper for the doctor. Goat’s milk is very high on protein, so it can be hard on baby’s kidneys. That said, some parents do use it – so make sure you’ve gotten a thumbs up from the doctor first. Goat’s milk may also be missing some of the other essential brain nutrients (DHA/ARA) so you may need to give her additional supplements. Check with your doctor, and let me know if I can do anything else. xo

  41. I have a silent reflux 3 month old baby on Zantac. We used Similac Advance since birth, but switched to Similac Sensitive due to lots of screaming (his sister was on a sensitive formula when she was an infant). Similac Sensitive was better, but after reading about Good Start Soothe here I wanted to switch to see if we could do better. I have been mixing 50/50 of the Similac Sensitive and the Soothe and the baby seems to be happier (actually smiling, cooing, sitting without fussing). Unfortunately he doesn’t seem to like the taste. He will eat a full 5oz bottle during the night just fine but during the day he seems to refuse the bottle after 2oz, unless really hungry. He takes in a “normal” amount of formula overall during the day. It has only been a couple of days at 50/50. Any recommendations? Keep on with the 50/50, scale back the Soothe to 25/75? I’d love to keep my (otherwise) happy little guy on the Soothe if I can.

    1. Amy,

      I think your idea is a good one, try the 25% Soothe, 75% Sensitive for a day and see if he likes the taste better. We do suggest you try each new formula for a week before deciding so why don’t you see how that goes for a day or so then try switching back to 50/50. If that is ok (perhaps he will become more accustomed to the taste as the week goes on) then you can do 75% Soothe and 25% Sensitive and then of course, 100% Soothe.

      If he never adjusts to the taste I recommend starting him on probiotic drops (you might want to do this regardless) as they have been proven to help babies with reflux. At 6 months you can switch to a probiotic powder. These will help keep his little intestines balanced! Soothe has the probiotic L. Reuteri which may be one reason he’s doing better already.

      I hope you can find the right combo for your little guy!

  42. Thanks so much Danielle. I really really appreciate the honest, sound advice. You read my mind…next two bottles I made this afternoon were 2.5 scoops nutramigen and 0.5 scoop Similac.
    We’ll see what she thinks of that. She’ll be just 4 months on July 30th.
    All this mixed with a growth spurt has been awful. I’ve been awake 17.5 hours and counting.
    I also went to the pharmacy and got over the counter medicine for gas. I’ll do that to.
    I’m determined to beat this and help her feel better. Just can’t believe the doctors opinion today. He actually sat in the room and looked at google images for formula and started rhyming off names! Couldn’t believe my eyes. Not professional at all.
    Last time ever at that doctors office, I’ll be getting a new doctor next tues 🙂 thank goodness

    1. Good news, Suzanne! You are a strong mama, I can tell. So glad to hear of your determination to help your little one.

      May you both have more sleep soon!

  43. Hi,
    I just took her to the doctor today and he was so incompetent. I’m so angry with him I could just scream.
    He just started looking formulas up on the Internet and rhyming off names. He kept cutting me off and not listening. I told him her diapers are just awful, today’s diaper exploded up to her nipples!
    I said we’ve tried everything to help her and she’s still not doing better. I explained we’ve had to mix one scoop of Similac and two of Nutramigen because she’s completely refusing the nutramigen on its own. He said that’s a huge no no and to have her just on one formula and if she doesn’t like the new formula she’ll just have to accept it. So I’m suppose to let her starve? Definitely not.
    I asked if she should be tested for allergies and he said babies don’t get allergies. He said all medical staff are concerned with is if she is gaining weight and growing and she’s doing both so there isn’t an issue.
    But there is an issue because she’s not settling and full of gas and has explosive diapers.
    So now I have no idea what to do 🙁 do I keep mixing and hope she adjusts? or do I put her just on Nutramigen and let her refuse until she’s so hungry she eats? Or do I change formula again? We’re only on day four of mixing.
    Thanks for your help and advice!

    1. Oh Suzanne,

      Nothing worse than not being heard when you go to see your pediatrician! My advice, get a second opinion if possible. Your doctor is there to serve you, to listen and to help you make the best decisions for your little one.

      In the mean time, I would try to switch completely to the Nutramigen. Since you have been doing 1 scoop Similac and 2 scoops Nutramigen try switching to 1/2 a scoop of the Similac and the rest Nutramigen after a couple of bottles (if she’s still eating!) try all Nutramigen. If that’s a bust then you may want to try Gerber Good Start Soothe instead. It’s very gentle and sometimes switching brands (from Similac to Gerber) does the trick. Usually we recommend taking a week with each new formula but if she won’t eat…

      How old is your little one? Babies DO sometimes have allergies. I just talked to a mom this week who took her 4 month old in for a prick test because her baby had such bad eczema (and allergies run in their family). Take a look at this article for some information in that department.

      Hope you can get a second option and better help soon!

  44. My baby has been very fussy and gassy since she was born. She was on the regular Similac (blue) but that really didn’t agree with her and she was projectile vomiting everywhere. I switched her to Similac Partially Broken down Protein and it seemed to help for quite a while but she’s still fussy and gassy and she wakes crying and scrunching her legs up at night and is really squirming. Plus her poo is really runny and very dark green.
    So just two days ago I bought Nutrimigen but she refused the first bottle so I mixed one scoop similac and two scoops Nutrimigen. She’s so gassy and unsettled. And when she passes wind she does explosive poo 🙁
    She won’t take the Nutrimigen on its own and this is day three and she’s so unsettled. I don’t know what to do.
    She just won’t stop and it’s awful seeing and listening to her so unsettled. What should I do?

    1. Suzanne,

      You need to take this to your doctor. From your description I’m a little concerned about dehydration at this point! Take a look at this article before you talk to your doctor. It gives good information about hypoallergenic formulas and also Hyper-hypoallergenics.

      You are very right to be concerned and SO right to continue to look for answers. Check in with your doctor about the possibility of acid reflux while you are at it. In either case (with or without reflux) it sounds like she could use some probiotics. Here’s the link for drops (under 6 months) and the link for powder (over 6 months).

      I hope you can find some relief for her!

  45. My daughter is 4 1/2 months old. We have been doing half and half breast milk and Nutramigin hypoallergenic formula for 2 months (after some terrifying bloody diapers, it was decided she has a cows milk allergy). We are now transitioning to full formula. Since starting full formula (a week ago) she is eating less, spitting up and crying much more. At what point should J try changing formula? And what should I try! My doctor suggested going to “normal enfamil”, but I don’t want bloody diapers again :S … Thoughts?

    1. Katie,

      I do think it’s worth trying the other brand of hypoallergenic formula, Alimentum. However, you should probably also talk to your doctor about the possibility of switching to a hyper-hypoallergenic formula. Take a look at this article for information on both hypoallergenic formulas and hyper-hypoallergenic formulas.

      Some other thoughts (which I hope will give you hope!), your little one might only need this kind of special care for a little while longer. At 6 months your baby’s gut will be developmentally stronger. In addition, 80% of children eventually completely out-grow a milk protein allergy!

  46. Hi, hoping we can get some help. We have started giving our baby formula for day feedings and I still breast feed her during her night feedings and her first morning one. We’ve been using Gerber gentle. This is the start of the 3rd week of using it. She has been super gassy and colicky. Starting to think we should try a new formula. I was thinking about similar sensitive. Not sure if we should try changing it or maybe this is still her body adjusting. She will be a month on the 3rd. Tonight was one of the worst nights for us she was crying, turning red and just seemed in so much pain. It upsets me because she gulps up the formula and it all goes well until she’s done eating.
    Any thoughts?

    1. Katy,

      We recommend that you try a formula for one week (maybe a little longer if you are only using it during the day) before you decide if it’s working. Sounds like it’s time to try something different! I think Similac Sensitive is a good next choice. I would also recommend that you give baby probiotic drops a try. These help with gas in the intestines. Also, have you tried a Rock N Play? This only works for babies 4-5 months and under (not sure how old your little one is) but is great because it keeps your little one’s head elevated which can help with digestion as well.

  47. I am wondering if I can switch directly from similac alimentum to Gerber good start soothe? My 1 month old is struggling with colic and a lot of gas. We were on similac advanced then moved to the sensitive and then under the dr to the alimentum. The dr started her on meds for acid reflux but they aren’t helping with the fussiness and gas. So we are thinking of changing to a formula that has some probiotics in them.

    1. Melissa,

      Since your little one is still so young I recommend you do the switch gradually. Try a of couple bottles with 25% of the new and 75% of the old. If that works well then switch to 50/50 and after that 75/50. If everything goes well then you should be at 100% in a day or so. If the Gerber Soothe doesn’t give you enough improvement with the gas I recommend you try probiotic drops.

      Hope this helps your little one!

  48. Hi…

    My LO was having a terrible time throwing up and was also very gassy.  We decided to switch from Similac Sensitive to Gerber Good Start Gentle.  She seems to be a little more gassy and she spits up just a little – unlike the projectile issue we had last week while on the sensitive.  She has no fever, no runny diaper, just mostly gassy.  The doctor gave up the Gerber Soothe drops.  We also add one teaspoon of prune juice to her bottle per day.  I have Colic Calm for the gas as well.

    We are hoping that the probiotics in the Gerber will help her digestive system and may also help with the occasional constipation.  FTM here and I’m 46.  This isn’t easy! I can’t stand to hear her strain but throwing up through her nose and mouth was far worse.  Will I survive this stage?  🙂  Yes; I will but it is a little scary at times.  Am I on the right path with the formula.  Is it a little normal for them to go through a transition period when changing formula?  Should I do a ration with the two?

    1. Unice,

      Good for you, first time mama! You are doing so well.

      Yes, it is normal for there to be a little adjustment period. However, the probiotics should help and it’s great news that the throwing up has gone away already! If she continues to have trouble with gas you may consider probiotics drops as well. It’s something you could talk over with your doctor.

      Regarding the best way to switch from one kind of formula to another we have a helpful article about how it’s done. Since Similac Sensitive and Gerber Good Start are both dairy based it’s just fine to switch from one to the other.

      Keep up the good work! Seems like you are a natural.

  49. My LO is 4 weeks old. I had him on Similac Advanced and switched him over to Enfamil Gentlease due to fussiness. After one week on the Gentlease, he has had really bad gas pains. I felt he did better on the Similac Advance, so yesterday evening I switched him back over to that (cold-turkey). He BM’s seem normal, but he just started having crying fits, so I don’t know if he’s uncomfortable. Should I have mixed the two formulas instead of switching cold-turkey? Since I just switched it less than 24 hrs ago, should I go back to Gentlease and start weaning?

    1. Jenna,

      Why don’t you mix the two formulas 50/50 and see if that helps his little tummy. If he seems to be settling then you can do a 75/25 for a couple of bottles. If he is still doing fine then you can switch him to the new formula 100%. Hope this helps your little guy!
      Also, if the gas continues you might consider giving him probiotic drops. This helps with gas in the intestines.

  50. Help! My Little boy 3 weeks old has been gassy/colic/fussy/constipated pretty much since bringing him home. We started him on enfamil A+ and he cried for hours and horrible gas we then switched him to Enfamil Gentlease and he got a little better but still cries right after he eats a bottle and arches his back, lots of gas, and constipation on and off. I then switched him to nutraimegen formula cause my daughter was on it and she did amazing on it, but it was like the reverse effect on him. He began to projectile vomit, loose stools, and cried even more! We then went back to gentlease cause we do not know where to go from here! Any suggestions?? I am thinking of trying Good start soothe or gentle not sure which one I should switch too also even if I should switch! I hate playing formula switching game but I can’t handle seeing my LO one in so much gas pain and crying for hours on end! Also can’t breastfeed due to not being able to produce milk…mommy guilt is kicking in so any suggestions would help! He is also on a really good probiotic that I add into his bottles. Also in Canada so not sure if gerber soothe is available here so what formula would t be up here

    1. Candace,

      I know it can be such a frustrating process to search for a new formula (kind of like searching for a new home!) but hang in there. I do recommend you try another brand and Gerber Good Start Soothe is a good one. I’m sure the probiotic you’re giving him is helpful for his little intestines. Take a look at this article about Hypoallergenics so you have a better idea what your options are (and what to talk over with your doctor) if the Good Start doesn’t work for him. One other thing, Amazon Subscribe and Save is one way we recommend saving money on formula if you have trouble locating Gerber where you live.

  51. Hey there,
    I was wondering if switching from enfamil gentlease to just regular enfamil will upset my babes stomach? We have 3 cans of the enfamil and don’t want them to be wasted.

    1. Ashley,

      If they are from the same family (i.e. both dairy based) it should be fine. If you can though, I would recommend mixing with the old 25%/75% at first to ease your little one’s tummy to the change.

  52. My son is 8 months old, 6 months adjusted, and was exclusively breastfed until 6 months. I started supplementing at 6 months with enfamil gentle ease and he did awesome with no problems at all. I recently just got WIC and they only offer Similac for formula so I figured I would just try it out since he didn’t have any problems with enfamil. I did slowly transition him and he had been on it for 3 weeks but as soon as he stared the formula he was constantly plugged up with a runny nose. It would get a little better and as soon as he had a bottle it would go right back. He always was crying all the time and he never is like that. I tried to wait it out and see if his body would get used to it but it just seemed to get worse, so a couple days ago I switched him back to Enfamil Gentle ease. He is less stuffed up and seems to be doing better, so could he just be allergic to the similac brand all together or why would this be?

    1. Charlie,

      Which Similac formula did you use when you switched him over? The Similac Sensitive would be comparable with the Enfamil Gentlease. Take a look at this article for a good list of the major formula brands. This is a helpful resource when you need to do some switching around. The Similac Sensitive and the Enfamil Gentlease are comparable because they both have the milk proteins partially broken down which makes them easier to digest (you can read more about this here). If Similac Sensitive is the formula you tried then you can assume that the brand is just not a good fit for your little one. Sometimes that happens! If that’s the case then I would stick with the Gentlease. Hope this helps!

  53. My little guy will be 4 weeks old this Monday. He was on similac, but we changed him to the Kirkland brand formula with the omega 3’s & 6’s. He was fine after fully switching the first 3 days, the days 4 & 5 he started having bowel movements that were more firm and crying with the passing of a bowel movement. I’m wondering if it IS in fact the formula (they are so close in the nutritional factor list, off by a .2 on most things) or if his body is just adjusting to the new formula. I would hate for him to be constantly changing formula. Do we give it another week and do bicycle legs/warm baths or should I call it and change him to something else?

    1. Britney,

      Oh, I know how un-fun constipation can be for little ones! We do usually recommend that you give the new formula a week before you decide one way or another. This will give his little body the time it needs to adjust if it’s going to. In the mean time, talk to your doctor about adding prune juice to his bottles. It can help with the constipation. Just make sure you get the dosage from your doctor cause it’s important to get that right. Hope that helps!

  54. Anyone have any advice on this it would be greatly appreciated. My 5 month old is on gerber soy about 5/6oz every 4/5hrs I know this is suppose to be pretty good stuff but my concern is that if she is not being held, bouncing in her seat, eating or sleeping she just screams and cries. I don’t know if I need to switch her formula or what. If I switch her formula I do not know what to switch it too. Anyone have any ideas? I go see her pediatrician tomorrow so I plan on asking her just thought I would see if any other mommies have any ideas or thoughts.

    1. Cassy,

      I am sure your pediatrician will help you with this but it does sound like switching formula would be a good idea. Is there a reason she is on soy instead of dairy formula? If you can switch back to dairy I recommend something gentle like Gerber Good Start Soothe. Just make sure take your time when making the switch. Try the 75%/25%, 50/50, 25/75 method. Start with 75% of the old and 25% of the new formula. Do this for a couple of bottles and if things are going well you can move on to 50%/50% and so on… I also recommend you try probiotic drops. These can really help their little intestines work better so there is less gas.

      Hope this helps your little one!

  55. So glad I came across this site!

    Just looking for some guidance. I have little boy who is 3 weeks old, and he has been on Similac Advance since birth as I was unable to breastfeed. Recently I’ve noticed that after almost every feeding, he seems to be very fussy, almost in pain, and just cries and cries. He never spits up, but does pass gas. I’m concerned about his bowel movements as he only has 1 every 1-3 days. When he does have them, they aren’t firm, but more on the watery/soft side and are very large and very ‘explosive’. They are also a chalky green/grey colour. I’ve decided to try and switch him over to Enfamil Gentlease, but am nervous after reading some of the other Moms  experiences. My plan is to switch him over tomorrow with 3 parts Similac and 1 part Enfamil Gentlease, and increase daily. Am I doing the right thing by trying to switch him?

    1. Kate,

      It is probably a good idea to try something different and gentle. Are you working this through with your doctor?

  56. My 2yr old daughter is strickly formula feed do to feeding issues. Shes on gerber gentle after being on alumintum. Ive tried swirching to the walmart brand sensitive but she constipates instantly. Is there another brand i can try thats cheaper. I cant find the wslmart brand tender which they say is comparable to gerber

    1. Carina,

      First, let me direct you to this article about how to save money when you are buying formula. I hope this might help. I also recommend you consider adding probiotic drops to her routine (you might want to consider something a little more potent because of her age, talk this over with her doctor). It can help with tummy troubles. If the constipation continues you can also talk to your doctor about adding prune juice to her bottles. Just make sure you get the appropriate dosage from your doctor before you give it a try.

  57. I was told by my doctor to switch my 4 week old son to a soy based formula because he was having a lot of gas and just being very fussy acting like he couldn’t poop even though he was having regular bowel movements. It’s been one day and he has diarrhea and lots of gas and just wants held. I didn’t gradually switch and I’m wondering if that is what the problem is. How long does it take to know if the new formulaishelping?

    1. It may take him a while to adjust to digesting the new formula. I would give it at least week – but don’t hesitate to call the doctor if you don’t think he’s improving. You may also find using gripe water and probiotics may help. (Ask your doctor, of course, before using them.) Gripe water can help with tummy gas, while probiotics can help with intestinal gas. Hope this can help!

  58. Would it be okay if I give my baby a few bottles of enfamil gentlease until we get her regular formula ?
    She usually drinks enfamil infant.

    1. Daianny,

      If the formula is in the same family (i.e. dairy, in this case) it shouldn’t be a big deal to use a different one, especially if it’s the same brand.

  59. Hi Heather! I’m hoping U have a few words of wisdom for this. My pedis office Is closed on the weekend 🙁

    We are trying to switch our 6 week old son who is a twin over to formula from fortified breastmilk with elecare 22 cal. He was diagnosed with a milk protein allergy when he was in The NICU a while back. We recently tested his stool for blood and found some and decided to go to formula bc I can’t see myself being dairy and soy free. We started with a full bottle of elecare ONLY and he took it ok but vomited. We realized we should do it slowly so we have been doing some of the old formula mixture with the new sole elecare mixture. The first Time we did that and since he takes About 8 sucks and then pulls off the bottle and screams and kicks his legs and cries. He burps and then is ok. But he won’t finish the bottle though and still seems starving after he cries and pulls awsy from bottle. Does he just hate the taste now that there is more elecare and less breastmilk?

    We also need to switch sister from breastmilk fortified with neosure to full neosure. know it’s Prob not best to do this all at once. Both him and sister have some acid reflux too. What are UR thoughts? Thank you

    1. Carol, I’m sad to type this, but this really is above my pay-grade to answer. It sounds like there a lot of medical issues that need to be balanced here, so I would refer you back to your doctor – who is expert #2 (Parents being #1 of course) and can see how all these things play together. In this special case, I’m wondering if you should forget gradually switching, and just go from breastmilk to elecare – especially since you’re not off dairy and soy (I’m with you, I don’t know if I could do that either!). Ask your doctor about that – most pediatrician offices have an after-hours call line you can use to talk to a medical doctor after hours. I would totally use that option.

      Also, ask him about using probiotic drops for the twins. Those have recently been shown to help with reflux babies, and could also help with the gas problems.

  60. My son is almost 9 months and drinks gentlease around 4 bottles a night that are 6 oz each. Do you think I should switch to gentlease step 2 for toddlers for ages 9-18 months? Do you think it will keep his little belly fuller longer?

  61. Hi! My son is 7 months old. For the first 4-5 months he was on Enfamil Newborn RTF and then Infant ready to feed. He wouldn’t take powder possibly because I think he had silent reflux. I think the thicker RTF helped. He has had Diaherrea for the last 2 months. The dr ordered labs but also told me to try switching formula. After reading your articles I was going to start by trying the Good Start. Is that what you would recommend? Or the Good Start Soothe? I am concerned his reflux may act up again. Thanks for your help and for writing this blog!

    1. April, you have three choices here…

      1. Choice one is to switch him to a hypoallergenic formula using the steps above. Hypoallergenics are more expensive, but studies have shown they are helpful with refluxing babies. Read more about hypoallergenics here.

      2. Choice two is to use a thickened pre-mixed formula that is specifically for acid reflux babies.

      3. Choice three is to use something gentle like Good Start Soothe or Similac Total Comfort and then add a little rice cereal to thicken it by yourself. Your doctor can tell you exactly how much to add.

      I would pick one of these options that you think may be a winner, talk to your doctor about it, and then give it a try for a few weeks to test. 🙂

  62. Hello,

    I’m a new father to a 4 day old daughter. When we were in the hospital her BMs after breastfeeding were perfectly normal. However, after we were discharged, things changed. Her mother has yet begun to get her milk in so we can only squeeze half an oz out of her. Thus we have been mixing what we can get with Similac Advantage Stage 1: Birth-12 months. Is this bad? We feed between 1-2 oz every 2-3 hours. She doesnt fuss or vomit after but since mixing them, her BMs have gotten rare, she seems to struggle, cries…i feel so bad for her. I’ve tried the qtip but was only succesful 1 out of 3 times getting about a regular amount. Now, when she does have one of her rare BMs, only a tiny bit comes out. Neither I nor the mother are lactose intolerant. Could it be the Similac?? Mixing them?? Or might it be a constipation issue I must see the pediatrician about?

    1. Justin,

      When your little one is this young you really do want to take all feeding/wetting/pooping issues to the pediatrician!

  63. My daughter is 9 weeks old now and she has been fighting gas issues bad and we switched her about three weeks ago to the Gerber soothe and at first it seemed like it worked along with the Zantac they gave her but since then she has gotten constipated ALOT. We had her on Enfamil at first then went to the similac sensitive and now the doctor said gerber soothe and it still is not working for her gas and the constipation has become an issue. Seems like an issue since the Zantac. I was thinking of doing the Similac Alimentum to try that for the gas, constipation and severe crying but it makes me nervous. I do go to the doctor on Thursday and want to mention the Zantac but I am so worried about them doing lab work. Do you think it is okay to switch to that formula or should i wait until Thursday?

    1. Ashley,

      Call your doctor and ask if you can add a little prune juice to your daughter’s bottles. The doctor’s office should be able to help you with dosage. Also, probiotics can really help with gas in the intestines. I recommend this brand (it can also be added to her bottle!).

  64. Hi there, so I have a 6 week old who is fully formula/bottle fed. He was on good start probiotic but was extremely constipated the whole time. The only time he would have a bm was if I helped him with a qtip. Did that a couple times but I didn’t want him to get used to it so I stopped. He was miserable the whole time he was on it and kept whimpering constantly trying to push but most of the time nothing happened. His face would go red and he would push and cry alot. Sometimes scream. I see decided to switch to enfamil gentlease a couple days ago… By using your switch advise. Since, he seems that he’s hungry more often and is becoming harder to put to sleep. He still seems to be pushing alot and sometimes cries but not as bad as he was. (He always even on the old formula and new. seems to have bad gas and tummy pains. Never seems like he has a good sleep, is constantly waking and trying to Fart or poop and whimpers and sometimes cries.)
    With this new formula he was able to have a bm yesterday on his own which a much softer. I’m almost out of my formula and thinking of going to parents choice gentle cuz it’s cheaper. Is it okay to just switch on over? He’s only been on gentlease for maybe 5 days now. And or I’m also thinking he may have a lactose issue. I know my husband has problems with dairy but I really don’t know if my LO does or not. I’ve been tossing between the gentle and sensitive formulas but I’m not too sure what to do.

    1. Amanda,

      We recommend you try the new formula for a full week before trying another. As long as the two formulas are in the same family (in this case, dairy) you should be able to switch right over. However, you might want to try easing in a bit just because your little guy has history with constipation. You could try the 75/25, 50/50, 25/75 approach where you start with 75% of the old formula and only 25% of the new and after a couple of bottles up it to 50%/50%. If things are going well after a few bottles try the 25% old and 75% new and then after a few more switch to 100% of the new.

      Since you suspect a lactose issue with your little guy I would try the Parent’s Choice Gentle if you decide to switch.

      Also, talk to your doctor about adding a little prune juice to his bottles to help with the constipation. Your doctor can help you decide on dosage (it’s important to get this right!).

  65. Hi heather.

    My son is 4 months old and he is been on similac advance since the day he has been born and has been sneezing. Few weeks into it soon after he drinks he gets congested and coughs. Around 6 weeks he started spitting up and sometimes projectile vommiting. So the doctor put him on Zantac which helped for few days with the spit up but the congestion and cough and has eczema bus symptoms still persists about w month ago we switched to similac for spitup cold turkey and did well but still projectile vomited some of his bottles and and at the end of March he had rsv. So now he is still spitting up and coughing and congested doctor ran a respiratory panel and he doesn’t have any viruses. So I decided to switch to soy. Yesterday I did it cold turkey first bottle went great but had terrible gas half an hour into gas drops fixed it. second bottle he ended up vommiting on me. So this morning I decided to go back to his spitup formula and will follow your 1:3 directions to see if I can get him on soy. My husband his mom and his cannot do milk so I am suspecting s milk allergy but the doc doesn’t want to test because there is no blood in the stool. But all his symptoms do point to that.

    1. Karen,

      I recommend you go ahead and insist on the test. Sometimes the blood in the stools is too small to see (your doctor should know this). I think you should go with your mama instincts on this one. We just published a post about this very thing…

      Why don’t you try something very gentle like Gerber Good Start Soothe (very small proteins and it also has probiotics that will aid in digestion). When you do the switch try the 75/25, 50/50, 25/75 approach where you start with 75% of the old formula and only 25% of the new and after a couple of bottles up it to 50%/50%. If things are going well after a few bottles try the 25% old and 75% new and then after a few more switch to 100% of the new. This gentle approach will help your little one’s tummy adjust.

      If you find out that your little guy does have a dairy allergy then talk to your doctor about the possibility of switching to a hypoallergenic formula. In the meantime, I also recommend this article about dealing with dairy allergies.

    2. Heather, We started soy yesterday doing the 1:3 ratio and so far we are liking what we saw… he was totally different he wasnt fussy and screaming in head off and looked in pain… he has 6 bottles so far using the soy and spit up formula and looks like his eczema doesnt flare up a lot after he eats… he doesnt look like he is miserable.. the next bottle i give him i will do the 2:2 and see how does it go… his first poop yesterday night was Dark green and sorta peanut buttery texture and then next poop this morning was dark green not as peanut buttery… he next poop was not that runny but it was mixture green and brown and looked mucousy. But hasnt spit up a lot of what he has taken.. the last bottle he did a bit but not that bad…my doctor has told me to try soy so doing that way but she doesnt want me to do alimentum… he is going to be having a swallow study on wednesday to see about the reflex but at this point its looking more like a allergy rather than reflux.. when he was at the doctors all our stars aligned and i had to change a poopy diaper so his diaper had a bit of mucousy but she asked if he always has it and i said and she said its normal… but he is still coughing and congestion isnt that bad still gets congested soon after eating i think i am seeing some improvements.

    3. Karen,

      I’m glad to hear things are improving! Give the soy a week and keep an eye on his diapers. It really does sound like a probiotic would help him too. Try these drops for a starter. It should help his little digestive system and his diapers have less mucous. He probably just needs a little time to heal!

  66. Hi. We were on similac advanced until 12 weeks. We switched because she started screaming after 2 oz and burping and would not eat anymore. This went on for 2 weeks until the Dr recommended soy and said it could be a milk allergy or reflux. So we tried that. After 4 days I thought we were back to normal but that only lasted 5 days and now it seems like the past 2-3 days were going back to not wanting to eat and being upset about it. She’s not losing any weight. He said we would try hypoallergenic after soy. What formula would you recommend. Nyicu nutritionist said we should have tried sensitive first, but would that even help now if she’s not agreeing with soy? He said we went to soy because it doesn’t have the milk proteins. Please help us.

    1. Toni,

      Actually, before you go down that road, I recommend that you try another brand. Sometimes switching brands really does the trick. Why don’t you give Gerber Good Start Soothe a try. It’s very gentle (the milk proteins are very small) and it also has probiotics that aid in digestion. When you switch from a soy based formula back to dairy though do it slowly. Try the 75%/25%, 50%/50%, 25%/75% approach. So, start with 75% of the old formula mixed with 25% of the new. After a couple of bottles switch the to 50%/50% and so forth. Give the new formula a good week before you decide if it’s right for your little one. This article talks more about how to do the switch.
      Just a FYI, I recommend that you take a look at this article about hypoallergenic formula so you have a better idea of how to talk this over with your doctor if needed.
      One more thing, here’s a great article comparing all the major brands of formula also for your information.

  67. Hi! My baby is almost 3 months & has been through 5 different formulas! She was first on similac advanced then soy then sensitive and sensitive worked for the longest and out of no where she started to fuss and spit up and not poop. Now she’s on similac alimentum, it’s working for her she’s now pooping and fussing way less but she doesn’t like it at all she will not drink her whole bottle. She went from 6oz every 3-4 hrs to 3oz every 3-4…I’m lost! She’s been on reflux meds since she was 2 or 3 weeks.

    1. Kyra,

      It’s not fun to have to search and search for the right formula for your baby! However, this site has a lot of information about formula so I hope it will be a help to you as the search continues. Hang in there! You will find the right one, just remember to give each new one a good week before you decide and if you are switching families, as described in this article, do it slowly (75% of the old and 25% of the new to start. After a few bottles of that, 50%/50% then 25%/75%. If all goes well you can then switch to 100% of the new).

      I recommend that you check with your doctor about switching to a different brand, something that is very gentle like Gerber Good Start Soothe. Sometimes switching brands can really help. In the meantime, take a look at this article that contains a handy list with all the different major brands of formula. Also, this article can help you as you talk with your doctor about whether your little one really needs a hypoallergenic formula at this time.

  68. I have a 1month old baby and I have a  question I was giving my baby simalac but was always vomiting and constipated. i changed it to soy but still vomiting (not as much) and constipated, doctor switched it to allumnton and she has beed vomiting more and very fussy.  What  can I do to help the switch.

    1. Dee,

      The first thing I would recommend is switching to a different brand. Sometimes switching brands can really help. Why don’t you try something gentle like Gerber Good Start Soothe? When you do the switch start with 75% of the old brand and 25% of the new. Do this for a few bottles then try 50%/50% and after a few more bottle (if it’s going well!) try 25% of the old and 75% of the new. If it’s still going well then switch to 100% of the new. This might take a couple of days but will help your little one’s tummy adjust. If you try the new brand and it’s not working well after one week then talk to your doctor about a different brand of a hypoallergenic formula. This article can help you if you end up needing to head into the land of hypoallergenics.

      Hope this helps your little one!

  69. ok, to start off, I think you are so wizened and helpful, and I’m so thankful to have found this website! Secondly, my baby has been on normal infamil infant formula for 7 months and when I took her to the Dr. For a cold I asked for a sample of the infamil soybee sample thinking that the lack of dairy protein would help reduce the mucus production, well I switched her cold turkey for a week and then after that one can of infamil soybee formula was gone I switched back cold turkey yo her normal infant infamil formula. That first day she spat up after every feeding and so the next day I did a 1:1 ratio of both types of formula bur she has been painfully constipated all day, how do I get her back to her normal formula with out messing her tumy up any further? Thank you sooo much!

    1. Rachel,

      So glad Heather’s articles have been helpful to you! Don’t you wish they DID send a complete “How To” manual home with each new baby. Then we wouldn’t have to learn anything by trial and error!

      I recommend you do the 25% of the new /75% of the old, 50/50, 75/25 approach. You can take a couple of days to do this. Use each ratio for a couple of bottles before you go to the next one. You also might want to give her a little extra water by itself just to help her body deal with the constipation. If this doesn’t work you should talk to your doctor about adding a little prune juice to her bottle. Make sure to check dosage with your doctor before you try it. Or, if she will eat them, you can feed her some baby food prunes (my little one is the same age as yours and hates them 🙂 )!

  70. Hi, my baby is almost three months old and he’s having difficulty making bowel movements. In the beginning I used enfamil gentlease and it worked great. After two weeks I noticed my son wasnt making any bowel movements. We decided to switch him to good start gentle and the bowel movements became normal again. Now we are seeing the same thing. He is having difficulty going to the bathroom. I have to do baby exercises to get the poop out. My pediatrician told us to give him 2 oz of water in between feedings to help loosen his stool, but it doesn’t seem to be working. Any advice?

    1. Diane,

      Oh, it’s tough to see your little one try and try and have such discomfort too! I recommend you talk to your pediatrician about adding a little prune juice to your little guy’s bottles. Talk to your doctor about dosage before you try since it’s important not to add too much.

      Hope this does the trick!

  71. My daughter was on breast milk for the first 5 months of her life until her pediatrician diagnosed her with a cows milk protein sensitivity. She then went on neocate and has been on neocate for 4.5 months. We battled constipation on and off since being on the formula. I was giving her miralax and probiotics daily until she was regular. She’s been off the miralax for a month and having regular BM’s and everything has been great. As per the pediatricians advise we recently started her on nutramigen to see how she would react and to hopefully be able to introduce cows milk soon. Its been two days of half neocate and half nutramigen bottles and now she is horribly constipated. Full out crying in pain and shaking this morning trying to go. Did I go a bit too fast making the notes half and half? Should I add less nutramigen and give it a week and see how she does? So hard seeing her in this much pain.

    1. Bridgette,

      Yes, go with your mama instincts on this one! We always recommend 25% of the new formula with 75% of the old to start. Do that for a couple of days and see how she does. If constipation starts in then that’s her body telling you she’s not ready for the dairy.

      Also, we just released an article about the milk protein allergy. This might be helpful for you as well.

      Hope she’s feeling better soon!

  72. I have a one month old and he was born a premie with being on Enfamil newborn. When I took him to the doctor, my pedi recommended similac advance(which I thought would be super harsh on his tummy, but did so anyway because I am a first time mom), he did not handle the formula well at all and 2 weeks, the doctor decided to try Similac Alimentum. 2 weeks in he developed symptoms I didn’t even see with the similac advance. All which refer back to silent reflux. He screamed between bottles, after bottles, screamed in his sleep and it was heartbreaking. I told my pediatrician, and she did not seem concerned because she ordered an ultrasound which showed no harm and because he was gaining weight she turned away from my concerns!
    My mommy mode quicked on and I started Gerber soothe and it made slight a difference; however, I can still see the reflux is causing him major discomfort. we cannot get to a specialist until a month and I want to wing him into the Enfamil AR; however, I just started the gerber soothe and I can already tell the symptoms will just keep rising. Any advice? I’m so tired of my child screaming and I know he’s in pain. Please help 🙁

    1. Cassandra,

      First of all, you are doing a GREAT job being an advocate for your baby. Taking care of a premie is a lot of work! You’re doing so well with all the many factors to consider. Secondly, it concerns me that you do not feel like you are being heard by your doctor. It’s very important that you and your doctor be on the same page. I encourage you to consider getting a second opinion somewhere else.

      In the meantime, while you are still waiting for the appointment with the specialist, why don’t you proceed as if your little guy does have reflux (not unusual for premies, by the way).

      Here are the things you will want to consider:
      #1) Consider trying a thickened formula or possibly a different brand of hypoallergenic formula. You can read about hypoallergenics here.
      #2) Make sure he’s sleeping on an incline – instructions found in this article for how to incline your crib mattress. Or, have you tried a Rock N Play?
      #3) Talk to your doctor about probiotic drops. Recently studies have shown they can be helpful.
      #4) In cases like this, medication may be your best chance of getting a handle on it. Zantac is usually the first drug prescribed – it makes the bile less acidy. It can be prescribed and used for a long period of time. Prevacid is usually the next thing they prescribe. It actually reduces the amount of acid being produced. Because of this, it can only be prescribed for a short period of time – which is why it’s usually the last resort.

      Keep up the good work and trust your mama instincts. You don’t have to second-guess yourself because you are a first-time mom. YOU know your baby best! Hope this helps!

  73. Hi..my baby is almost 8 weeks now..i had difficulties in breastfeeding in the beginning so i started him on similac anti-colic from day 1 ..then gradually i start to breastfeed but He was always vomiting after I give the formula very large amount nearly the whole amount of feed,add to that the abdominal gases ..from week 2 he was constipated like he just pass stool every 3 to 5 days 🙁 hard stool but no blood thanks god then i switch to aptamil anti colic and constipation when he was 4 weeks till now so the colic is much better but constipation is there so plz tell me wbat to do regarding constipation ?can i give him water? Thanks

    1. Fifi,

      I would talk to your pediatrician about putting a little prune juice in his bottles. It’s important to get the dosage right, however. That’s why you should talk this over with your doctor. Hope this helps your little guy!

  74. Idk if your still taking questions but thought I’d ask anyways 🙂 my 1 week old I started on enfamil gentle ease but she spitup almost after every feeding so here at her 1 week checkup she hadn’t gained any weight so Dr thought I should try soy formula so I switched to enfamil soy and she seems more hungry and less full with this and I didn’t know you should ease into switching but I don’t think she needs soy …idk what to do I’ve used similac sensitive with my first and we had no problems and wonder if I should try that I know every baby is different. I just want the best for my little girl but clueless on what to do

    1. Erin,

      Why don’t you try her with Similac Sensitive? Sometimes switching to another brand and a sensitive formula can make a big difference, depending on the child. I would not usually recommend switching to soy first thing so I think your mama instincts are right on that one. Do transition slowly when you make the switch (now you know, right?!).
      I hope this helps your little one. Congratulations!

  75. Please help! I’m not sure if what’s going on with my lo is normal… He is ten weeks old today. I tried breastfeeding when he was born but was only able to for about three days and felt horrible because I thought I was starving him because he was constantly crying and I would try to feed but it didn’t seem like he was getting enough. Anywho, the night we came home from the hospital, I was trying to breastfeed him again and he just seemed to be having trouble latching and not getting enough. We had gotten a sample of Enfamil Newborn and I told my husband let’s just try this and if it seems to work, we’ll just formula feed him, if not I’ll call the doctor right away. We gave him two ounces, he slept “like a baby”for the the first time! We decided to keep him on formula from that moment on. He did great with it for about a week. Then the second week he started screaming during feedings as if he was in pain, I felt horrible 🙁 A friend suggested Earth’s Best (it’s organic). We got the one for sensitivity. It seemed to be working great for about two weeks, then the screaming pain sounding cries started again 🙁 His poop also seemed to be really thick and not as soft as it had been with the Enfamil. I called his doctor and they suggested giving him gas relieving drops. They seemed to work off and on for a little bit but then after a couple of days just didn’t seem to work at all. At about seven weeks old, he also started to spit up a lot, which he had never done! At his two month old check up, I mentioned everything to his doctor and asked about switching formulas. She kind of dismissed everything I said and only focused on the spitting up part and suggested it was a volume issue and recommended going from 4oz every three hours to 3oz every two hours. We tried that for a few days, the crying continued but the spitting up slowed down a bit, not entirely. We decided to change formulas again, this time to similac sensitive. He’s been on it for about six days, he hasn’t cried at all during feedings but has been extremely gassy and they smell as if he has pooped (they didn’t smell that bad before). He mostly just has a little squirt come out when he passes gas. When he does poop, which is about once a day, it’s a bit watery. He hasn’t really spit up. Every now and then I’ll notice some tiny chunks in his mouth. He sleeps great through the night, anywhere from 5-7 hours. During the day, he only sleeps if he’s in my arms. If we try to put him down he wakes up and cries loud. His eyes also water a lot during feedings, is that normal? He’s been taking a vitamin D supplement since he was about 4 weeks old (his doctor recommended it). I know this is a lot of information, I just want to know if you have any ideas as to what could be going on with him. Should we try a different formula? I hate seeing him in pain, it breaks my heart. 🙁

    1. Olivia, the first thing I would do (if I were you) is to seek a second doctor’s opinion and ask about the possibility of reflux or silent reflux. Just to make sure. Some of these symptoms (with and without the spit up) are pink flags for reflux. I say “pink” because they aren’t a sure thing, but it’s something to mention and get checked. Besides, it sounds like you don’t feel too supported by your current pediatrician – that you don’t feel she’s listening to your concerns. THAT is a red flag that you should go and check in with a different doctor. It’s important that parents feel they are on a “team” with their doctor, and I’m not getting that vibe from your post.

      You’re doing exactly the right thing – asking questions and looking for solutions. He’s a lucky baby to have such attentive and caring parents. Keep your head down and keep pushing for answers – but also take heart that this current “this is what parenthood feels like” is temporary. It will get better, I promise. 🙂

  76. Hello, hoping you have some advice.  My son has been on Enfamil Infant since about 6 weeks when my breastmilk dried up(he is now almost 5 months).  He did well on it and seemed comfortable and happy but I mentioned to my doctor that he tended to have a blow-out once a day or once every other day.  She told me it was probably from too much gas and told me to switch to Enfamil Gentleease. He’s been on it about a week. He got constipated and we had to use a suppository.  Since then, he’s been going about once a day but his poop has smelled absolutely terrible and has been very dark. He has also stopped sleeping through the night!  I called the doctor and she suggested Goodstart Soothe but it seems extreme considering he was doing well on the Enfamil Infant.  What do you think?  I’m tempted to just switch back to Infant and do a little extra laundry.

    1. Carly,

      I agree with you, I think you should follow your mama instincts on this. You may also want to try Probiotic Drops too though. They will help with the gas in the intestines and hopefully make a difference in the blow out situation.

  77. I should also mention…

    1. He had some dryness on his cheeks that seems to have gotten worse (but could just be our NENortheastern winter and my hypochondriac nature)
    2. He drinks the formula but not as much as he drinks the breast milk. Before he was drinking 3.5 oz per bottle. Now when he has formula he drinks 3 oz, but then will drink 4 or 4.25 oz of breastmilk at the next feed.

  78. Based on previous post…you say give formula a week before switching…

    I have been slowly transitioning my 11 week old from breast milk to formula. We did it differently than your site suggests (because I just found your site!) – he normally got 7 bottles of breastmilk a day. On days 1-3, I gave him 1 bottle of Enfamil Gentlease; on days 2-5 he got two bottles…tomorrow is day 6 and he will start on three bottles, etc.

    He is generally a gassy baby and has mild reflux. Both things were waking him up from sleep, crying and straining. Reflux meds had decreased these wake ups. But I have noticed the last two days he has been waking in his sleep again. He seems to be straining more to poop. And the gassiness is back.

    Also before we started the transition, he was down to 2 GIANT poops a day. The last few days, he poops 2 medium sized times.

    Since my current transition plan is super slow
    …do you suggest I speed it up And see how baby does? Do you think I should try a different formula?

    1. Ed,

      Why don’t you switch to the 25/75 50/50 75/25 plan instead, do this over the next two or three days. If you have a reflux baby I highly recommend probiotic drops. This will help with the gas in the intestines and also with digestion (to help him be more regular!).

      After you try the probiotic drops then you can decide whether or not to try a different formula. Take a look here for a complete list of the major brands of formula. This will help if you decide you do need to switch again.
      Hope this helps!

  79. My baby is 9 weeks old. He was on Similac sensitive since birth. I am currently on WIC.. They only offer Enfamil so I got Enfamil gentlease.. I started it 2/6/15 4 oz bottles 1 scoop of each kind. He seemed to being okay with it. The last 4 days I have been doing just the Enfamil gentlease. The last 2 days..He had very watery stools dark brown and green a few times and then it turned normal color yellow but it looks a lot thicker than normal. He has had a poopy diaper every diaper change. Before it was only 1-2 x day. He’s is always pushing and barely anything comes out but there’s some. He’s crying now as he’s is pushing which he didn’t do before. His bum is so red now the skin is bleeding. I have used the butt paste on it. I called the doctor they said his body is getting used to the formula to keep using it.. It just seems like it’s not getting better and he is in pain. They say those formulas are like Pepsi and coke but I feel like it’s not going well. He is not vomiting and doesn’t have a fever.. He has been more fussy as well and woke up 2 x last night crying while pushing 🙁 I don’t know what to do.. I am going to the doctors tomorrow I have a feeling they will tell me this is normal.

    1. Heather,

      Sorry to say it, but I think you need to find a different formula. We recommend that you give a formula a week before you decide for or against it. You have given it more time than that. Some brands just do not work for certain babies. Your little one needs a formula that will work for his little body! Check with your doctor and see if they have any samples of the Similac (that worked for him, right?) and/or coupons. Also, take a look at this article about how to save money on formula!

  80. My five month old has been using similac alimentum at the suggestion of her dr because she was colicky and would vomit. The dr said now it would be ok to try her on something else. I introduced similac total comfort in the way you suggested. Today is the beginning of day three ( I still mixed last few bottles because we still had formula) and now her poop is harder and not much came out. Lit is usually like pudding and she goes one big time sometimes two. Should I stop using the total comfort? Thanks in advance.

    1. Sara,

      First, you should give her body a little longer to adjust with the new formula (not fun when constipation is involved, I know!). She really needs a week before you will have an accurate idea if this formula will work. In the meantime, consider adding a little prune juice to her bottle. Check with your doctor on the dosage. Also, I recommend trying probiotic drops. They help with digestion and specifically address gas in the intestines. If she has struggled with colic in the past these could be a help to her.

  81. Please help!!! My daughter is 7 weeks old and has been taking similac supplemental for 3 weeks she has been constipated for over a week now. We have tried karo syrup, prune juice, and apple juice. Now we are having to use suppositories. Her pediatrician recommended trying different formulas my husband an I are clueless. We having been trying similac for discomfort for 2-3 days now she has starting throwing up. Her appetite has been slowly decreasing for over a week. Usually she would take 3 1/2 oz now I can hardly get her to take 2. She would eat every 3 hours now she may go over 4 hours an still take no more than 2 oz or so. What should I do ?!

    1. Kyleigh, firstly, call your doctor and let him know (if you haven’t already) that you’ve noticed a decrease in her appetite. He/She will want to know that.

      Regarding the spitting up – does it happen immediately when she eats? or 20-30 minutes afterwards? Does she seem more irritable 20-30 minutes after eating? I’m just wondering if there might be some reflux going on here, which would make her not want to eat. Ask your doctor about that – he can share symptoms and give her a physical exam. Perhaps give the Good Start brand a try? I’d start with Gentle and see if that helps with the constipation.

      Here’s the good news: You are attentive parents. You are asking good questions. She is well cared for, and there are answers. Asking good questions is the first step in finding them. You’re doing exactly what good parents do. Well done, friend. Hang in there. (hugs)

  82. My daughter just turned 1 on Jan 19. Since yesterday I started using Enfamil A+ for 6months – 18months babies after having used Enfamil 0 – 12 months for the past year. Since I switched, baby wakes up at night screaming, also has poop, which she never used to do. And it takes hours before she goes to bed. It has only been 2 days that I switched. Should I look into something else or wait it out. Thank You.

    1. Arusyak,

      Oh, you should definitely use your mama instincts on this one! Usually we recommend you give the formula a week before switching but if you can tell that your little one is in pain… Perhaps you should give the Enfagrow Toddler Transitions Gentlease a try.

  83. Ok my 7 week old son has been on Similac Advance since he came home from the hospital. I want to try switching him to Similac Sensitive. Should I introduce it slowly or since it’s the same brand will it matter?

    1. Kayleigh,

      The question you want to ask is, are they from the same family, are they both cow’s milk based in this case? Since they both are based on cow’s milk you can just switch over. If you are concerned about doing that though you can always use the 75%/25%, 50%/50%, 25%/75% method to switch over a couple of days. Also, just for your own information, Heather has a terrific, all-inclusive article listing the major formula brands. You can use it to reference as needed. Hope this helps your little guy. Congratulations, by the way!

  84. My baby is 1 month and 22 days she was on BM for a week and a half she tried the reg similac but threw it up. then i switched to formula similac sensitive she did fine for the past 4 and a half weeks she was doing awesome!she was so calm and pooped 3-5 diapers during the day and like 2 in the night . Then suddently she stopped pooping regularly for like 2 days she did half of the usual dirty diapers. Then she started pooping like squirts (mustard color) and poops everytime she feeds but like watery and it has a strong horrible smell im scared and nervouse now she cries and takws all night to finish 6 oz when she use to drink 12-14 i took her to the doc. And she switched me to isomil sensetive soy but im scared becouse shes been drinking it a whole day now and nothing seems to change she poops like 8 diapers a day and all painful and watery brownish mustard like. Her tummy was hard. …should i wait more…or should i just go back to similac sen.??;(( im so stressed becouse she now has a hprrible diapee rash! Like scraped red and moist i stopped with wipes and now wash her botton w warm watter. Then i pat dry and use desitin. Help!!”,(((((

    1. Thalia,

      So sorry to hear your little girl is having such trouble! I do hope you are keeping your doctor posted. You really need to keep a close eye on your little one because of the possibility of dehydration.
      If you can, let that little bum air dry to help with the healing. You may want to switch to Similac Total Comfort or Gerber Good Start Soothe. If these are not helpful then it may be time to consider a hypoallergenic. Heather has a new article about hypoallergenics that would be helpful for you to read.

      I hope this helps! Again, make sure you keep in touch with your doctor and take that little one in if you are at ALL concerned about the possibility of dehydration!

  85. Hey there! So I have my lo on nestle good start probiotic b (I’m in Canada) and that formula is 0-12 months but when he turned 6 months we switched him to good start probiotic 2 which from what I understood was suppose to transition them into solid foods better? I don’t know lol, but since he started on it he’s been so constipated. He used to go once a day/everyday while on the regular good start.. Although his stools were pretty thick and dark green (which is apparently normal for that formula). I have decided to switch formulas.. I want to go from nestle good start 2 to Enfamil gentlease. Which is a reduced lactose formula.. I myself am lactose so I’m wondering if that has something to do with it. Anyways, can I just switch over or do I have to transition? Like is that a different family of formulas or is it in the same mob?? Help!!!

    1. Rebecca,

      The good news is that both formula’s are based on cow’s milk so they are the same family (or mob). 🙂

      If you are feeling nervous about the switch though, you can always take a couple of days and try starting with 75/25 then 50/50 then 25/75 until you are 100% with the new formula.

      Hope it goes well!

  86. hello I have 2 moth old twins they have reflux that has being under control with prevacid and a carob bean thickner, we switch formulas from similac sensitive and similac comfort to alimentum cause 1 of them had some rash on head, face and chest, and because of the reflux, alimentum caused them colic we waited 72 hrs and It was the same but they were 1 moth old when they tried this formula, after that we switched to elecare for 2 weeks which  cause one of them throw up and both cry after feeding,  then we switched to neocate they have being on it for 2 weeks but they cry after each feeding, they cant sleep for hours only on arms, because they are very gassy and have colic!! we don’t know if aminoacid didn’t work if we should just go back to hypoallergenic formula like nutramigen or alimentum!!

    1. Erika,

      My head is spinning! It is such a challenge when you are trying to make two babies happy at the same time! Congratulations though, what a beautiful blessing to have two precious little ones.

      So, before you do anymore switching, I recommend you try probiotic drops for both of them. Probiotic drops help with gas in the intestines and might do the trick. Give this a try and feel free to get back to me (you should give it about a week).

  87. Our baby girl is 7.5 months old and started out on Enfamil Newborn. We graduated her at month 3 to Enfamil (yellow). She was diagnosed with eczema; however, the pediatrician and dermatologist did not think it was due to the formula, so we did not switch her. She began around month 5.5 having terrible blow outs in her diapers. So when she went in for 6 month check the doctor recommended switching her to SOY, which we did. The transition was smooth. However, now she is not sleeping at all through the night. There has been a lot going on, introduction of solids, teething, and her stools now not loose but very pasty. My husband and I have not had sleep in 5 weeks and looking back it has been since formula change. I am at my wits end. We have an 8 year old that was an easy baby. I feel like a first time parent. I don’t know if we should switch her back to milk based or wait this out.

    1. Tamara,

      First of all, congratulations that you were able to put two and two together about the formula switch and the lack of sleep. When I am short on sleep I can’t think straight at all!

      I would recommend switching her back to a milk based formula but something gentle like Gerber Good Start Soothe. I recommend this one because it also contains probiotics. Take a look at this article for suggestions on how to make the switch smoothly. I hope this will help you all get more sleep!

  88. I went through four different types of formulas, and my baby was fusdy and gassy on all of them. Then I switched to Parent’s Choice Soy. That resolved the problems. Now, my daughter just turned 1, and I’m about to start transitioning her off of formula. I need advice on whether to go with lactose free milk, or try regular whole milk.

    1. Jeanea,

      The first question you should ask yourself is if you saw any of the symptoms of an actual allergy when she was on formula based on milk protein. Take a look at this article, it should help. If there were symptoms of a milk protein allergy then you will need to consult your doctor before trying her on regular milk.

  89. Hi! First time mom, my daughter is almost 3 weeks old, born full term, no health issues that we know of  and we tried breastfeeding, a complete disaster, sadly. We put her on Enfamil newborn and she seems to like the taste just fine. However, I’ve noticed recently, but not after every feeding, she is extremely fussy and will cry with no soothing. Since it doesn’t happen after every feeding, I am not sure it is the formula or she wants more to eat, or to be held longer. She doesn’t poop everyday either which I know has to cause discomfort. She poops every 36 hours or so, sometimes sooner. It is usually peanut butter consistency although yesterday, I noticed it was more watery than last time. She also has to work at her pooping, she has to move, grunt, and lately I noticed her crying a little. She passes gas sometimes, but I am wondering if she has more trapped in her little belly that she can’t get out. Her spitting up has decreased if we hold her for longer in an upright position after feeding. She still spits up, just not nearly as much. I also think her spitting up is due to her crying so much sometimes after feedings. The past two days she is sleeping better on me or my husband, then when we put her down in her bassinet, she’s awake and cries. We tried giving her an extra ounce of formula, yesterday, she drank it no problem, then spit it up 40 minutes later, so I’m not sure if she was full or again, it is hurting her belly. She doesn’t have any hives, dry patches (other than where she was in the womb in liquid, the doctor said the patches were okay), red bottom, wheezing, or anything like that, just the random extreme fussiness after feedings sometimes, so I don’t know if it is worth switching her to another formula. Also, I wouldn’t know which one to switch her too. We’ve been to two peds and they are so wishy-washy on formula, my husband and I are scouring the internet for help.

    1. Elizabeth, those first few weeks are tough ones! You’re trying to get to know this little person, guessing your tushie off, and feeling pretty much lost. (Does it show that I’ve totally been there! – and you know you’ll feel that way with every newborn, no matter how many kids you have. 🙂 ) That said, it sounds like you and your husband are doing really well. (Even if it doesn’t feel like it!)

      I would make sure to bring this up with your pediatrician at the next well-baby visit to get his perspective (because his perspective is the most important one – other than yours). If it’s gas, you could try gripe water or gas drops. I would ask his opinion about the pooping. If you see any mucus in the poop, set it aside and let him know – he may want to have you bring it in for testing, to look for a virus or something.

      Usually the next step in formula-picking, is to go to a gentle version and try that for a while. So something like Similac Sensitive or Good Start Gentle would be a logical next formula to try out. I hope this can encourage and help you! You’re doing wonderful. Hang in there (and sleep whenever you can!) xo

  90. For the past three months, we’ve been mixing no fewer than three types of formula for every feeding. We have NEVER used one formula exclusively, and our girl is six months old and thriving. The reasons listed in this article for gradual formula transitions justify our methodology: her body is never dependent on any given substance. Clearly, not all formulas are the same. So if all formulas are different, we provide her with a more well rounded processed diet. “Switching too many times, too fast can really mess a baby up.”  I call BS. If I’m wrong, please reply so that my next three children won’t be messed up. Thanks.

    1. I don’t think you’re wrong, Chris. I think you’re 100% right about how that worked with your child, and that’s great. Some kids are highly sensitive to formula switches and can go through a period of colic/gas as a result of trying to adjust to too many different types of formula. Doesn’t sound like that was the case with your child – and that’s awesome. These are guidelines, meant to be adjusted by parents who know their own kids tendencies and family background. If it’s working for you, and your baby is thriving, then you’ve hit the jackpot – and disregarding this article is totally the right thing to do. 🙂

      Some parents, though, aren’t so lucky. For those parents I hope it can give them something to try, a little hope on how to help reduce the gas bubbles. Also, keep in mind that I only recommend switching formulas slowly if you are going from a hypoallergenic to a cow’s formula, or a soy formula to a cow’s formula (what I called “Formula families” above). Switching from Good Start to Enfamil usually doesn’t create many problems. Switching from Prosobee to Advance…that may cause issues for those kids with sensitive guts as their body tries to process those proteins because they come in different protein forms. Those are the situations that I recommend going a little slower and taking 2-3 days to switch. I hope this can help clarify the purpose and intent of the article. Thanks for commenting, I hope your other kids are as awesome on formula as this one is!

    2. Interesting. I appreciate the informative response and await the day we can all feed our babies actual food instead of mysterious beige powders.

  91. Hi, thank you so much for your helpful site. I have a 4.5 month old that I gradually transitioned from breast to formula after returning to work from materity leave. I’ve been through a lot of formulas with him because w few made him backed up and spit up. Now I’m trying to switch formulas because his Dr thinks his face rash is from an allergy to his formula we have him on now. The latest we tried before the Dr told us to switch was Similac sensitive. After that we tried regular Enfamil since he had the rash with the Similac formula. He still has a bad rash and now it’s progressed to a mild diaper rash too with the regular Enfamil. Should i try Gerber GS soothe? Like I said he seemed to have the same rash from Similac sensitive so not sure where to start. Thanks!

    1. Melissa,

      Yes, do give Gerber Good Start Soothe a try. Some babies do better with one brand over the other so it’s definately worth a try! The probiotics in Gerber Soothe could help his rash too.

  92. Hi Heather!

    Would Enfamil Gentlease and Nestle Good Start be very similar? If not, what is the difference?  Enfamil says it has less lactose than other formulas & partially broken down protein on the package, but Nestle Good Start doesn’t say anything about lactose, just that it has partially broken down proteins. (I’m from Canada, so I’m not sure if the Good Start name is different here)


    1. Jacqueline,

      They are similar…neither of them are low lactose. The reason they are gentle is because the proteins are so small. Also, both brands have probiotics which also help with digestion.

  93. My daughter is on enfamil a+, she is almost 7 months now so I was thinking of changing her to the enfamil a+2 recommended for 6-12 months. My question is can I just switch her over or should I gradually switch it?

    1. If they are both based on cow’s milk, you should be able to quickly shift. That said, if your baby is normally gassy, you may want to take 2-3 days just in case. 🙂

  94. Hi, thank you for your articles, they are indeed a great help for a new timer.
    My son was on BM for the first month, coming to the end I had to supplement it with S-26Gold, which mde him constipated, constantly crying as if he is in pain.
    Then on the second month we have changed to Frisolac comfort and for one week he was okay, but he constantly cry all the time, whenever he is awake. After feeding, burping, changing diaper etc. I notice now he is developing small bumps in the sking (looks like heat rash) and wheezes softly when I burp him. n

    1. Sarah, I would have a doctor look him over. Wheezing is something he’ll want to be aware of check over right away. Those might be signs of some reflux issue that needs to be addressed. Ask him specifically about Reflux and see what the doctor says. If it is some reflux, ask your doctor how to thicken the Frisolac a little with rice cereal – or if you should switch to a hypoallergenic like Nutramigen. Hang in there friend! Things will improve. Every day he gets a little bigger, and a little more able to handle these digestive issues!

  95. You have helped me in the past with my tricky little girl and I have yet another question. (Thank you) what makes a little one constipated? Is the formula not being digested? Is it to sensitive or not sensative enough? My little girl was on nutramagin for the first 7 months for reflux. She did great on it. Her dr recommended changing her formula so we could save for her college tuition (haha). Well I’ve had her on gerber soothe and now Similac sensitive. She has been so constipated on them. I’ve managed with prunes but she always manages to get constipated again. Should I move to a typical formula like Similac advance, will it be harder to digest and lead to more constipation? It’s so tricky. I’m just trial and error right now but i really have no direction. Thank you!!!

    1. Michelle,

      I know it can sometimes seem like stabbing in the dark to get the right formula for your little one! It’s hard to pinpoint because different babies react to different formulas in different ways. Switching to a different brand may help, however. I’ve heard some parents share that their baby would have trouble with constipation on Good Start but be okay on Similac. Another idea is to start adding a little bit of prune juice the the bottle itself. If you decide to do this you need talk with your doctor about how much to add. Hope this helps you get closer to a solution!

  96. My daughter is almost 5 months she is on gerber soothe when she poops she strains like crazy has been for a while her face turns bloodshot red and the poop is dark green and its very little i have done juices foods and everything should i put her on gerber gentle or will that help?

    1. Tosha, I would run this by your doctor – just to make sure. Different babies react to different formulas in different ways. So what constipates for one baby will give another baby diarrhea. There’s no hard-and-fast way of knowing until you do some good ‘ole fashioned trial-and-error. Have you added a little prune juice to the bottle? Definitely give your doctor a call and get his opinion. Keep in mind he may need a stool sample, so keep one of those dark-green poos in a plastic (sealed) bag just in case he asks for it. Hang in there friend, you’re doing great – asking questions is the first step towards a solution!

  97. Also the soy milk has mad his bowels kind of like diarrhea.I feel really bad for him and really just don’t know what to do to help him.i feel like his doctor isn’t giving me much help and I just don’t know what I should do

  98. My 4 week old son won’t stop fussing and has alot of gas even after I burp him and he moves his bowels.He crystal sometimes for 3 hrs and I have tryed to sooth him every way possible. When he was born I was giving him breast milk and the hospital supplied us with 2 days of similac after that wic gave us infant enfamil I stopped breast feeding 2 weeks in because I really wasn’t producing much milk so he was on regular formula.Ever since he was born he been like this even in the hospital he would fuss and cry nonstop on top of that he was having a bowel movement maybe every 2 days but would cry trying to go after every bottle.i took him to his doctor and was told he was fine that babies do this all the time and even after expressing to him that it wasn’t just a fussing cry it was more of a uncomfortable pain cry he told me my son was fine.So last week I decided maybe he needed his milk changed I went and got similac soy and some gripe water.The first night was great we both actually got some rest and he looked so at ease but the next day it was back to his Normal fussing the only difference was he was moving his bowels with every feeding and has so much gas.Its been a week I kept him on this formula and today I went and got enfamil gentlease im just not sure if I should switch him again.

    1. Kimberly,

      It’s not fun when you are trying to find answers and you feel like you are alone in that! First of all, if you feel like you aren’t getting the answers you need from your doctor it may be time to consider switching to another doctor. Secondly, I know that soy works for some babies but I’m not a big fan. If his bowel movements are more like diarrhea then he’s probably not a fan either (or I should say, his body isn’t!). If you haven’t already switched, go ahead and do that. You have read the article so you know what to keep in mind when switching from soy back to dairy. I recommend that you try probiotic drops. This helps with gas in the intestines (gripe water only helps with gas in the tummy). I hope this makes a difference with your little guy! Congratulations, by the way! This is such an intense but precious time!

  99. My daughter suffers from allergies and recently transitioned from Alimentun to EleCare. I have several cases of the 2oz ready-to-feed Alimentum that I’d like to donate to a family in need. It expires in February so please let me know if your or someone you know is interested.

    1. Jeff,
      How very kind of you! I have a thought, if you have a food pantry or a shelter for women in your town I am sure they would be very glad to receive this donation.

  100. Hello my son is now 8 months old and has been extremely gassy since he was about a week and a half old…. We have tried him on every formula down to alimentum formula… I was wondering how long should it take before I see a change… He does good doing the day but is hard to burp but at night he is really gassy

    1. Asia,

      Have you tried probiotic drops? They help with bubbles caught in the intestines and might make a difference in your night time feeding.
      Also, Heather is writing a post about hypoallergenic formulas. It will be coming out this weekend or early next week. I am sure it would be helpful for you and give you and chance to compare what’s out there. If you haven’t already subscribed to the Incredible Infant I recommend you do. That way you will be notified the moment the post is available!
      Hope this helps your little guy!

  101. Ok my 8 mth baby has been on simlac advanced the switch to good start soothe ,tried soy and now simlac dark purple can the alithuim ..hes been on this for about 5 months well he recently started rejecting the milk and pushing his bottle away.well i went back to the soothe good start and he drinks it fine but now he isnt taking his 30 to 1 nap.if he naps its a 10 min nap.and at night time hes really fussy and waking up crying every 30 mins.
    Well idk if im doing wrong but its been 3 days that i started giving him the soothe during the day and the alithum at time night so he can sleep..its been helping but i dont know what else to do..is there any advice or another formula that can help my little one..

    1. Lisa,

      The good news (and the bad news!) is that it can take up to a week to see the difference when you make a change in formula.
      If things aren’t better by now (it’s been a week since your post) try the solutions in Heather’s article for solving formula problems or the suggestions to finding the right formula here. Hope your little one will get some relief!

  102. I came across this post while searching about transitioning between formulas, and oh boy am I thrilled that you are still keeping up with this page over a year later! Lol So my daughter is now 10 weeks old. I breastfed up until she was about 7 weeks old. I had a sample can of both enfamil newborn and gentle ease. I was supplementing once in awhile with the gentle ease while I was breastfeeding because my milk wasnt coming in consistently I guess u could say. she did great with it from what it seemed like. One day my milk was just gone, and I only had the can of enfamil newborn left so I started her on that. That was the WORST week ever for her! Super cranky gassy CONSTANTLY! She also has had acid reflux since she was born, she isn’t on medication because she is gaining weight and growing wonderfully she just is constantly spitting up. When I went to get her more gentle ease to switch her back the stores where I live did not have it. So I got 1 can of pro sobee the soy enfamil and 1 can of the AR because I wasn’tsure which would be best, so iI started her on the soy which she has now been on for over a week. And since I switched her she is constantly hungry and has had hard poops, screaming like I’ve never heard her before, and she will push forever and a little tiny dime size peice will come out after like a half hour of pushing off and on while crying. I’m wanting to switch her to a different formula I don’t think soy works well with her. I’m wondering what you think would be good for her? I can’t get in to see her pediatrian for a couple weeks and I don’t want to make her wait that long when she’s in pain like this. I have the can of enfamil AR still, but I wasn’tsure if the rice in it would make her cconstipation worse or not? Or should I just find a store that sells the gentle ease because I know she did pretty good with that one? Oh and she is not cow milk intolerant or anything! I just got the soy because I thought it would be easy on her tummy. But I was definitely very wrong!!

    1. Jackie,

      I agree with you, ditch the soy! Constipation is such a trial (for the baby AND you). Please take a look at Heather’s article about Acid Reflux here. But I also think it would be wise for you to consider what has already worked for your little one! You might consider ordering the Gentle Ease on line, whatever it takes to help your little one eat and thrive!

  103. I have a 7 week old that was put on soy at birth (for no apparent reason, its what the nurse gave me for her first formula) and now the ped is concerned about the amount of estrogen in soy and told me to switch to gentlease. I had a can of Good Start Soothe on hand so I cold turkey switched her. Since reading your posts I see I did it wrong. Its been 24 hours since she has been on Milk based and seems fine. Should I continue with giving her full milk or should I mix soy/milk to avoid problems? She has always been very fussy and cries all the time. I havent noticed a change in the last 24 hours of her new formula. 🙁 Also, dr put her on milk of magnesia for hard stools. Im wondering if this is the cause of her fussiness, as it kind of started then. Thanks for any advice you have.

    1. If she seems like she’s doing okay, I would continue as you’re going. Sorry for the delay in my response – somehow the computer buried your comment and I’m just now seeing it! As for the constipation, perhaps ask your doctor about adding some prune juice to the bottle instead of the magnesia. Perhaps that can help also with the fussiness!

  104. Me again. I’ll be switching to the baby’s only organic dairy with dha. He took a full bottle of the baby’s only tonight and seems to be doing fine (so far). Do you think we could start off half and half mixture and go up from there or do exactly as you write above? Thanks!

  105. My girl is 3 weeks old. She was very gassy and on Enfamil Infant at the hospital. We picked up Enfamil Newborn not noticing the difference on the label and used it up until yesterday. She was somewhat fussy on the Enfamil Newborn. We tried gripe water and gas drops. She was actually doing really well, but we live out in the country and ran out of formula. We had a big container of the Enfamil gentlease so we had to start using it yesterday. She has been so fussy since we switched. She hadn’t been this bad at all before. So I am thinking we made a big mistake starting this new formula. Guess we should have made the 90 mile round trip to get the formula when we ran out. Any advice on if this will get better? My first child had tummy problems as a baby. He did well on Similac Soy and still drinks Soy only now at age 3. Please help!

    1. Ginger, usually it just a few days. Having grew up in rural Iowa, I can totally relate to the whole “90 minute round trip” thing. Not fun! Have you tried signing up for Subscribe and Save at Amazon? If you’re a prime member it’s free shipping, and you can set it up to mail automatically so you don’t get in this situation again. (I use it for toilet paper, and other “staples” I always seem to forget – it’s a lifesaver!)

  106. my month old has starting to be super gassy and just uncomfortable eating little amounts more often and not in one sitting I took her to the doc to check her out and couldn’t see the doc we had been seeing and he said she might be not ok with the formula we are using Enfamil yellow can and he suggested trying nutragrimen but im wondering if I should try gentle ease I wont get wic for another month or so and cant afford the nutragrimen

    1. Audrey, talk with your doctor about your financial situation. Perhaps he has some free samples or special discount coupons he can offer you for the Nutramigen. He may also be aware of some local formula assistance programs you may be eligible for. Start there, and if you’re not able to get help to afford the Nutramigen, perhaps ask him if you could try Similac Total Comfort instead for a while. That’s a very gentle formula – as gentle as you can get before you get to a hypoallergenic. Perhaps that will do it!

  107. Hi, I love your articles and website! I have a quick question. What if I wanted to switch from a regular formula (gerber good start gentle for supplementing) to an organic formula (baby’s only)? Just switch right over or do it slowly? Thank you!

    1. That’s a great question, Sami! The question you need to ask is this: Are both formulas based on the same kind of milk? If so, than no slow shift is usually necessary. If the answer is NO – say you’re switching from Good Start Gentle to Baby’s Only Organic Soy – than you’d want to follow the directions above. (You’d also need to go slowly if you were going to from a regular formula to a hypoallergenic formula, btw.)

      That’s the textbook answer, of course. The “Mom” answer is to follow your gut. If your baby seems very sensitive and is naturally gassy, you may want to go slow anyway. Just in case. 🙂

  108. My 4 week old has been in Good Start Gentle since birth. About 4 or & days ago he started spitting up and having really bad episodes of having gas. Stretching his legs out and just seeming like he is very uncomfortable. He seems to be uncomfortable during and after feeding. He has a ton of wet burps and gets hiccups all the time. The pediatrician switched him to the Soothe formula. Does this sound like the formula he may need?

    1. I think that’s a great place to start. Soothe is as gentle as you can get without moving to a hypoallergenic. Give it a week and see if it gets any better. 🙂

  109. Hi! I have a cute 8 month old on nutramigen for reflux. She is on solids and doing really well! 🙂 Her dr wants me to transition her to another formula now that she seems to be growing out of it. He would not offer advise as to wich one to try. She is doing so well I am hesitant to just start messing with her little body. During her first 2 months I tried several formulas (similac advance, gentlease, good start gentle) all of which constipated her and did nothing for her silent reflux. It was a terrible time and that I dont want to repeat. I want to follow the dr advise but I’m weary to just start something new. Any advise?

  110. My baby has been on Nutramigen since 1 month old. He is now 4 months and no longer colicky. Can I switch formulas before starting him on solids so his body can adjust to start digesting foods instead of just absorbing the predigested formula? Or do I not fix something that isn’t broke.

    1. I can totally understand why you’d like to try to switch back. Nutramigen is expensive! 🙂 I would firstly run this by your doctor and get his opinion. Then, if you get the thumbs up, I would switch to one of the ultra-sensitive formulas (that aren’t hypoallergenic) like Similac Total Comfort or Good Start Soothe – using the instructions in the article above. Then pay close attention for about 7 days to see what things change. Good luck friend!

  111. My 12 week old has been having tummy issues since day one, mostly bad gas that she had a hard time passing. She was exclusively breast fed so I cut dairy out of my diet and noticed a huge improvement. at 8 weeks I realized her latch had gotten lazy and as a result my production went down and I started to supplement as she is a very hungry and impatient baby! We got Good Start as a sample and she seemed to enjoy it, until the tummy issues started again. I couldn’t get in to see her doctor, so I decided to switch to Gentle Ease (another sample). She did not take to it well and 2 days later we switched to a lactose free formula also from enfamil. She loves it and has no trouble passing gas now but there is definitely more gas! She also hasn’t had a bowel movement in 36 hours, which is not normal for her at all. Would this be because we switched too fast? Or is it normal? I guess I’m looking to have my mind eased a bit until we can see her doctor. She only has 2-3 bottles a day of formula (maybe 8 ounces max. She likes to snack, not gorge)

    1. It’s hard to tell exactly what formula changes do to a specific baby’s digestive system. She may be experiencing more gas due to the abrupt switch, but that should change after a few days. It’s not uncommon for bowel habits to change with a formula change as well. Remember, it’s not frequency that defines constipation. It’s texture. (Nasty!) If she’s absorbing the nutrients in the new formula better, it makes sense she won’t have as much waste. Keep an eye on her next poop, and if it’s thicker than peanut butter and it seems she’s really straining, ask your doctor about the possibility of adding a little prune juice to loosen things up. I hope this can help Sabrina! Sounds like you’re doing a great job!

  112. My LO is 3 months old. She had pneumonia (treated at home with antibiotics) at 7 weeks old. At 8 weeks she had chest congestion and we did a week of breathing treatments. Then 9-10 weeks she would spit up and projectile and out her nose. She was BF in hospital but started Similac Advance our first night home (I tried but was too stressed BF). Ped told us she has reflux so we switched to Similac Spit-up. After one week of it she was so congested she would almost choke. I tried switching to Enfamil Gentlease but that same day she caught a stomach bug and threw up all day. We had an appointment with a reflexologist(holistic/chiropractic doctor) that day about her reflux and was told she did NOT have reflux and her throwing up and congestion was due to her formula. With her being sick that day we had to do Pedialyte for 12 hours then watered down formula for 12 hours then regular strength. When we went to the formula after Pedialyte we used Similac Sensitive. I took her to the Ped the day after reflexologist appointment and they suggested the Sensitive. Well here again it has been another week since formula change and she’s awful congested on the Sensitive, but spitting up is only dribbles. The Ped told me to start breathing treatments. But I had a follow-up with reflexologist and he said try another formula, he suggested Soy. I bought Similac Soy and Ped said it’s okay to switch to it. But I am nervous now. I want to listen to my Ped but I do not want my 3 month old on medicine, she’s already been on too much from 6 weeks on. I want to think the reflexologist is right and it is all caused by formula. What are your thoughts? By the way, I use the Nose Frida and saline daily on her congestion and she sleeps with a cool mist humidifier. She has dry coughs but no other signs of reflux. Never fusses, burps right, stools normal, and isn’t gassy.

    1. Samantha, I’m so sorry to hear about all the stress you’ve been under for the past 3 months! Yikes. That said, you are shining through this story like a beacon of “awesome mothering”. You are asking the right questions, pursuing the right leads, and being the perfect advocate your baby needs you to be. That is amazingly wonderful. Well done. 🙂

      As to your question, I’m really not qualified or educated enough to give advice on this situation. I WOULD however, ask your doctor about whether allergies could be at play here and what their thoughts are on using a low-lactose formula (like Similac Total Comfort) or a hypoallergenic formula (like Alimentium). If it’s a formula issue, it’s usually related to the lactose. (Unfortunately many babies will have a similar reaction to soy than they have to lactose.) Start there and see where it leads. Most importantly, though, know that you are doing all the right things, and in time, these things WILL resolve themselves and improvements WILL be made. Eyes on the horizon my friend! (hugs)

  113. A feeding question…
    My 4 month old son was recently put on Nutramigen due to fussiness, hefty spit up, and lack of weight gain. We were looking to see if there was a possible milk allergy. I was also given a prescription for Zantac to try if symptoms didn’t improve. My baby is seems to much happier after being on the Nutramigen. However, we are still having severe issues with spitting up after the formula switch and Zantac. We also have very liquid dirty diapers. Do you feel as if trying the Enfamil AR for spit up or maybe trying Smiliac’s Alimentum would be our best bet for the next step?

    1. Ginny, I’m sadly not the person to answer that question. I would share this all with your doctor, and see what he thinks. I CAN tell you, however, that if there’s a milk allergy, the AR isn’t going to help you. It’s based on cow’s milk – it’s only prethickened for reflux babies. You could try it for a few weeks and see what happens, but I wouldn’t do so without a doctor’s approval. If he really wants you to stay on the Nutramigen, ask him about adding a little rice cereal thickener to the formula. Also, probiotic drops like these on Amazon have been shown to help with refluxing babies as well – may want to ask his opinion on that while you’re at it. I hope this can help, I’m sorry I couldn’t be more specific!

    2. Thank you for getting back to me. We switched to the AR and with in 24 hours my baby was screaming and tense again. It did help with the spit up. So we are now back on the Nutramigen. However, we are still having the spit up issue. I have added the cereal to the bottles and have not seen much improvement yet. I’m going to give that another day or two to see if I can tell a difference. I can’t decide if we also have reflux with the milk allergy or if my baby just spits up a LOT. Do the probiotic drops help with spit up or just reflux?

    3. Ginny, two steps forward…one step back. So it often seems with these things. Keep persevering and communicating with your doctor on all these changes. I would give it at least a week (if you can) to see how he adjusts to everything. The probiotic drops were mentioned as an effective treatment for acid reflux, but I can’t tell you exactly why (spit up or reflux) because the doctor who was lecturing didn’t get into those details. My guess is both, but a doctor’s answer is ALWAYS better than my guess. 🙂 Hang in there, you ARE making progress, little bit by little bit. You know what’s helpful and what isn’t, which is more than you knew 2 weeks ago!

  114. Hi there, first off- I love your website, thank you! My daughter is now 8weeks old with silent reflux that we thankfully picked up very early but probably due to the severity of her symptoms. Impossible to overlook. Our pediatrician put her on Neocate immediately(to be taken for two weeks and then transition over to Pedicate), it’s now been 8days. Day 1-6 was downhill; remarkably day 7 I had a new smiling happy baby girl. I thought my prayers have been answered. For some reason on day 8 we are right back where we started with the constant screaming; arching back; refusing bottle; hiccups; interrupted sleep etc. Could day 7 just have been a fluke? Could it be the taste of Neocate that’s suddenly putting her off? What’s the next step in terms of formula?(I.e. Do I stick with the Neocate a while longer or do I consider a change, if so to what?) I live in South Africa- the only other AA formula is the Alimentum one but very difficult to find here. I’m not sure why the pediatrician wants to move over to Pedicate(it’s similar to neonate but whey based and less hydrolised)- do I stick it out and follow her advice(what if I do and it ends up not helping) or do I search for a solution for my poor baby girl… Also, pediatrician doesn’t want to medicate, said if this doesn’t work that we would do a gastroscopy/endoscopy on my little one. Heartbreaking. Any suggestions?

    1. Meliska, I’m glad you’re enjoying the blog! I would stick with the Neocate for a few more days and see what happens. I would also seek a second opinion on the no-medication thing. I can see what he’s saying, but it’s hard to tell that to parents who aren’t sleeping and don’t see their baby getting better. Always good to have options. Then you can decide which ones to try and which to ditch. Also, ask him about using probiotics. Recent studies have indicated that can help. Good luck friend, I’m so sorry this has been such a struggle. You’re doing EXACTLY what you should be doing, though, advocating for her. She’s a blessed baby to have such attentive and wonderfully caring parents!

  115. At about 2.5 months the pediatrician put my little guy on Alimentum after he spit up a tiny bit of blood and a little bit was found in one diaper. I stopped nursing and followed his recommendations even though I felt that the blood probably came from me. Don’t get me wrong, I was alarmed. He had been very colicky and was on medication for reflux as well but we had problems with nursing (arching back, biting, pulling). When things didn’t get better, we were referred to a Gastroenterologist who changed his dosage of Omeprazole and added Baclofen and Gerber Soothe drops (probiotic). We saw improvement and were then given the ok to “try” Gerber Soothe formula instead of the drops. I did a very gradual shift… maybe too gradual (2 days 1:3, 3 days 1:1, 2 days 3:1). He’s now been on Soothe alone for nine days. His bowel movements are very difficult for him. Where he was going every 2-3 days during the transition, he’s now going daily but he strains, turns red and often cries. His poos are very solid mixed with looser poo. His eczema seems worse (cheeks and patches on back) and he’s been a bit fussy but he is also teething. I bought Alimentum last night thinking I may need to go back despite the cost ($60/wk) but I guess I want reassurance. Do you think it’s the formula? Have I given it long enough? I am an over analyzer to the tenth degree so… HELP! Please.

    1. Rhyea, what an emotional roller coaster! I think you may be on the right track to go back to the Alimentum (but your doctor will be able to confirm that for sure – definitely share this with him). My guess is that he’s still struggling with the digesting of things. I would talk with your doctor and then go back to the Alimentum for another month and then try again. In particular, make sure your doctor is aware of the straining and having mixed solid/liquid poos. You may also need to bring in a stool sample, FYI. Hang in there Rhyea. It won’t always be like this. One day at a time. (hugs)

    1. Sheri, I believe the supplement formula is relatively new. It’s my guess that the “Supplement” is being recommended for moms who want to do both breast and formula. If you’re not breastfeeding, I would do just the gentle. My guess is that it’s just marketing – that they’re basically the same. But, just in case, I wouldn’t use the “supplement” formula if you’re not breastfeeding. Hope that makes sense…

  116. I find this blog interesting and thought I might share my son’s experience. Since the beginning things were rough. After a failed induction, 2 days of labor, and an emergency c section the breastfeeding thing was nearly impossible. He had jaundice and lost about 2 pounds and despite constant attempts, 3 lactation consultants, and pumping every 2 hours I couldn’t produce enough milk for even 1 feed. Naturally we tried several formulas: similac, enfamil, gentlease, similac sensitive rtf, nutramigen. I was told my son had colic but he didn’t cry often but that was why he had blood in his diaper and projectile vomited, so try zantac. Doctor switch as well as a visit to a gi specialist where the specialist said that’s normal but try elecare. After months of that causing more vomiting the gi specialist said he’d prescribe prilosec but refusing feeds, vomiting then screaming, and occasional blood in the stool was normal and the only thing to do is stay on elecare cause if he’s allergic to anything that won’t aggravate it (never went back to that clown). So the fix which didn’t help was to put rice cereal in the bottle. After a couple more months with zero improvement and a major constipation issue I decided to forget these doctors and switched to holle. Within 24 hours the vomiting stopped. This was the end of February 2014 (he was born august 2013). The constipation was still an issue and I ended up going to a major hospital in Chicago where it was determined my son’s anus was too small. Since that time we have been stretching his butt daily with dilators and he has been on miralax to keep the stool softer. After the holle switch my son was a different baby, and now that we’ve made progress with the dilations he’s been able to go on his own sometimes. We just started weaning him from the daily probing to maybe see if he’ll start going more on his own. The hospital has not ruled out something like hirschsprungs for sure but they seem pretty confident that once he learns to poop he’ll be OK.
    As far as formula the only thing that seemed to be fine was the milk based holle. The thing that seemed to cause the problem was dha/ara. I don’t think it was only a coincidence that my son’s constant spitting up and projectile vomiting stopped within a day of the holle. I thought maybe corn was a problem but now that he eats that and has no side effects the only thing left is the dha/ara. If you’ve tried just about everything and nothing works I’d seriously consider a switch to a formula without it. The only 2 I know of are holle and another called Bellamy ‘ s organic Since it’s easier for me to get the holle I tried that. I know how miserable this all is and I’ve been there, but know that it’s temporary. I know it’s hard to believe when you’re in the thick of it but it will improve and you’ll finally get to meet your real baby (not the crying, in constant pain little being that’s trying so hard just to get a little relief and can’t).

    1. Kirsten, thanks for sharing this with us! I’ve heard Holle brought up a few times, but haven’t researched it yet. Seems like it might be time to dust off my notebook and start digging in! Love your encouragements at the end, that’s definitely something moms need to hear! xo

  117. My baby has been breastfed for 8 months and my supply has decreased so I’m trying formula. I tried enfamil infant it’s only been two days and he has been extremely fussy. Should I try another formula already or wait it out for about a week?

    1. Cassidy, did you by change go slow? Or was it an abrupt switch? If it was abrupt, don’t worry. 🙂 I would try to last a few more days and see if it settles out. If it doesn’t, then move to a gentle formula. You shouldn’t have to slowly switch that time, as long as you aren’t going to soy or hypoallergenic. They’re all cow’s milk. Does that make sense? Hang in there! 🙂

  118. My 8 week old switched to Nutramigen from Gerber soothe after experiencing constipation, episodes of screaming and crying from gas pains during the night, he is also on Zantac for reflux and his pediatric GI suggested that he switched after we tried Miralax and gripe water interventions without positive results. Yesterday was his first day on Nutramigen, he was crying and screaming in the evening, appeared hungry but I didn’t think it was hunger due to his previous feeding schedule. My LO however had a very good night sleep (5 hours straight, and no gas pain episodes like before). I spoke with GI specialist today who stated my LO was indeed experiencing hunger due to Nutramigen not staying in his stomach as long as the other formulas, and suggested for me to add rice cereal to his bottles. Clearly Im not a medical professional but I was under the impression rice cereal in the bottles should be introduced later, before solids? Do you think its best to increase feedings instead? GI specialist said newborns receive this in the NICU and told me to not worry about introducing rice cereal, that it will simply stay in his stomach longer. My LO seems to be doing well on Nutramigen (other than the hunger signs and a few spit ups). He also had two mustardy peanut butter textured bowel movements today, for the first time since he switched from breast milk to formula at when 4 weeks old. I know its still early, but Im excited he showed progress in some areas and would like to give this formula more time. Greatly appreciate the help:)

    1. Marrie, Rice cereal in the bottle is a common suggestion for babies who are struggling with acid reflux. Just follow his directions very closely in regards to how much cereal to put into the bottle. You don’t want it too thick. It’s effective because the cereal makes the milk thicker and heavier, which helps keep the food from sliding back up during a reflux episode. I would follow your doctor’s instructions, but absolutely feed whenever you feel he’s hungry. That may seem like a lot right now, because there’s usually a growth spurt around 8 weeks. Sounds like you’re doing a GREAT job, Marrie! He’s a blessed little boy. 🙂 Please let me know if I can do anything else to help!

    2. Heather this website is God sent! Thank you for the validation and support you bring even when medical professionals (not all) don’t do so. The Nutramigen switch from gerber soothe has worked wonders for his tummy troubles, as he is no longer constipated (has two healthy looking bowel movements a day), and no longer wakes up screaming and crying from gas pain. However, since the switch to Nutramigen, and even with the added rice cereal, his silent reflux is out of control. 45 min to an hour following a feeding he cries, arches his back, makes an agony face, and typically soothes by having a pacifier or his hands in his mouth constantly, he also gets hiccups regularly. Hardly any spit ups however, so I think rice cereal (beechnut) has helped. With gerber soothe we never saw these silent reflux symptoms. My husband and I are thinking of switching him back to soothe following your recommended transition (1 oz of gerber sooth, 3oz of old Nutramigen on first day, 2:2 on the second day, then complete switch), but are hesitant to do so because we then remember all his tummy troubles while he was on it! His GI specialist has him on Zantac and mentioned Prevacid was the next possible medication to add, but was hesitant to do it last week due to possible scary side effects. I considered switching to The AR formula, thinking this might help with silent reflux, but was concerned about possible tummy troubles again as he would have them with gerber soothe. His GI specialist said it is likely that other formulas will also irritate his tummy since gerber is one of the most gentle formulas out there. I’m returning to work in a week and a half, and my heart is in such deep sorrow just thinking about my LO experiencing digestive issues, or reflux from the switch or continuing on the same, and in addition adjusting to sitter:( tough decisions, keep him on Nutramigen with added medication and pray meds will work with silent reflux instead of creating worse side effects, transition to another formula either go back to the gerber soothe (maintain on miralax, gas drops, gripe water, as dr suggested) or an AR formula. I noticed his dr doesn’t seem to not recommend any formula other than Gerber or Nutramigen. I greatly value your knowledge and response, I’m very overwhelmed! Thank you!

    3. I’m so thankful that you’ve found the website helpful!

      A little background on the Zantac/Prevacid thing. Zantac is a medication that doesn’t lessen the amount of acid being produced, it just makes it less acidy. (Hope that makes sense.) Prevacid actually blocks the ducts producing the bile, so it reduces the amount of acid being created. Most doctor’s give Zantac the first try, since babies can be on that for a longer period of time. Prevacid is usually one of the backup plans used because it should only be used for a few weeks, since your baby really does need the acid being produced, it’s just that his valve isn’t completely formed. So it’s used to help buy some more time until he grows a little bigger. You may already know this, but I wanted to share it just in case. Most parents aren’t. 🙂

      I will share some thoughts for you, but please understand they aren’t advice. You and your doctor know your situation best. The best decision will come from both of you. 🙂

      As for the formula, I think your doctor is probably correct about staying on the Nutramigen. New studies have shown the hypoallergenic formulas really tend to well with acid reflux babies. To go back to the Soothe, or try AR (which is regular formula with pre-mixed cereal) may take you in the wrong direction. I would try to wait this out and give the Zantac time to work, potentially using the Prevacid if you have to. You are on the right path, you just have to continue to patient to see how things work out.

      THAT SAID! 🙂 If you haven’t yet, talk with your doctor about adding probiotic drops to your daily routine. (Here’s some baby drops on Amazon.) Recent studies have show probiotics to be very helpful in controlling the symptoms of acid reflux in babies.

      I know this is a extremely difficult time for you. A few things I would encourage you to remember: As far as “good parenting” goes, you guys are rock stars. The hardest thing to do is love and care for a baby who isn’t necessarily fun to love and care for. Anyone can hold a cuddle a baby that coos and smiles the whole time. It’s hard to consistently give love and care to a child who doesn’t seem to want it. (He does, he’s just reacting to the confusion of having pain, which is a new thing for him!)

      As difficult as this time is, take heart in the fact that your little man isn’t going to remember it. YOU will, of course, but there is no long term negative effects to this. There ARE a LOT of positive long-term effects, however, as he learns that his parents are a source of care and comfort for him. He won’t know how he knows this, but he will learn that lesson well, and it will serve him the rest of his life – to know that he is deeply loved, and that you will meet his needs. That’s a big deal. And you’re doing a wonderful job at it.
      This week’s post, I think, will be particularly encouraging to you. I’m just finishing the last edits today. I hope you can find it uplifting. It helped me just to write it!

      You are doing everything you should be doing. You are asking questions, making adjustments, seeking cures. These are all hallmarks of good parents. He’s a blessed little boy. Keep doing exactly what you’re doing, because you’re doing everything exactly right. 🙂

  119. In desperate need of help! At 4 weeks old, I began the transition from BM to formula. I use Enfamil Gentlease. From this time, every evening or middle of the night, my son has a crying session. It typically is after a feeding. It begins about 30 minutes after a 5:30-6pm feeding and he cries on and off anywhere from 1-2.5 hours. If it doesn’t happen in the evening, it will happen at his 1-2am feeding. His cry begins as being fussy to a loud, painful cry that leaves him sweating like crazy. My doctor believes he is just fussy. I am uncertain if this could be a result from the formula. However, if it were, wouldn’t he be fussy after every feeding? Any insight would be great!

    1. There’s no harm in switching to another gentle formula, and seeing if that helps. Give it at least a week and see if you notice any changes. Also, if this problem continues, you could seek a 2nd opinion with a new doctor. It’s not insulting. Science (including medicine) is subject to peer review. So don’t feel guilty or bad if you want another medical “peer” to give him a look over. 🙂

  120. I started brestfeeding my baby until 4wks i did a gradule transition from breat milk to Enfamil Reg. Cows-Milk. At about 6wks she was showing signs of crankiness , constipation , and spitting up. We switched to Enfamil Gentlease, not at a gradual transition as i did with the breast milk. She was still spitting up so we tried feeding more frequently as if she was a newborn (every 2hrs) and sitting her upright for 30mins. This made a difference with the spit up but we started to notice her skin was having a “reaction”. She had signs of eczema, but there were alot of light discoloration all over her chest,tummy,and back. We took her to a allergist wk 1/2 ago. And he couldnt determine what it may be, told us to try out a Soy formula for 3wks and come back. If nothing changes, he will do a milk allergy test.

    WELL… we did a drastic switch and did not transistion smoothy..
    but we went with Enfamil Prosobee and it has only made things worse. She now sleeps through the night 9pm-5:30am . She is taking 3 1/2 – 4oz bottles, but she is spitting up small amts after feeding after a couple burps. Then within hrs until the next feeding she spits up large amts. Its not projectile. but it smells vomity.(< like that word lol ) .. Her poop has changed to harder stools also, one in which had little bit of blood. She doesnt show signs of discomfort from spitting up. She will get cranky when you pull the bottle away to try and give her a break. She has always showed great signs of weight gain.

    Her skin is showing a very little change.. So ive read and read and read but im still timid and dont know what to do. Do i try a DIFFERENT BRAND soy formula, go with a more sensitive formula like Gerber Good Start, or a well mixed broken down formula like Enfamil Pregestimil ??? Like i said the Allergist could not pin point if she had a milk allergy but bc she is so young he wanted us to do some trail & eroor before performing a milk allergy test ( URRGH)
    HELP 🙂

    1. Michelle, what a nightmare! I would talk with your doctor about potentially trying out a hypoallergenic formula like Nutramigen or Alimentium. It’s very common for babies with a milk allergy to also struggle with soy. (Not guaranteed, but common – he was probably hoping your daughter would do better on the soy, thus saving you a lot of money on the hypoallergenics.) Talk to him about that option and see what he says. Since you’ve tried the gentle formulas and now the soy formulas, it seems the hypoallergenics is the next logical step, but he would know best.

  121. Made a HUGE FTM mistake. We just recently (like 24 hours ago) switched to Alimentum by docs suggestion. The Dr didn’t say anything about transitioning and I had no idea and gave her Alimentum from goats milk. She is now constantly crying with, what I assume to be, tummy ache. Which I now completely understand given the abrupt switch. Should I go back and start transitioning or keep on since the damage is done?

    1. If you’re not switching due to a severe reaction, I would go back and move slower. That said, it took me a few days to approve your post (the weekend) and I’m just seeing this…so you could just push through it and hope for the best. Don’t worry Heather, though. It’s a mistake we’ve ALL made at some point! Some babies don’t seem to notice, so it can slip by, but it sounds like your little girl seems like she noticed. Hope it’s better now!

  122. We started today with switching OFF of Alimentum to a lactose free formula. Baby is 5 months old and I’ve had suspicion that her issues when she was one month old that led us to Alimentum Were just general underdevelopment age-related issues that she has since grown out of. We were able to trek her off Zantac a little over a month ago with no problems and I don’t think she actually has MSPI. I think the Alimentum helped for a time because of her silent reflux. Anyway for the sake of our pocketbook and that awful dog food smell… We are trying lactose free. Doc said to do first morning bottle all lactose free and then Alimentum the rest of the day. Do that for a few days then up it to two full bottles of lactose free and so on. My question is: If she truly had a milk protein issue wouldn’t that first bottle today upset her tummy by this afternoon? And if it hasn’t couldn’t we move forward with your method of combining some of each in each bottle? TIA!!!

    1. I would follow your doctor’s advice first. He’s spent the big bucks on learning all the ins and outs to give you the most accurate information for your specific child. Did they do a test to confirm the milk protein issue? If not, you could ask him about that.

  123. My daughter is 8 weeks old (but born 3 weeks early) and is on Zantac for reflux. At about 3 weeks we changed her formula from enfamil newborn to similac sensitive, because she began being very fussy and gassy, and that is what my son took when he was a baby. We didn’t notice a difference and she was getting constipated, so after a week we tried Good Start Soothe since I’d heard so many good things. It seemed like she very quickly was a happier baby and didn’t have gas pains and grunting as much, but then after a couple days started crying a lot (much more than her normal) and this is when we went to the doctor and got the reflux diagnosis. I switched her back to enfamil regular because the gas was better to deal with than the crying. To me it seemed like the Soothe made her reflux worse, although it helped the gas and everything else. Dr didn’t want to add rice cereal to her bottles. Btw, her symptoms were of silent reflux, refusing bottle, fussy while eating, waking, only taking small amounts. So after about 10 days on the Zantac I wanted to try the Soothe again, hoping that since the reflux was controlled she could tolerate it. But we are back in the same boat, and she is crying much more than normal with the soothe and it doesn’t seem to be helping at all. Should I just go back to Enfamil where her reflux issues seemed to be controlled but had the horrible gas? Will all of the sensitive formulas basically be the same if I’m not able to add any rice cereal? I’d like to have the best of both worlds for her and be able to help her gas and reflux but isn’t happening so far. (Btw we use gas drops and do everything else for gas/reflux as far as during feeding etc). Our Ped isn’t big on changing formulas and doesn’t really recommend so I’m just trying what I think will help. Thanks! Love this site!

    1. Being the parent of a reflux baby is ten times more difficult because you want so much to fix things! It’s hard to see our little ones suffer!

      I would go back (or call) your doctor and ask him about a few things.

        There are pre-thickened acid reflux formulas out there, they tend to clump less in the bottle and you don’t have to guess with the rice cereal, since it’s premixed. Here’s an article about them.
        Some studies have shown that babies with reflux also have allergies that can exacerbate the reflux. They show that sometimes using a hypoallergenic formula can also help with the symptoms.
        Finally, recent studies have shown that using probiotics is also helpful. Here’s an example of infant probiotics on Amazon – I would ask him about those as well.

      I hope this can give you some new things to try, Aubrey! Hang in there friend, and keep seeking solutions. Your daughter is a blessed little girl to have some loving parents!

  124. My 5 week old just started Alimentum but I found out WIC will only cover Nutramigen. Am I safe to switch straight over since they are basically mob brothers?

    1. Run it by your doctor to be sure, but the prevailing thought is that yes, since they’re mob brothers 🙂 there should be minimal tummy trouble.

  125. Hi heather. I have 7 week old twins. They started on similac advance but had problems with gas so we switched to similac sensitive in the orange can. My girl is now doing fine but my boy was constantly throwing up. He has been to the er and pyloric stenosis was ruled out so the dr thinks it is reflux. He is still gaining weight just not as much as his sister. We tried adding rice cereal to sim sensitive and it was terrible. A few days ago we switched him to soy and he is doing much better. I read so many controversial things about soy and would rather he be on a milk based formula. Do you have any suggestions for a milk based formula or do you think he has a milk allergy? Thanks so much for your help. It seems there is no one to talk to about all of these feeding issues and my dr doesn’t seem to be worried that he throws up at every other feeding

  126. Thanks for the advice. We switched to hypoallergenic formula-Similac- last night since the soy had him so constipated. Today he is ok but he is still trying so hard to pass a BM. Last night he did have bm with help…it was rock hard and green. Hoping he regulates soon. I gave a little water to help. What all have you heard about the hypoallergenic formulas? Are most problems solved with this? I know it is “liquid gold” but I’m willing to pay if it helps him out. When he reaches a year do most babies have issues with milk or are they okay?

    1. Becki, it really depends on the baby – how the hypoallergenics do. It sounds like you are doing the right thing, though, for the time being. Hopefully this will really help! Whether he has issues with milk at a year will depend on a lot of factors, including family history. Your pediatrician is best to answer that one. One other thing I thought I would mention: I’ve been hearing that some doctors have suggested adding some Miralax to bottles to help with constipation. I would NOT do this without a doctor’s advice, since it will be very important to get the right dose. However, that is something you could ask your doctor about if he is still having problems with constipation later this week. Hope things really improve!

  127. My son was put on similac sensetive for some feeding issues in the NICU and he was always very grunty and seemed uncomfortable so when he was 2 weeks I switched him to soy bc that is what my daughter was on when she was an infant. He seemed to do ok although the grunting did not improve and he was now having a little more difficulty pooping so doc said 1/4 to a 1/2 a cap of miralax in his bottle bc we were having no luck with Karo syrup. I found this article after I switched yesterday afternoon and I switched him back to sensetive (he is 6 weeks now). At first he seemed to do well was passing gas easier but today he was fussier and acting more hungry than normal and tonight he was screaming. After reading thus I’m sure I shocked his system. Where do I go from here? Should I just stay with it for a week, should I add half soy back in or is it silly to do that since it’s already been 1 1/2 days? I feel wakeful and like I screwed him all up? Any advice would be helpful!

    1. It’s okay Kelly, these things happen. (I NEVER figured this out with my 2nd, and we switched several times – poor thing!) Since it’s been a few days, I would just proceed and give it a week. Make sure your pediatrician is aware of the change you’ve made and you keep him up on the symptoms and things you’re experiencing. His advice is 10 times better than mine! 🙂

  128. Hi my baby use Similac d blue tin but he was constipated so i went on 2 d orange tin same Similac for fussiness& gas he is 2months now an I realise he drinkin d tea sometimes he u to drink 4 ounce he drop to 2ounce or 1 or none pls what should I do?

    1. Firstly, I would start weighing him every day to start watching for possible weight loss. If this continues for the rest of the week, give your doctor a call and ask for his professional opinion on the weight and feeding changes.

  129. Hoping someone can help. My son is 5 weeks old. The first week I breastfed. Then we slowly moved into Similac Sensitive. We were on that for about 2 weeks but awful gas and back arching. Dr. suggested moving to the Total comfort. So we moved to that and he did well but his BMS turned black/green tar like. I called the dr after about a week of this and he said we needed to make the switch to soy. He was concerned for blood in stool. We switched to Prosobee last night and since then he has been so fussy and hard to comfort. It has only been 5 feedings so I know I should give it time. Just hard to watch. The doctor said the next step would be to try hypoallergenic formula. What is your take? Do you think if they have issues with milk-based he will continue to have issues with soy or is it normal to see crying when switching? Also, which hypoallergenic formula do you prefer?

    1. I’m not qualified to disagree with a doctor – always take his opinion over mine. It is very common for babies who struggle with milk to struggle with soy. My guess is that your doctor wanted to try the soy first, since it’s so much less expensive. If you had to switch abruptly, the fussy gas may be attributed to that as well. Share these recent developments with your doctor and see if he thinks it’s time to go over to the hypoallergenic right now, or to wait a week. I don’t really have a favorite hypoallergenic, since different babies do differently on different brands. 🙂 Start with whatever your doctor recommends first, and then test and try. I know this is exhausting, but every change and adjustment is really a step in the right direction towards finding the formula that works best with your little man. Hang in there!

  130. Hi Heather! Thank God for your blog and you for taking the time to answer. Here’s my story: my daughter is 6 weeks old.she’s been getting about 10 oz of breast milk a day and the rest on similac advantage since she was born. She’s been having very loose stools since birth but the ped doctor said it’s normal. However in the last week she went from 4-5 bm a day to once a day ( maybe twice if we are lucky) very loose green smelly bm. She’s gasy, fussy, and uncomfortable most day but closer when she has to go but there’s no spitting thank God. She had been showing colic symptoms since she was 3 weeks so I’ve been using fennel tea and gas drops as needed and that seemed to help. My question at this point is should I switch her to perhaps similac sensitive or continue with advantage? She’s putting weight on as she’s getting heavier as she grows, have not weighted her yet, but what bothers me is the very loose stools since she was born. They have never been pasty or harder than few curds here and there in the beginning. I hope I’m not making too much of this than it is, as in trying to ween of the breastfeeding as I return to work in 2 weeks. Thank you in advance.

    1. Alina, thanks so much for commenting and sharing your dilemma!

      If she seems uncomfortable to you, go ahead and try the Sensitive formula for a week and see if she improves. If not, Similac does make a “Next Step” for sensitive-tummies babies called “Similac Total Comfort” that is the next rung on the gassy-tummy ladder for Similac. Sensitive has less lactose and Total Comfort has less lactose AND partially broken down proteins. So usually they recommend starting with the Sensitive and then trying the Total Comfort as a backup before a hypoallergenic formula. (Does that make sense?)

      Also, have you talked with your pediatrician about giving your baby probiotic drops like these? That could also be helpful. However, don’t give her anything without talking with the doctor first. He’s the baby health guru here, not me. 🙂

      I hope this can help! Please feel free to comment back.

  131. Hello
    I BF but wanted to introduce formula as I’m returning to work and am going to supplement with formula. Also, I got the flu a couple weeks ago and my supply went down so low I could barely produce enough. I have tried four different formulas and none agree with my little one. He is 13 weeks. Each time intry formula, if it doesnt work out then i take him off the formula and waite a week to introduxe a new one. Each time I’ve tried formula, I do 3.5 oz BM and 1 oz formula in three of his daytime feedings. I’ve tried gentle ease and it made his cheeks really red. Then I tried enfamil and he got red splotches all over his body. I tried earths best sensitive and he was crying in the evening and wouldn’t settle and woukdnt sleep all night. I tried Gerber good start and slept good at night but wouldn’t settle and nap during the day. Now I’m trying similac sensitive and he won’t sleep at night and wakes every 15 min. I had an allergist test him and he is not allergic to soy or milk or wheat. I don’t know what to do. Each time ive troed a formula, i only try it for about two days and pull him off if it isnt going well. Any advice? Also, should I try the formula for longer; will he get used to it?
    Thank you. This is so stressful, I appreciate the advice.

    1. Erica, I can totally understand your frustration! I think your instincts (to try the formula for a longer period of time) are spot on. Doctor’s usually recommend a week. This is because it can take a week to get the OLD formula completely out of his system and see exactly how THIS formula is affecting him. Otherwise you don’t really know if it’s the current formula that’s causing the trouble, or the one he was on three days ago. Does that make sense? Try the Similac Sensitive for a week and see if any of these symptoms start evening out. I would also talk with your doctor about whether using probiotic drops could help his little digestive system. Here’s what they look like on Amazon. They’ve been shown to be helpful – but since he’s so little I would definitely talk it over with your doctor before trying.

    2. Heather

      Thanks so much for the help. Each time I try a formula, If it doesnt agree with him then i pull him off the formula and exclusively BF for a week before introducing another kind of formula. so I know each time the other formula is out of his system. This way I know for sure it’s the new formula if I have trouble. I’ve done this every time ive tried a formula. Also, he has been on Gerber Soothe drops for seven weeks and they have a probiotic.
      My question is, if he’s been off formula for a week and has Been exclusively BF and I introduce a formula and it upsets him and hes up all night, then do I stick with that formula for a week and see if he gets used to it? Or do you pull him off and continue to BF for a week and then try a new formula a week later?
      I’ve now tried five formulas and none have worked. It’s so exhausting and confusing and frustrating. :((

  132. Hi. I hope you can help. My daughter is 4 1/2 months old and around a month old we were having a horrible time finding a formula her system could tolerate. Eventually, after having no luck with most everything we tried, including Alimentium we put her on Similac Soy and suddenly it was as if we had a different baby. No more non-stop crying. She would sleep for longer than 20-30 minutes. No more diarrhea and constant farting. Within 3 days she was a happy baby. Since then, we have had to dEal with thick dark greenish/black poop, but otherwise no other issues.

    We tried getting formula through WIC but they only will offer us Enfamil Soy (which caused constipation so bad that juice/water didn’t help and our little girl would scream while pooping and would actually cause bleeding). Even with a Dr’s prescription WIC was unable to offer us Similac (which she tolerates). So, we struggle to buy her formula ourselves.

    Recently, I made a friend who offered to share her breast milk with our daughter. She does eat dairy, but since we were never told our daughter had a milk allergy, I was willing to try it.

    The first day I offered her one full feeding of breast milk. No reactions.

    The second day I gave her 2-3 bottles of breast milk and noticed she was spitting up a lot that night and didn’t sleep as well as usual, even though at night I was feeding her the soy. Her poops we more thinner in consistency and easier for her to pass though not watery.

    I took a day off from breast milk to see if she improved. It was a typical day and night.

    Yesterday I gave her a bottle of breast milk with no apparent reaction. However, today my daughter pooped and it was a more normal pastey soy poop (thick but not a solid). What freaked me out was, she screamed as if in agony as she continued to pass this soft thick paste. She often passes more solid type poops and it doesn’t phase her, she just grunts.

    I can’t be sure but I think I saw a small streak of blood on one part of the stool. However, when I tried to dab it to see if it was truly red the stool was so sticky it smeared to the wipe I dabbed to it, so I can’t be sure.

    I have a feeling she is allergic to dairy and she is reacting to the dairy in my friend’s diet but how do you really know?? I hate using my daughter as a guinea pig and after going through so much trial and error previously.. I am about to stop feeding her breast milk now.

    And if it is a dairy allergy.. Can babies grow out of it? Poor baby.

    1. Kat, poor baby indeed! You have all been run through it!

      Unfortunately, I can’t give you advice about this. I don’t have the medical training that could give you a solid answer. I CAN however encourage you to go back and share this with your doctor (along with a dirty diaper so they can test it for blood). He has years and YEARS of training to answer these questions, and it’s just way out of my league.

      I will tell you, however, that you’re being a GREAT mom. You are seeking solutions to your questions. Sometimes we have to ask and look for answers longer than we would like with our kids, but you’re still asking those questions and seeking answers. That’s the hard work your baby needs you to do, since she can’t do it. And you are doing it beautifully. Keep at it Kat! You are the best mom for this precious little girl, and by asking these questions until you find answers, you are being her voice. Well done. Keep at it, friend!

  133. Hey Heather! I was going to ask your advice on a formula issue. We had out sweet girl six weeks early at only 3 lbs 13 oz. She is doing well and growing everyday but we can’t seem to find the right formula for her. She was in the NICU for a week and was eating Enfamil Enfacare 22 Calorie and breast milk. I fed her that and breast milk for six weeks and just couldn’t produce anymore. At that point, I had her strictly on the Enfacare. She started to get constipated, excessively gassy and fussy, dry skin all on her face and forehead. Nothing my husband and I did could comfort her or give her relief. She started arching her back, bending her legs, spitting up, etc. so we thought it was reflux and some tummy issues. The doctor switched us to Nutramigen and gave her a prescription for Zantac. For a few weeks she seemed to be okay but her bowel movements have gotten worse and worse. She has diarrhea all the time and it’s a constant battle with diaper rash. A friend of mine had a lot of luck with Gerber Good Start so I thought we would try the Protect in the green can because we have heard wonderful things about it. We’ve been mixing half and half her our Doctor but she still seems so fussy but doesn’t seem to have diarrhea. Should I just switch to the Protect cold turkey and see how she does? Any suggestions? I just don’t want her to get constipated again! My cousin also said Soy could be an option? Any advice would be greatly appreciated!!

    1. Crystal, poor little baby girl! So sorry to hear it’s been a bit of a roller coaster! Whatever you decide, since she was premature and had some health issues I would run it by the doctor to make sure. If she’s on Nutramigen now, I would potentially consider going to Good Start Soothe, it’s the gentlest of non-hypoallergenic formulas, and is a good way to step down. I would also NOT do cold turkey, but follow the instructions in the article above, since you’ll be moving from the Hypoallergenic family to the Non-hypoallergenic family. Again, get your doctor’s input and blessing first though! He’s got a wealth of knowledge and can give you the best advice. 🙂

  134. My son is 8 months old. My son is constantly up through the day screaming with gas. At night, he gets up every 1/2 an hour to 2 hours sometimes if we are lucky if we get 3-4 hours and that has happened a handful of times. Went to see the dr and was told to try acid reflux medication. We tried this for 4 months and did not get better. Finally switched formula Gentle ease, just as bad then went to Lactose free. He is still just as bad. He does not tolerate any cereal or solids (fruits,veggies etc..) wondering if should change to soy formula. Desperate sooooooooo exhausted!!!!

    1. Oh friend! That’s so difficult! What a Gold-Star Mom you are! I know this is hard, but you are slogging through day after day, and that deserves some praise. Well done. My suggestion is to see another doctor and ask him about getting him tested for allergies. Something is definitely going on here, and the first doctor doesn’t sound like he was too helpful. Dig for answers, you are your little man’s advocate, and if your mommy-gut is telling you something’s wrong, you have every right to pursue answers. Ask your friends or on Facebook for some good pediatrician recommendations in your area and then set up an appointment to see him this week, if at all possible. I wish I could give you more answers, but I don’t have the medical training, and I think a physical face-to-face talk with someone qualified to help you is going to be your best bet. Hang in there!

    2. Sounds exactly what we went through but after a 1-2 months we switched to soy and saw immediate improvement. I’m not saying you shouldn’t do what Heather said and go see about allergy testing.. I just can’t imagine going through that for 8 months. Trust your gut. Obviously your little one is not tolerating the formula well. Hang in there!! *hug*

  135. Hi Heather!
    I love your site!! So informative, thanks. My Joey is 21 weeks but born 5 weeks premature so adjusted age is 16 weeks. Initially solely breast fed while in the NICU. At 7 weeks he became very gassy. I tried doing everything I could to help. Long story short, even after seeing a GI specialist we are still dealing with his gassiness and crying, especially at night. So unbelievably frustrating and sad. No sleep = unhappy family. Well not all the time. He has went from breast feeding to nutramigen, then neocate, then enfimil prosebee back to nutramigen. We have some relief but then he resorts back to being miserable and always has gas.(burping-even 3 hours after a bottle and farting-both keep him from sleeping sound, therefore overtired. I’ve tried it all. Colic calm does help but isn’t solving the problem. He’s on Zantac. Just today I decided to switch to gentle ease. He’s had 2 bottles. I’m giving him 2 oz GE to 4 oz nutramigen which is what he’s been on for 5 days. Do you think this is a good choice to switch to?? Any suggestions or help I’d greatly appreciate. Again, love your site!!
    FYI so far today he’s napped 2 times at 1 1/2 hours each which is more than he has in 2 days. The soy to nutramigen really messed him up. Was pooping 3-4 times a day, very soft stools and now has a raw heinie. My poor boy… Please help!

    1. Danielle, what a nightmare! He is so lucky to have such loving and attentive parents! As you’re switching, just make sure you’re giving each formula at least a week to work through his system before trying another one. Has he been checked for signs of acid reflux or tongue tie? A recent reader had similar issues and they discovered that a tongue tie was causing her to swallow lots and lots of gas. Another thing to discuss with your GI specialist is perhaps trying, for a short term, Prevacid or Prilosec. Zantac makes the spit up less acidic, Prevacid and Prilosec actually cut back on the spit up. Those are just some things I would ask your doctor about. If you feel that this doctor isn’t helping you find solutions for your baby, I would definitely seek a 2nd opinion. I hope this can help Danielle! Hang in there, keep seeking answers!

  136. Hi Heather,
    Your site has so much great info, thanks! Quick question : Are Alimentum and Gerber Good Start Sooth considered to be in the same “family”?

    1. No, Alimentum is a hypoallergenic formula, and Soothe is considered a almost-not-quite hypoallergenic. I would consider them as different and move slowly, just to limit the possibility of extra gas. Hope that helps!

  137. I am so glad to come across this post! My 6 week old was just diagnosed with reflux. When he was born we had a hard time latching him on the breast so the doctor had us supplementing with gentle ease…this gave him terrible gas and he started gaining weight (went to exclussive pumping) so he took him off.
    My supply has gone down and with the reflux my doctor suggested supplementing with AR formula. Well, it’s been 3 days and I’m thinking he’s got an allergy to it. I read the other article and he has the ring on his bottom that won’t go away and little bumps on his chest.
    My question now is which direction to turn!?! I just have no idea honestly and need some help!

    1. Miranda, I would give your doctor a call and let him know. Usually the recommendation is to give every new formula at least a week to get into the system, but if there’s an allergy he may recommend doing something different. It’s a good idea to let him know what’s going on, and then he can let you know whether to switch or not.

  138. Hi Heather,

    My doctor suggested that we take my 6 month old son off of Similac Neosure. He was a month premature and had been on the Neosure and breastmilk for 4 months. He had been on strictly on Neosure formula for the past 6 weeks. Two weeks ago we switched him to Similac Advanced and he had a bad reaction. He was pooping a lot, it wasn’t diarrhea, but it cause a severe diaper rash. I took him off the Similac Advanced and put him on Goodstart Gentle for the past 8 days. He is still pooping all the time, it isn’t diarrhea but a yellow soft consistency. He is pooping about 6-11 times a day. Should I wait a little longer to see if he will adjust and stop pooping so often. Or should I try to switch him to another formula, Enfamil? I wanted to start him on solids soon, but I wanted to wait until this formula situation is a little more settled. Thanks in advance.

    1. Priscilla, always wait at least a week between formula changes. And I would also get your doctor’s input on the 6-11 times a day pooping, just to confirm there’s nothing else going on there. 🙂

  139. Hi Heather,

    I wrote to you a while back about switching my baby’s formula from good start to similac and you were right. She immediately stopped vomiting. Thank you so much! I just wish Wic would give me the similac sensitive but they don’t I guess I’m just going to bite the bullet and keep buying it =( do you know their laws on it in Florida? It’s getting very expensive and I’m not working so it’s really tough sometimes. Also she’s 4 months and refuses any kinds of solids I’ve tried everything. Maybe she’s not ready yet? Sorry for all the questions !! Your advice is very much appreciated.

    1. Cindy, I’m so glad to hear that things have improved! I’m afraid I don’t know the laws in Florida much. My social work experience was limited primarily to Indiana and Tennessee. However, I did some brief searching and found this WIC document you may find helpful. It appears that if you can get a doctor’s approval that you need the Similac instead, WIC may provide that for you. Obviously, you seem to have a good case for needing the other formula. I may be completely wrong about this guess, but I would encourage you to call your doctor, show this form, and ask if it means what we think it means, and if SO, if he would request an exemption to purchase the Similac instead. Praying this works out for you, please let me know what happens! (hugs)

  140. Dear heather:
    My baby is now 7 months old, he was completely on breastfeeding till 6 months and then I gradually introduced formula (1:3, 2:2 and 3:1) within 5 days, on the sixth he started vomiting immediately after feed. I have changed the milk but no better, vomiting even if just very little amount of the milk I added. he is fine with pure rice so I mixed it with little amount of the milk, the result was immediately vomit. I have mixed rice with baby food containing some milk, vomiting for 2 days and then be fine but not happy. naturally, I asked the doctor, said give him the milk gradually but I do not think it is the right way as I have been 5 weeks trying. I really need your advice. Thanks in advance

    1. Nagat, firstly make sure you are keeping your little one as hydrated as possible. Give him clean water if you have to, you want to do what you can to prevent dehydration. I once put ice chips inside a dishcloth, and used a rubber band to seal off the end (so it’s like a cloth-popsicle) so my little one could gnaw on it and drink in some fluids. It sounds like he’s vomiting, no matter what you give him? Is that right? On solids or on formula? I would encourage you to visit the doctor and have him looked over. If your current doctor is less-than-helpful, see if you can get a second opinion. In this situation, I think there may be something else going on other than a formula intolerance. Just to make sure, I’d have another doctor look him over. Poor baby!

    2. Thanks a lot for your quick response, do not worry about hydrating as he is fine with breast feeding, water and juice but not any amount of formula milk (I have tried two different types and the one in baby food). Also I have asked two doctors, both said he is not allergic to cow’s milk (with out test) as they both said the vomiting is not sign off allergy????, and his stomach does not like the formula, introduce it gradually but I don’t think that!!!!
      wondering if you have any advice

    3. Okay, so he’s only vomiting on the formula, and not because of an illness. (Sorry, I didn’t understand that!) In that case, I would consider trying a different brand of formula, like Good Start Soothe (seen here on Amazon). Give it a week and see if he fares any better. Good luck!

  141. Thank you thank you thank you thank you.
    When I came across this blog post about a month ago I had no idea that it would change my life. My once fussy, irritated, grumpy baby has transformed into a happy baby! All because of a formula change. I cannot thank you enough.

    1. I’m so glad to hear that Kayla! Thanks for taking the time to write back with your good news! Totally celebrating with you! *highfive* 🙂

  142. First, I wish I had known of your blog with my second son. He suffered from major constipation and his pediatrician was never much help!

    My 3rd son is 5.5 months old and has been on Good Start Gentle pretty much from the start. He went through a brief period of excessive gas early on, but no trouble since. He spits up a lot, in between feedings mostly. But the biggest issue is that all of his poops are very loose. I’m starting to wonder if we need to try another formula? He poops a few times every day. All are very loose, and most cause blow outs. This has been going on for over a month. He sees his pediatrician in a couple of weeks but was wondering if you had any advice. Thanks!

    1. Melinda, I’m so glad you’ve found me! I’m not qualified to give guesses as to what could be causing the loose stools, but if it doesn’t have any mucous in it, I’d say go with your instincts and try a different formula like Good Start Gentle or something. Just make sure you give that new formula at LEAST a week to see what happens. Skipping around to fast can add problems, rather than fix them. 🙂

      BTW, if you do see mucous I would give your doctor a call, it could be a virus and he’ll want to know 🙂 Good luck!

  143. Hi! Is it okay to mix Similac LF with Babynat Organic milk? Our 6 weeks++ son have been drinking Babynat Organic cows milk for around 4-5 weeks, he got some greenish watery poo but not frequent like diarrhea case, that’s why we think it might due to the organic cows milk. What is your opinion on organic cows milk and is it okay for us to mix the milk?

    1. James, I’m afraid your question is over my expertise level. It’s very important babies get the formula, since they need the extra nutrients that you don’t find in just plain milk. It’s my (unprofessional) understanding that it’s best to wait until 5-6 months to introduce regular dairy to a baby’s system, in that they don’t have enough of the good bacteria in their gut to process it. My suggestion would be to A) contact a pediatrician on this issue and then B) conduct a little experiment. Give your son a week’s worth of bottles without the milk added (so either using ready-to-feed or powdered mixed with water – but not nursery water) and see if you see any changes. Hope this can help!

  144. Hehe! You’re FIL is a rather smart man, we love it here and are born and raised kiwis! The skiing is fantastic, and soo are the summers 😀

    Thank you for your response, it made my day. Last night he actually slept almost right through (which is what he normally does) he guzzled a whole 200mls extra and went straight to sleep. Im thinking his tummy is settling on it. We had gone away to the beach on holiday last week when I was starting him on it, so im guessing he just wasnt settled to begin with.
    Its been a big wake up call trying to figure out what he can and cant eat at the moment.

    If he hasnt settled by the end of the week, ill have a look at the others you have suggested.

    Once again thank you soo very much 😀

    1. Jess, always happy to read when a mom feels the confidence that comes with realizing that your instincts are actually spot-on! 🙂 I hope you don’t have to use my suggestions and things continue to get better! As or the kiwis…pretty sure my girls would pass out from all the cuteness! 🙂 (Totally adding that to my “When in Heaven” list!)

  145. Hi there, I’m from NZ so have different formulas to you guys but my qurstion is about my 11 month old little man.
    He had a bug not so long ago that gave him diahrrea. However, this continued for a good two weeks following (was happy chappy still though) I starting doing a little research and found something on late developing lactose intolerances. So I watched him after he would have a normal cows milk based bottle. (Stopped breast at 9months) The diahrrea seemed to co-inside with his milk bottle almost an hour later each time. So I brought a soy based formula and tried to that this week. (Without knowing youre supposed to I troduce it slowly) For the past 3 nights hes woken up crying in pain and only wants to be cuddled. (Absolutely draining me) Then this morning he would only lye comfortably over my tummy with me rubbing his lower back. He then did a good morning poop, which had gone back to a normal consistancy since being on soy.
    I am wondering if you think its because I didnt introduce it properly that hes in pain or the fact he may have an intolerancy to soy aswell? Will probably end up taking him to dr soon either way, but wanted your opinion first. (He is still eating and drinking and being my normal happy boy)
    Thanks in advance

    1. Jess, firstly…I’m only a TAD jealous you’re writing me from NZ. (complete lie, I’m totally jealous!) My FIL lived there for a year, working as an ER doctor and he just loved the people, the scenery (and most importantly to him…) the skiing. 🙂

      Okay, the more important things: It’s not uncommon for babies with lactose issues to not do well on soy. (Not exactly sure on the science behind that, but it’s true.) I would look around for a hypoallergenic formula based on amino acids. If he’s got a lactose issue, he should do okay on those. I know you don’t have the same formulas, but just to give you an idea of what I’m talking about, here are these hypoallergenic formulas…pay particular attention to PureAmino, Neocate, Elecare, any formula that has “Amino acids” as it’s base. Those should help!

  146. Hello my 7 month old baby girl is on nutramigen lipil 1 the docter put her on it when she was a month old he said she was milk and lactose intolorence but he did not test her for it. The doctors have told me to get cow and gate and put one scoop in her bottle with the other milk. Shes started with really bad tummy ache like she did when she was born. How long will she have to do this for till she can get a test? Today we put 2 scoops in and we have to add more everyday but she gets in bad pain at night time. How do i get them to test her and when?

    1. I’m not sure how they do tests for that in the UK, Fiona, so I can’t help you with that question…but I would encourage you to seek a second opinion if you possibly can. If it’s been a few days and she seems worse, call you doctor and see if you can try a different hypoallergenic or gentle formula.

  147. Hi Heather,

    My daughter is 5 weeks old and was 3 weeks early. She was strictly breastfed for the first 2 weeks but then was not gaining weight so my doctor had me supplement and gave me a can of Enfamil Infant. My mom thought she was too gassy on the formula so we switched to Enfamil Gentlease and my milk supply was diminishing so she eventually moved to all formula for about a week, but she had diarrhea every diaper. I figured this was a reaction to the lactose so I switched her to Similac Sensitive for the past two weeks. At first she did really well (stools were good) but now she has been really constipated for the past 3 days. I’m debating between going back to the Gentlease and giving her more time to adjust to it or going to soy… I was on soy as a baby, so my mother suggests I try it with her, but I’m not sure what is best. What is your suggestion?

    1. Michelle, this is a total side note, but wanted to mention it in case no one has gone over this with you: Always remember, as you’re looking at her milestones and watching her gain weight and grow, that she’s not really 5 weeks old. Her brain is saying she’s only 2 weeks. So all her development has to be recalculated to compare with a 2-week old, and not a 5 week old. Just wanted to mention that, since some preemie parents can start to get concerned that their child is behind, when really their baby is spot on, you just have to adjust the age. (Does that make sense?)

      As to the formula, if you don’t want to switch formulas, give your doctor a quick ring and ask about adding a half a teaspoon or a teaspoon of prune juice to her bottles. (Ask your doctor first, though, preemies require extra checking!). That usually helps to soften things up.

      Or, if you don’t want to do that I would try Good Start Gentle. I’ve found Good Start brands to usually be the most gentle and anti-gas for normal-baby-tummies. (That’s completely my opinion. It’s not a paid endorsement or anything…)

      As for soy, I have nothing against using soy, it’s a great formula base for some babies. It has been linked to some controversies…but hasn’t everything at some point? 🙂

      Sounds like you’re doing a great job, paying attention to your little girl’s body language. Well done Mom! 🙂

  148. Hello,

    I am so glad to have found your site! I have a 5 week old son who suffers from horrible gas pains and is very fussy. He doesn’t cry that often but you can just see that he is uncomfortable most of the time. His poor little belly is so hard from he gas. Before I talk about the formulas I will say that I have tried everything else, burping positions, gas drops, gripe water, fennel seed tea, sleeping in incline, infant massage.. Nothing has helped. From the day he was born I was diagnosed with a milk production problem and was told that I would have to supplement with formula. As the weeks have gone by I have had to give him more and more formula to keep up with him. We started with similac advance. He was gassy after a week so I hired a lactation consultant to make sure it wasn’t a latch issue and a neighbor recommended gerber. My tried gerber soothe. I sent my husband to the store to get more and he came home with gerber gentle.. Not knowing there was a difference we tried the gentle for 5 days and gas was getting worse. We only gave the soothe two days. We then decided to switch and tried similac sensitive. The gas did not get better. We were then told to switch to Alimentum. My poor son’s gas did not get better after a week and there is now a rash all over his body. He has also started crying at night and doesn’t poop as often. He also has very dry skin. He had severe baby acne on his face which seem to turn into severely dry skin. The dr suggested that he has a milk problem and said to switch to soy. I really didn’t want to switch to soy but figured I wold try it to see if it helped. I hadn’t seen your article about how to switch so I didn’t ease him into it. We are a day and a half into it and it seems that a lot of his feedings he struggles to eat. He takes an ounce then struggles. Do you think it’s because of the quick switch or its not working? I really don’t want him to be on soy but want him to feel better. Any recommendations? I also want to note that I just cut out dairy. Should I pump and dump the little milk I produce for him for2 weeks as I have seen on here?

    1. Melissa, you and your hubby have certainly been through quite the “New Parent Initiation”! Just so I’m starting out understanding things…did you end up trying Gerber Soothe? Or was it only Gerber Gentle? (I totally can understand the confusion…took me forever to realize they were different! lol) Is your son constipated at all? Is he passing pebbles? Or is it just gas that’s making him so uncomfortable?

      The rash may be related to an allergy…As for the reaction to soy, it’s not uncommon for babies with milk allergies to also struggle with soy. (Not always, but sometimes.) So that may be part of the issue. Here are some options: (you may wish to run this by your doctor, just to make sure)

      1. Go back and give Good Start Soothe a try (unless I’m mis-reading your email) switching slowly. Give it a at least 5 days to spot any improvements.

      2. PureAmino is the next step beyond Nutramigen (which is another brand similar to Alimentium). It is based on amino-acids, so is extremely gentle, especially for very sensitive little GI systems. You can see it here on Amazon. Just in case you haven’t seen it, here are all the other very-sensitive colic formulas. You could also try Elecare, Neocate…there are several there that may help. Just remember, every brand is a bit different. For most babies that doesn’t matter, but for very sensitive babies it could make a big difference. So switch slowly, give it 5-7 days, and then move on.

      Definitely run all that I’ve said here by your doctor. Your doctor will know best. 🙂

      Regarding the breastfeeding, I would follow your instincts and pump and dump. That said, you may want to increase your pumping to every 2 hours or so to help keep your milk supply up. If you’ve already been diagnosed with a supply problem, you may have to increase that to every 1.5 hours during the day for several days at first. Talk that over with your doctor/lactation consultant as well. Pumping is a blessing, but with some mothers (such as myself) it’s not quite as stimulating as nursing and so can lead to a slow-down in production. That may not happen to you, but wanted to give you a heads up just in case. 🙂

    2. Hi Heather,

      Thanks for the info. We only tried the soothe for like a day and a half. I don’t remember if there was a difference. The stomach is worse now than it ever has been for the little guy so maybe it was better. We tried Alimentum but didn’t try nutragimen, would it be worth trying that first before moving to Pur Amino? I will run it all by the dr. The poor little guy woke up with worse skin today. He hasn’t been constipated really. This morning he had harder poop than normal and he couldn’t get it all out so I helped him out with it. But it wasn’t small pebbles. He definitely feels better after he poops. Ugh.. I feel so bad for my little guy. I just fed him the soy formula and he struggled through it.

  149. My son is 10 days old. He was crying for about 4 hours every night on Enfamil Newborn so we switched him 3 days ago to Enfamil Gentle Ease and he has been crying all day and all night with few periods of rest in between. Is it safe to assume the Gentle Ease has made the situation worse? Should I try something else or wait and see if it gets better? I would hate to keep him on it if it’s what is causing his issues.
    Thank you 🙂

    1. Jaimie, I would try starting over with Good Start Soothe. It’s very VERY gentle. If that doesn’t help, look through some of these hypoallergenic/colic formulas and try one of those. I would also make sure to follow the switching instructions so you can be 100% sure that the formula is working (or isn’t) and not that he’s having trouble with the transition. Give each formula at least a week (on it’s own) to see if you can notice changes. Just remember that everytime you try something and nothing changes, that’s not a failure. It’s just moving you closer to the target. It’s you eliminating options to get you closer to something that helps. (hugs!)

  150. Hi Heather –

    We had our baby on Enfamil Newborn at 2 weeks. She fussed some when she had gas, so we switched her to Enfamil Gentlease. The gassiness subsided a bit, but her poo was thicker than normal. We had read that might occur, so we didn’t think anything of it.

    Fast forward to her six week growth spurt. Her poo is now much thicker and drier, almost like drying plaster. Like, scraping it off her bottom thick. I assume this is because of the GI changes that happen around this time.

    She’s taken to screaming when she has a bowel movement or any sort of gas. It wakes her up, screaming, from a dead sleep, so she is only napping for maybe 20 minutes a couple times a day and spends her evenings SCREAMING bloody murder until she passes out, I’m assuming because she’s way overtired.

    My gut is telling me to switch her back to the regular Enfamil formula, because her stool was normal when she was on that, and the bit of gas she had was nowhere near as bothersome as what’s happening now. I figure it’s worth a shot, at least, since we still have some Newborn on hand.

    Thoughts? I appreciate your help!

    1. Liz, heartbreaking! I hate it when my kids are constipated. Such a helpless feeling. If your gut says to go back to regular, I’d go with that for a few days and see how it goes. Another option is to add a few teaspoons of prune juice (ask your doctor exactly how much, not sure her current age.) to each bottle until things loosen up, then cut back until you find the “happy place” where it’s just soft enough to avoid all the constipation issues, but firm enough not to cause tummy cramping. If that still doesn’t help, you can talk to your doctor about mixing in some Miralax. Do not do this without a doctor’s guidance. The dosage has to be just right. However, it can be a backup option to discuss with your doctor if things come to that.

      Hope this can help, Liz. (hugs!)

  151. My daughter is 12 weeks old.. Been solely breastfed..
    I have started supplementing with one bottle of formula at night just to get her used to it.. I’ve used enfamil “newborn” and she’s done okay with it.. Lastnight we switched to the “infant” because we ran out of the newborn.. Can said 0-12 months so figured it was ok… She did not drink it at all.. Cried and refused.. Does it taste different? Should I go back to the newborn even tho she’s nearing 3 months?

    1. Allison, you could try mixing 2/3 newborn and 1/3 infant and then slowly over a period of a week reduce the newborn amount. Also, some babies just prefer the taste of some brands over others. My favorite formula is Good Start, but Elena wouldn’t touch it – didn’t like the taste. So it really is trial and error. I would try to slowly get her used to the infant over a period of time and then if she still hates it, choose a different brand altogether. 🙂

  152. Hi!

    I have a 10 week old little boy, he was born 9 weeks premature and spent just over a month in the NICU. While there (around 4 weeks old) he started having unexplained bradychhardia episodes and an upper GI X-Ray was done and they determined he has mild silent reflux. We brought him home on Similac Neosure and adding 1 tsp rice to each oz formula. That has worked fine until recently. He has worked his way up to 3 oz each bottle and the rice has been making the formula so thick. And he’s getting constipated more often. He will only go maybe once a day or even 2 day and it’s obvious he’s uncomfortable. His poop looks like little round balls and is fairly firm. We tried backing down the rice but now he is spitting up a few times more a day. We have been thinking of trying the similac for spit-up. What do you think?

    Thanks so much!!

    1. I think that it’s worth trying! Also, you could add a teaspoon of prune juice to the bottle to help soften up those prunes. Ask your doctor about this first, though, just to make sure. With his previous health issues, I’d want him to confirm this suggestion. Hang in there Elana!

  153. My baby hasn’t been a good Pooper since switching to formula. Seems to really have to strain with each bowel movement that comes around every 4-5 days. She seems fussy at night but does generally okay during the day. I am using enfamil now. Do you think a sensitive formula would be easier for her?

    1. Kayla, I certainly think switching to a sensitive formula is worth the try. Good Start is my favorite brand (I’m not paid to say that, btw.) but every baby is different, so you don’t know how they will do until you try. You could also add a splash of prune juice to each bottle for a while and see if that helps soften things up. Constipation is so difficult to watch! It’s hard to see them suffering. Hope this can help!

    2. Okay. I was planning on doing that. I have been doing the prune juice and that definitely helps but the constant trapped gas is still there. While I was breastfeeding she was sleeping through the night (7-8 hour stretch) no problem at all. Since i stopped breastfeeding and doing formula she always wakes up around 3 am with trapped gas and stomach pains. I feel so bad! Would you recommend the good start “gentle” type? is that what it is called? thamk you so much for your help!

      -also when i do switch i will do the right ratios to gently switch her but do you do that with every bottle? thanks !

    3. Yep. Start with the Good Start Soothe formula. (I’ve linked it here on Amazon.) That’s the MOST gentle, so it should give us a good indicator if she’s okay with dairy or if a hypoallergenic is the next step.

  154. Hi Heather! I LOVE your blog. Please keep writing!

    We’ve been struggling with colic with my 10w old daughter since about week 5. We are talking all day & night colic – not just a couple hours at night. We have tried everything – first, per doctors suggestion we went to Nutramigen with no relief. Then, we put her on Zantac after about a week. That seemed to help for a while until she nosedived into screaming again. We adjusted her dose for weight and then found relief for a couple more days, but it was short-lived. In the meantime, we did everything else suggested, including changing to Dr. Brown bottles, feeding sitting up, Gerber Soothe drops (good reviews for those too), sleeping at an incline, gripe water, ect.

    Because of the success of adjusting the doses of zantac, i thought acid reflux was the real culprit…so i changed her to Enfamil AR. The first couple days of the change were fine because i stair stepped. I actually thought she was getting better with crying and actually sleeping better at night. Then i transitioned her to just Enfamil AR and she exploded. The crying was arguably worse than before.

    So, yesterday i changed formulas again. Because we had good results with the Soothe colic drops, i wanted to try the Soothe formula. I reread your article on changing formula and decided that i did not need to stair step because i was going from Enfamil AR to a more gentler formula (Soothe). I think i may have made a mistake. While she is definitely more calm and sleeping better, I did notice some major gas and burps. She is spitting up a bit more, but that is not my major concern as she is gaining weight and thriving, and it doesn’t seem to bother her. So my question is, should i have slowly introduced Soothe? She’s only had 4 bottles of soothe and i’m wondering if i should do something differently? Maybe the gas/burps are happening because she was on Nutramigen before, then a nutramigen/Enfamil AR mix for a couple days before I gave her Enfamil AR only (2 days was all i could handle).

    Let me know what you think. Thanks for your opinion!

    1. Diane, oh friend, colic parents are in a whole new league of awesome. You and your husband have my absolute respect. It’s the super bowl of parenting, and you are getting through it day, by day. Well done. Since you already tried Soothe, I would just grit your teeth and push through for the next few days. Give it at a week, if you can. If you don’t see improvement, I would try one of these hypoallergenic formulas – focus on the Amino Acid fromulas like PureAmino, Elecare, Neocate, etc. But definitely follow the switching instructions for those, just in case. Hang in there, Diane. We have a plan, so there’s hope! Let me know how it goes. Thanks for reading! 🙂

  155. My grandson is 3 months old. He was born about a month early but was still a good weight. He now weighs 13lbs and is gaining weight but he screams all the time even when being held. They have him on prevacid for acid reflux (he has mostly silent because he swallows it) and zantac for breakthrough acid. They also have him on Similac Alimentum. This baby screams so bad like he is in severe pain. He has had an upper gi to confirm the acid reflux but nothing is helping. He is so tired but will not sleep well. He sleeps sitting up in his vibrating seat, carseat or my daughters arms. She is exhausted. They have been living her for a little while and I have witnessed this first hand. It is never quiet around here. He has been switched between numerous formulas after much fighting with the doctor to switch him. The just keep saying he is fussy. That is not fussy when all your baby does is scream the whole time he is awake. He doesn’t smile but every once in awhile. It is so heart breaking to see how unhappy he is. Any suggestions would be greatly appreciated.

    1. Sharon, that is heartbreaking! I know you’ve tried a ton of different formulas – has your daughter tried any of the Amino Acid formulas? I talk about them in this article. I’m wondering if the Amino Acids (like PureAmino, Elecare, Pregesteril, etc.) would be easier for him to digest and cut down on the tummy troubles.

    2. Heather,

      I know she has not tried those yet. She also has not tried the Gerber Soothe so I think she is going to try that first. I will keep you posted how things are going and thanks so much for your quick response.

  156. My 9month old baby girl has been having some issues with her drinking her baby formula latley ..she is currently drinking geber gentle and vomits crazy .. I told the doctor shes rejecting the formula so I give he a mixture of juice and water the dr told me to just give her the formula as her only liquid …now she vomiting and has diarrhea ..could this be because of the formula

    1. Ashley – firstly let me double check you’re not using nursery water to mix in the formula. Did the vomiting and diarrhea start when you started this formula? or after? If she was on this formula and she was fine for a period of time, I’m guessing it may not be the formula, she could just have a bug. I would get her into the doctor right away. Dehydration is a very serious thing for babies (the #1 reason they are hospitalized) and with her vomiting and having diarrhea…I would call and see if you can get her seen ASAP to figure out what’s causing it. Keep trying to give her as much liquids as you can give her. At 9 months she can have water, so I would give her a teaspoon of water, wait 20 minutes to see if she throws it up, and then give her 2 teaspoons etc. But firstly, call the doctor and get her in to be seen. Bring her last poopy diaper with you, as they will probably want a stool sampled to test for rotavirus, trying to figure out what’s making her sick. Hang in there Ashley. Let me know how it goes.

  157. This is for Carrie, if she hasn’t found a solution yet. Our little boy was born almost 2 weeks late with growth restriction (they didn’t know until after he was born!) and had to be formula fed due to low production on my side, tongue tie, etc. etc…. He would scream constantly and seemed gassy all the time. I thought it was probably lactose intolerance as I have issues with milk, my husband is African and my son’s digestion was probably not up to par because of the IUGR. Our pediatrician didn’t agree, but told me to go with my gut. I hated the idea of soy, and said I would absolutely not give it to him, but also struggled with giving him table-sugar ladened formula that’s supposed to be easier to digest. I did end up finding Colief drops that have seemed to help. It’s like baby Lactaid to help in lactose digestion – all that’s in it is the suspended lactase enzyme that can be found in the human gut to break down lactose in milk. The second bowel movement he had after it smelled horribly of vinegar – a sign of lactose overload. He now has the drops with every bottle, and if we forget he screams. We also changed just recently to a DHA-free formula, while waiting for an order of Holle to come in the mail. We are just waiting until he’s six months (he’s 3 1/2 months) to switch to solids and goat’s milk/kefir and get him off dairy. Until then, he is doing a lot better with his “drops.”

  158. Thank goodness for this! You are so helpful! My 8 week old recently switched from enfamil ar to gentlease. (Old pediatrician said he had reflux, new pediatrician begs to differ and suggested we do gentlease bc he’s very fussy/gassy) on the AR he ate 6oz every 3 hrs and was fussy and gassy all the time. Now on the gentlease he only eats between 2-4oz randomly! Anywhere between 1.5-4 hrs. He was bornweighing 10 lbs so he’s a big boy weighing 16 lbs now at 8 weeks and has always eaten a lot until now. His stools have also changed from yellow peanut buttery to dark green and muddy. Do you think he just needs to get used to the gentlease? He has good wet and dirty diapers and is smiley when he’s up so idk what to do! It worries me that he’s eating 10-15 oz less than what he was!

    1. Martha, as long as he’s growing at a healthy rate I wouldn’t worry about the eating less. You can do a google search for “weight charts” or pick up a copy of the Milestone Marker to help you track that. It’s also possible he was eating more because he was spitting up, so it would take more to actually fill his tummy. I would give the Gentlease a solid week, and see if his fussy/gassy symptoms improve. If they don’t, give Good Start Gentle or Good Start Soothe. Fussy babies usually do well with Good Start. Let me know how it goes and if we need to come up with Plan B!

  159. Hi! I want to first say Your website is great!! So informative!! My 7 week old started on enfamil newborn, he became gassy and constipated so we switched to enfamil gentlease at 2 weeks! I was using the Walmart brand and he was still gassy so I thought it might could be the different name brands so went to exclusively enfamil. That was 3 weeks ago…once I started only enfamil he has a stinky, watery bowel movement after every feeding and sometimes 2! He’s crying bc of gas a lot too! He doesn’t have and extreme rash like other posts I’ve seen but he has a mild one….I was going to try the good start soothe to see if that worked better or I’m wondering if I should try a soy? I have to go back to work in a couple weeks and he has to go to daycare so I want to get all this figured out before then and also bc he seems to be in pain!! Just not sure which to try??

    1. Dallas! Thanks for reading! I’m very thankful it’s been helpful to you. I’m not sure soy will help you, since it’s very common for babies who are sensitive to dairy to be sensitive to soy as well. There is also some medical debate about soy formula, I’ve created the cliffs notes on that in this article.

      I would start with the Soothe for a few weeks and then use the soy as a backup. Some babies do well on soy, so you’ll never know unless you try!

  160. Question. Our 10 month old has been on Enfamil Prosobee since early on – her pediatrician recommended it for a potential milk protein intolerance. I also gave up all dairy as I was breastfeeding too. I reintroduced dairy awhile back, and she tolerated it well. But I have now weaned her completely. Is there any reason to continue with the soy based formula? I hate to be cheap, but if we can get her on something less expensive since she’s on formula only now, that would be nice…

    1. Abby, I would try a very gentle milk formula like Good Start Soothe and then just see what happens. Use the guidelines above for the switch, so you can be sure it’s really the formula and not the switching if she shows any struggles. It’s definitely worth the try!

  161. I just ran across your blog and I am loving all your information on formula! =) My 4 month old daughter is currently on Enfamil AR and has been since 3 weeks old (I was also nursing but had major milk supply issues and with her reflux she was spitting up every ounce of breastmilk so she is now on strictly formula). The AR has helped, but she still spits up throughout the day, however, not at night? She will only take 2-4 oz at a time during the day and yet will drink a full 6oz bottle at night and keep it all down? so weird! She really doesn’t seem to like the AR formula and she also has MAJOR sleeping issues (that’s another story all together) so I am debating swtiching her to Gerber Goodstart, which is what I originally had her on but then her Dr put her on the AR for the reflux. My 1st daughter was on goodstart and I loved it, so I have always prefered that. My question (yes, there is a question, it’s not just a bunch of random thoughts!) is do you think it would be ok to switch to a non-reflux formula like Goodstart? or since she is already on the AR does she need to stay on it? I just feel like AR is so hard on her stomach compared to a more gentle formula.
    Thank you so much!

    1. Erin, I think everything is worth trying at least once. 🙂 But instead of Good Start Gentle, I would recommend giving Good Start Soothe a try. It’s easier on the tummy and seems to work better for high-needs babies like yours. I would try it for a week and see if you notice any changes. Lots of babies start outgrowing the reflux around 4-6 months, so hopefully this will be a good time to switch! Good luck friend!

    2. awesome, thanks for the quick response! =) That was the other option I was debating so I will definitely try that! I assume I can just switch it without having to ease her into it?

    3. I would ease her for a day or two, just in case. That way you’ll know if she gets fussy that it’s truly is the formula, and not the switching. 🙂

  162. Question- I have been breast feeding my 4 week old son. We just found out he is struggling with digesting milk protein so I am on a non dairy diet. I have read that I should continue to breast feed while i wait for the dairy to leave my system…is this true? It seems cruel..he is so uncomfortable! Can I switch him to isomil for a few days( my other 3 drank it).. And just pump and dump for a few?

    1. That’s exactly what I would do, Meghan. As long as you keep pumping, that should help you keep your supply high. You may have to throw in a few extra nursing sessions at first in the beginning, or pump more often to keep production high, so keep an eye out for that in case. I’m sad to hear he’s struggling with the milk protein, but relieved that you’ve got some answers!

  163. My 8 week old just started having irregular bowel movementsast week. She will go up to 3 days without a bowel movement. Last night (being the 2nd day without a bowel movement), she started screaming and crying at the top of her lungs when I would offer her a bottle. I finally got her to eat 1-1.5 oz, she then went to bed and slept for 6.5 hours, when she woke up she would only eat 1 oz. At her next feeding 4 hours later I was able to get her to eat 4 oz. and she has been eating 3-4 oz most of the day. She also finally had a bowel movement (the consistency of peanut butter). She is on Similac Advance, and just tonight I am mixing bottles with Similac Senstive. She also has been very gassy from the beginning! I don’t know if this formula will help, but I can’t handle her not having bowel movements and not eating like she should. I have given her sugar water,& put Karo syrup (light) in her bottles both suggested that I do by her doctor! When I called the doctors office today they suggested I give her a suppository, but she had a bowel movement before I had to resort to that, which I really don’t want to do. I just want to find & fix the issue at hand! Any suggestions?

    1. Brittany, try adding some prune juice to her bottle. 1 teaspoon. That’s the first thing I would try. The second would be to switch to a Good Start formula like Gentle or Soothe. (And just for the record, in case any skeptics are reading this, I don’t get paid anything from Good Start, I just think they have the most gentle formulas on the market. :-)) I had to do all that with Bella – suppositories, the whole sha-bang, it’s a terrible feeling. Hang in there Brittany. If those things don’t work, let me know and we’ll try something else!

  164. I absolutely love this blog, you seem to really know your stuff so I am hoping you can help me. My dd is 4 weeks and was very gassy on similac sensitive, I took her to see her ped on Monday they diagnosed her with silent reflux, she doesn’t really spit up. She suggested I try good start soothe, we are on our 2 day of it and my daughter screams for hours after every bottle. It is awful, I keep hearing to stick with it for a week or 2 but it is so hard to see her like thelis. Could it just be her adjusting to it? Should I go back to the similac or try soy? I am so lost right now .

    1. Jennifer, I’m glad you’re enjoying the blog and finding it helpful. That just makes my day. 🙂 I’d love to return the favor…if she has silent reflux, I would give a thicker acid reflux formula a try. Usually reflux babies do better on those, since they are thicker and easier to keep down. Hope this can help! 🙂

  165. I need some advice!
    when my daughter was born she was on similar regular and was regurgitating and swallowing after with the arching back and crying. So we switched to GentleEase – all went well for two weeks but then her poop was so hard it cracked the skin on her butt and made it bleed so then we switched back to regular Similac formula. all was well for about 2 weeks and no more regurgitating but then she was having frequent, watery-mucos-y looking poops! Called the dr and was told to go to nutramagin. Now she is regurgitating again after her bottles and crying for hours. Really don’t know what to do here!! Any advice is appreciated!

    oh shoot – we also tried soy for two days and her poops were so hard they made her bleed again. that was right before we switched to nutramagin.

    1. Maria, I would give the Good Start formulas a go first. Perhaps starting with Gentle or Soothe? You can also add a teaspoon of prune juice to help soften up the poops. Poor baby! It’s so hard to watch our babies struggle with constipation. Hang in there Maria. Try Good Start and see how that goes. 🙂

  166. Hello I’m a first time mom. I switched my baby from enfamil newborn to gentlease because he was grunting,crying and didn’t have a bowel movement for 2 days when he was 2 weeks old. He’s now 3 months old and since I put him on the gentlease he has this diaper rash that doesn’t want to go away. Then I finally changed his formula to soy because I mentioned this to his dr. The rash went away but now I think my baby hates soy formula. I did it the way that u stated on the 3rd day he’s on the soy completely but I can see he’s drinking less and less w each feeding. He usually drinks 27 ounces in a day and he only drank 22 today.
    I’m wondering maybe I should give the enfamil infant a try? He loves milk but I’m afraid he will b constipated and miserable again if I give it to him. I just don’t want to go back to gentlease. I’m soo happy to see his butt looking normal and not raw and bloody for the past 2 months.
    I was looking at gerber gentle and was happy to see that the first ingredient was whey and not corn syrup. Is gerber gentle the same as enfamil newborn? Just wondering because I notice all the formulas that r for fussy and gas has corn syrup for the first ingredient. Can u recommend formula that won’t give my baby a diaper rash? Sorry for all the questions. Thanks

    1. Mel, firstly you’re doing a good job – trying new things to find something that works. It is entirely possible he doesn’t prefer the taste of the soy, so good job, mom, in noticing that he was eating less.

      I can’t tell you what your baby will react to, since every baby is different, but generally I’ve found Good Start to be the most gentle, better than Enfamil. I would give that a week and see if things clear up. If not, we can keep experimenting until we find the formula that works best with your baby. 🙂

  167. My son is nearly 4 weeks old. He was on Similac Advance from day 1 in the hospital. He had red splotches that I was told was baby acne from the beginning. Around a week old he became much more fussy and seemed to have a problem with gas. After much research I decided it wa likely he was mildly sensitive to milk proteins. So I switched him over, cold turkey, to Gentlease. He was instantly less fussy and his red splotches went away immediately. And within 24 hours I had a very happy baby. He’s been on Gentlease for about 2.5 weeks now doing awesome until the last couple of days – he began screaming an crying when having a bowel movement and it would be normal color but the consistency of modeling clay (so thick!). Otherwise a happy baby. He doesn’t cry much, he is gaining weight like a champ, no blood in stool (that I can tell), etc. Just a bloated, uncomfortable tummy, and having a hard time pooping. And again, this has only been the last couple of days. I take him to the doctor, expecting it to be just constipation and the doctor telling me to give him some juice or something but no, without examining him he immediately says to switch to a hypoallergenic formula.
    We can’t really afford the unless absolutely necessary. Plus, I feel it’s way premature to just jump to hypoallergenic formula.
    After his suggestion I decided it didn’t feel right to go that route so my husband and I thought we would try Similac Sensitive first then Gerber Good Start (going in order from least expensive to more expensive options for us). So, we switched him, cold turkey. It’s only been a few hours so its too early to tell what’s going on. But now I’m wondering, did I totally screw up switching him cold turkey? Should have I just waited it out a few more days on the other formula? Was this just a temporary constipation thing? I don’t know! And I’m so afraid I’m making/going to make te wrong choice and mess his little tummy up! Help!

    1. Firstly, I think you should give yourself a pat on the back. My “Mommysense” agrees with yours – that switching to a more expensive hypoallergenic formula without seeing if you can fix it in other ways seems rather drastic.

      Did you try the prune juice trick with the Gentlease? Switching cold-turkey isn’t going to harm him. It’s just a precaution. Some babies switch cold-turkey just fine, with know tummy side effects. So it’s possible your little guy will handle the transition perfectly. If he does seem extra-specially fussy, go back to a full bottle of the Gentlease and try switching him slower and see if that helps. Also, keep up with tsp of prune juice once a day and see if that helps with the constipation.

      Don’t be afraid of making the wrong choice, Erin. You’re a good mom. He’s a resilient, healthy baby boy. There are thousands of reasons a baby can be gassier than normal or constipated. The best you can do is guess around and try things, which is exactly what you’re doing. He may be uncomfortable for a while, but you’re working on it. He’s a lucky boy to have such a caring loving mama!

      I think you’re doing wonderfully. 🙂 Please feel free to comment back if you have more questions.

  168. Hello Heather. We have our baby on enfamil gentlease since she was 1 week Old, she is now 1 month and we want to change her formula to the enfamil for spit up because she spits up a lot and because her gas smells horrible and Dr said it could be the formula. I like the fact hat it is made with rice starch. I give my baby some of my breast milk too I give her 1.5 of my milk and 1.5 of formula. We tried the new formula today and gave it to her already twice but we did not do it slowly, we just switched and that is it. However she just had a big spit up and I wonder if it is because we did the change so quickly or because the formula is too strong for her. I want to continue giving her the new formula gradually, what do you recommend for me to do? Can I mix the old formula and the new and give her a different bottle with my breast milk?

    1. I think your mom instinct is spot on, Carol. Go back to what you were doing before and do that for a day. Then start the gradual switch over. Also, I think the idea to do a bottle with the new/old formula and another bottle for the breastmilk is also a good idea. Once you have her formula issues worked out, you can add in the breastmilk.

  169. I’m just reading all this good information you have given. So my 3 week old daughter has been supplementing with simalac advance and breast milk and today it’s full on formula. We switch her to simalac gentle bc our first one was on gentle formula and assume it was better. She has spit up a little and did not have a bowel movement today, mild fussiness if we lay her down( she wants to be held) so after reading about the different families should we go back to simalac advance and slowly switch to simalac gentle ? Or go back to simalac advance ? We also have good start but haven’t tried it. I want to use the best formula for her with less pain. I just want her to have regular bowel movements and try to avoid the consitapation. Any advise ?

    1. Missy, I’m so glad you’re finding the articles helpful! 🙂 You’re probably right about going back and switching slowly. It can’t hurt, and it will give you a better idea as to how she’s responding to the new formula. Personally, my favorite formula is Good Start. It’s the most gentle and tummies. I would try that. As for constipation, don’t use frequency as a guide for constipation. It’s possible for a baby to wait to poop for several days (especially when switching formulas), but not be constipated. The true test of constipation is consistency. If it’s thicker than peanut butter, that’s your clue that something’s slightly off. You can add 1 teaspoon of prune juice in her bottle once a day and then see how that affects her. Hope this can help Missy!

  170. Thank you so much for your help! Since i hve to keep trying this formula anything i can do bout the taste? By the way hes only 2 months

    1. Taste wise, I think I would just keep giving it to him and see if he gets used to it. Another option is to try a mineral water instead of tap water? Perhaps that could help?

  171. I called the pediatric gastro he sees for his reflux he says he thinks he has a sensitivity to the soy and milk protein so dont try then keep trying the hypoallergenic and if that doesnt work its either full hypo with the amino acid protein which is super expensive or he has to see a nutritionist that our insurance doesnt cover

    1. hmmm…if you have to switch to full hypo or amino acid, call the manufacturer and ask if they have any samples or special coupons or discounts you could use. Explain your situation and see if they will work with you in some way. It never hurts to ask. 🙂

  172. Hi with our son we started him right off on similac sensitive because my daughter needed it when she was a baby, both times my milk never came in. It was fine for a few weeks then he had diarrea screamed constantly wouldnt sleep eating habbit was crazy like an ounce every hour. We switched him to the lighter purple from similac that helps with protein problems recommended by our dr. Made it soo much worse. Finally we tried soy, worked for maybe a week or two well till today hes been constipated and slowly working back to the not sleeping wierd eating habits and constAnt screaming. Last resort is the similac hypoallergenic, the dark purple, first bottle of it tonight, not only does he obsolutely hate the taste after the first bottle he threw it up less than half hour later

    1. Hmmm… Okay so hypoallergenic is out. Have you tried Good Start Soothe? That is a more normal tasting formula, but is 100% whey, so a lot easier on the tummy. The other option is you could go back to soy, but then add a teeny bit of prune juice to the bottle to help with constipation (the amount will depend on your baby’s age.) Hang in there Alee! Try those things and then write back if you’re still having issues. We’ll figure out something!

  173. My Landyn is 4mths old. This is my 3rd child and by far my most difficult experience. I started breast feeding right away but he was tongue tied. After we finally figured that out and had it corrected he was eating great! His sleeping schedule is amazing and a little worry some for an infant. Since day one he has slept anywhere from 8-10 hrs at night without a feeding. Being he is my 3rd child I was not as adamant about waking him for extra feelings after I knew for sure he was progressing normally. My milk supply quickly became less and less because of this and I wasn’t pumping in between. Anyhow, at about 2-3 wks he became very fussy, gassy, Constant screaming. I thought for sure something was wrong with him. I cut all dairy and wheat out of my diet and that didn’t help. We saw a GI doctor who assured us everything is fine. Prior to that appt (I had to wait 3 1/2 wks to be seen) I switched from breast milk to Alimentum by Similac. He has done WAY better in this! I also have been giving him Gripe Water on a regular basis for at least 2mths. I have been told that this formula is doing nothing good/bad for him and that I’d be safe to switch to a standard formula that is cheaper since Alimentun is practically going to send us into bankruptcy…ok not really but it sure is expensive! After researching all diff types/brands I chose a formula called Holle. It is supposed to be the most natural formula in the world, even more so than organic. I have started the transition 1:3 yesterday and 2:2 today. Landyn is very gassy and has had multiple poops but I wouldn’t quite call them diahhrea. I would call them diff that what I’m used to and not sure really what to expect on this formula. Is it possible I’m going to quick with the transition since he’s gotten such bad gas? If this is supposed to be so natural I don’t understand how it would be so hard for him to handle? Am I doing the wrong thing here? Unfortunately I’ve done ALL of this, starting with switching from breast milk to formula, without talking to the pediatrician. He is a huge advocate of breast feeding and I just didn’t agree with him this time. It wasn’t working for me or for Landyn. So knowing he wouldn’t be supportive I did a lot of reading and talking to other parents and have made these moves on my own.

    1. Kristen, don’t feel bad about switching to formula. The fact that you breastfed your third at ALL is a huge accomplishment! The more children I had, the harder it was for me to breastfeed. 🙂 I haven’t heard about Holle formula, but I’m definitely going to add it to my research list, so thanks for mentioning it! You have to do what is best for your entire family, and sometimes that means formula. So guilt begone!

      As for your question, it sounds like you’re transitioning well. You could slow down and do 1:3 for 2-3 days, and then switch to 2:2 for a few days and see if that helps. It’s really hard to tell sometimes what is making a baby gassy. Even though it’s natural, different things react to different tummies in different ways. Many times you don’t know how things will work out until you try them. I would disagree with the person who said that Alimentum doesn’t do anything good/bad an you can switch to a different formula. Alimentum is designed for babies who have allergies – the proteins are extremely small and so are easier for babies to digest (less gas).

      If you want to move away from the Alimentum, I would recommend you switch to something like Good Start Soothe – it has a similar structure, but is a lot less expensive. That would be a good stair-step-down from the Alimentum towards a normal formula. Perhaps you could try using Soothe as a gateway between the two for a week or two, and then switch down to Holle? Just a thought. I talk about those formulas in my article on colic formula here. Hope it can help!

  174. I have a 4 month old and we had him on the Target brand of Similac. I recently got WIC and I am getting Goodstart now. I switched him over directly two days ago. The first day seemed ok but yesterday was awful. He cried all evening and was up alot last night. I didn’t know to ease him over by weening. So now I am trying the two formulas mixed to ween him over. Is it too late to do that? And if not, how long should it take for him to adjust?

    1. Normally, it’s not a huge issue to switch when the formulas are both based on cows milk, like Similac and Good Start normal formulas. That said, it does seem like you’re little one is struggling. I think you did the right thing mixing the two formulas together. If it doesn’t improve in the next day or two, I would go back to the Similac for a few days and try again in a little while. You could also try some Gripe Water to help with the gassy tummy. But I think your instincts were spot on! 🙂

  175. I’m going to be switching formulas due to financial issues. My 3 month old has been on Gerber good start since she was born and were going to be switching her to Enfamil Gentlease. I was told that they are the same type of formula but different name brands. Is that true? How do i start to wean her? She eats from 4-6oz in one feeding, how do i measure out the formula?

    1. Amanda, Every company has a different way of formulating the formula, so no, they aren’t the same. That said, both of their brands are based on cow’s milk, so switching shouldn’t be too difficult on her tummy. For the first few days, I would do 1 scoop of Good Start and 1 scoop of Gentlease in 4 oz of water. Do that for a few days, just in case she gets gassy at the switch. After a few days you should be able to switch straight over to the Gentlease. I believe it’s 1 scoop of powder for 2 oz of water, but double check that on the formula can. 🙂

  176. I am so glad I found this. HELP! My son is 6.5 months old. For the first 6 months we supplemented breastmilk (he never latched right so I pumped exclusively for 6 months) with formula. I’ll be honest–we bounced all over, though staying in the same family. I used Enfamil Premium for the most part, and some Similac Advanced. For most of the summer we started using the Sam’s Club brand, “Simply Right Complete.” We also started him on to solid foods, slowly as the pediatrician advised. Just about the time I stopped pumping and put him exclusively on formula (which we did do slowly!), his system seemed to go haywire. He was totally constipated, and then went to diarrhea and has stayed with A LOT of poopy diapers–most of his diapers are poopy every day. We might have one or two that are just wet. He also was refusing to drink more than 3 oz at a time when he had been calmly taking 6. I decided to pull back entirely and see if the formula was the problem, or if it was a food. So we’re back at square one with no solids, just using formula (simply right brand). He has started happily drinking more, but the diarrhea and a slight (really slight?) rash seems to continue on his little bum. I’m thinking I need to switch formulas but where do I go from here? Some of the Gentle kinds you suggest? Will that clear up the constant poopy diapers? We’re seriously flying through diapers and wipes over here!!

    1. Tara, a constant poop cycle is exhausting! :). I would start with Good Start Gentle, see if that helps. If not, you could try Good Start Soothe. Start with those and give it a few weeks to see if you notice a change. Good luck!

  177. I have 12 week old twin girls. They were born 6 weeks early. Around 7 weeks they were diagnosed with acid reflux by their pediatrician based off of symptoms I explained to her which were: spitting/throwing up after almost every feeding, fussines, gassiness, arching of back and screaming during feedings. She was going to prescribe medication for acid reflux but when a discrepancy occurred with the pharmacist and the dosage prescribed, their ped called the NICU Dr. to double check on the dosage and was advised to have us switch to enfamil AR with no meds because meds have not shown a significance in helping reflux. So we went from enfacare (they needed the extra calories because their preemies) to enfamil AR. They went from feeding 4 oz. every 3 hrs to eating 4-6 oz. of AR every 2 hrs. Most times they would fall asleep during the feeding and then wake 30 min later to feed again. It seemed like they were feeding all day! One girl stop spitting up completely after feeding while the other would only a little and it was curdled, but the fussiness was just the same. ( Basically if they aren’t sleeping, eating, being burped, being carried, or bounced in their bouncy seat, their crying) So called the doctor and she said we could try gentle ease, we did and helped with the spit up but not the fussiness and they seemed more gassy. So I tried Similac sensitive and it got even worse, they started drooling and gnawing at their hands and the fussiness was the worst. So went back to gentle ease trying to stick it out because I read it can take up to 2 weeks. They were only drinking 1-2 oz’s and skipping feedings. I became concerned so I put them back on AR which we have been on for the past 2 days again ( 3 weeks the first time.) The doctor refuses to give us meds and said that we can try a hypoallergenic formula such as nutrimegen. But the cost is way out of our budget ( we don’t qualify for WIC). We wanted to be sure that we exhaust all options before having to get a part time job to afford the hypoallergenic formula. I know this is a loooongggg post but any advise? Oh one more thing, I still give them about 3 feedings of enfacare at night because they drink it all at once without screaming, they don’t seem to throw up or even need to be burped while their sleeping and it holds them over longer. Could this be conflicting with the other formulas actually working?

    1. Laurie, having one high needs baby is exhausting. Having two…? Well, you are amazing. This will improve. Keep your head down and keep surviving. You’re doing great.

      I don’t think you need to worry about the formulas canceling each other out. Enfacare is in the dairy-based formula family, so you should be able to switch around with gentlease, etc. without too much trouble.

      1. If they do well on Enfacare, what if you continued using it all day? It is good for preemies up until 9 months. Good Start Nourish is also for preemies, so may also be a good option.

      2. Good Start Soothe is very close to a hypoallergenic. It’s not 100% lactose free, but the proteins are as small as they can get. The problem with this is that it’s thinner, so I could see your babies spitting it up. Perhaps worth the try, though.

      3. Perhaps try a different thickened brand of formula. So instead of Enfamil AR, try Similac Sensitive for Spit Up(different than Similac Sensitive).

      4. Finally, you could continue with Gentlease, just try to address the extra gas with something like Gripe Water.

      Those are the things I would start out trying. I hope it can help! You are being such a good mom. In a few weeks they’ll start rewarding you with more smiles and giggles. It’s coming!

  178. Our 6 week old has been through so many formulas, I’m beginning to think I should have continued fully Breastfeeding! I read your blog about lactose intolerance versus a milk allergy, and my husband and I still can’t seem to figure it out! When we first started supplementing, we were using Enfamil for Infants. He was projectile vomiting it seemed, a vast majority of what we were feeding him. So we then proceeded to switch him to Enfamil A.R., which was a big mistake! He cried for days from being so constipated and his throw up was so thick I was scared he’d choke on it. We then switched to Similar sensitive, which seemed to work great, until he started getting a little on the runnier side of poo. We are also on WIC, and the only kind of formula they allow for WIC approved is Gerber. So we transitioned to Gerber good start Gentle. He now cries a lot, & is awake more from crying and having hiccups. & has the worst diarrhea I have ever seen! ): at this point we were thinking of seeing a doctor. I just don’t know what to do, or even what to think. Is it a milk allergy, a lactose intolerance, or are we switching formulas to abruptly & his tummy is taking the toll? Did I mention, he is covered from forehead to ankle is little bumps that feel like heat rash. We were told that’s normal, because of summer & maternal hormones. I still question his rough bumpy skin, and the reasoning behind it. I fear it could be eczema, or an allergic reaction. Please help!

    Sincerely, one concerned mommy!

    1. Wow Morgan! You seem to have hit them all! I do think you should talk to a doctor, this is above my brain level. Those bumps sound a lot like eczema, but have your doctor check that too. I wish I could be more helpful. But it really sounds like your baby needs to be examined and a physician consulted. Good for you, though, for pursuing answers! Keep trying different things until something sticks. 🙂

    2. One other thing that I forgot…I just did this for my 6 yr olds eczema, so you could try this: right after you bathe her, rub her all over with Aquaphor (you can get that at CVS, Target, or Walgreens). It looks like Vaseline. It will trap the water from the bath inside her skin cells and help prevent those itchy bumps. 🙂

  179. Our 8 week old has had a bad time with gas over the past 4 weeks and we switched from Similac Advance to Similac sensitve to lactose about two weeks ago, and she initially seemed to do better and her baby acne cleared up too. Near the end of the first week on the formula, she was showing the same gas pains and screaming in distress, so I took her to see the physician that was covering for her normal doctor who told us she has colic. My husbands mother urged us to switch to soy as it helped our nephew when he had colic. We have been on Similac Isomil for 5 days and while some of the colic symptoms have decreased, she doesn’t always have a full feeding and is constipated. She had regular poops on the lactose sensitive formula, so I am wondering if she will continue to be constipated on soy or if she will start to poo normally when her body gets used to it. It’s heartwrenching to see her in this much pain, I am wondering if it better to go back to the lactose sensitive formula and deal with the colic instead of dealing with reduced colic symptoms and constipation. Help!

    1. Anne, I agree, it’s heartwrenching to see a baby struggle with constipation. Before you give up on it, try adding a little prune juice (1-2 tsp) to the bottle and see if that helps. Another option is to switch to a different low-lactose formula or hypoallergenic. Gerber has a formula that is as close to hypoallergenic as you can get before actually paying for an hypoallergenic. I mention it in this article. Hope this helps!

  180. HELP!!!! I took my baby to the Dr yesterday and she said she has eczema and it could be due to a milk allergy. To give her soy formula till I could get the dairy out of my system. I pump and give it to her by bottle. I have supplemented formula with her a couple times and she has taken it fine other then the fact it taste different. Well I gave her the soy formula late yesterday afternoon up until this morning and she has done nothing but cry and its a painful cry! I have been giving her gas drops band rubbing her belly but nothing is helping! What should I do?! She’s only 3 months too BTW don’t know of that will help knowing or not.

    1. Kayla, there are lots of reasons babies can have eczema beyond just a milk allergy. There are two things that come to mind: 1. Switching to a soy formula requires a “Stair step” approach to get your baby’s tummy used to the new soy protein (instead of the milk). So perhaps the switch was too fast and that caused the tummy troubles? or 2. The eczema could be due to something else. I would perhaps try a gentle formula for basic allergic reactions and see if that helps at all. Read about those here. Hope this helps, otherwise comment back and we’ll try something else. 🙂

    1. Candi, you are a good parent!! You are looking for answers, and you obviously CARE, so that makes you an AWESOME parent in my book. 🙂 Breastfeeding isn’t always a walk in the park, and sometimes it just doesn’t happen. If you want to keep trying, I would pump every 2- hours for a few days. That was how I kept my supply up during these transition periods.

      As for the formula, some babies handle abruptly switching from milk to soy without any tummy troubles. If your baby doesn’t seem to act like her tummy is gassy and she’s uncomfortable, don’t worry about it. If she DOES, then switch back and go the slow route. That should help.

      Again Candi, YOU ARE DOING AWESOME. You are the PERFECT mother for her, and will do the right thing. Let me know how it goes and if I can help in anyway. (hugs)

  181. Hi, ok so our dr told us to try a soy based formula. Our LO has been having runny poops some diapers so our dr said she may be intolerant to the formula. We are using Infamil Gentlease. We have neen supplenting breastmilk with formula. Each feed has been 2oz BM/1oz F. NOW we bought soy based formula but now I am not producing enough milk to make the transistion. I know you posted that you must transition when going to soy to milk based, do you have to when its milked based to soy? I would guess so, but my dr just said to switch. Since she is intolerant to the milk based I figured to stop giving her that since she gets runny poops from it. So tonight I gave her 2oz BM and 1oz soy based formula. I only have one more feeding left of BM (long story) and now really nervous about switchig to soy so abruptly. What should i do? I am so nervous and have been through hell the past 4 weeks trying to get something that works for her since breastfeeding didn’t. Please help. Next feeding I am thinking of doing 1oz BM and 2oz soy based formula. I am not mixing the soy based formula with the milk based for she doesnt tolerate the milk based one. Why make her double sick right? BTW she only drinks about 3-4 oz each feeding and she is only 4 weeks old. Thank you and SO trying to be the good parent BUT this is so hard. Especially when the breastfeeding plan failed miserably! 🙁

  182. I have been using both breastmilk and formula since he was born as I was not producing adequately and he had trouble latching. The hospital gave me Similac for him and I used that for the first 2 weeks but now that my WIC for him went through, we get Enfamil for him, and he doesn’t seem to be adjusting well. He has been throwing up I think…at least 4 times since he started on it two days ago and it’s rare for him to be able to down more than an ounce or two at once. I don’t know what to do. We can’t afford the Similac, and he can’t seem to digest the Enfamil. What do I do? Any advice is welcome.

    1. Victoria, Let me help you get the bottom of this, okay? First of all, the WIC website says this: “State agencies are required by law to have competitively bid infant formula rebate contracts with infant formula manufacturers. This means WIC State agencies agree to provide one brand of infant formula and in return the manufacturer gives the State agency a rebate for each can of infant formula purchased by WIC participants. The brand of infant formula provided by WIC varies by State agency depending on which company has the rebate contract in a particular State.”

      Which state are you in? I want to help you triple check the state’s policies and see if we can find either loophole for the Similac or another brand other than Enfamil you can try.

      Don’t worry friend, we’ll figure this out. (hugs)

  183. My 4 month old has been showing signs of a milk allergy, blood in her stool. We have been using Gerber Good Start since birth, supplementing breast milk. Our Dr recommended switching to Similac’s hypoallergenic formula. We tried the new formula tonight, prior to reading your info, and switched directly to the Similac. She was not having any parts of it! We had to toss the bottle and just give her the Gerber. Is it common for babies to totally reject the new formula if not eased into it? I’m nervous that if I try the 3:1 then 2:2 ratio, she will still reject it.

    1. It is common Chelsea, so don’t worry. 🙂 My 2nd preferred the taste of some formulas over the taste of others. (Funny that they have such preferences so early on!). This is especially common with hypoallergenic formulas, since those have a very different taste than regular formulas. Perhaps do the 1:3 ratio for a week, then the 2:2 for a week, etc. If she STILL is rejecting it after this slooooow process, try it again with a different hypoallergenic and see if that helps. That way she has a longer period of time to adjust to the taste difference. Good luck!

  184. My 5 week old has been on enfamil gentlease since 2 weeks old. No reason just what the pediatrician gave us. We found out Friday he has acid reflux. Spitting up at every feeding. Zantac since then. Today is Monday still spitting up so he switched him to enfamil AR. No instructions. But his poop has gotten a little thicker already. I just switched didn’t “go slow”. I assume they are in the same “formula family”. But idk. Am I doing it right?

    1. Mary, I would say they are close cousins, so you are probably fine. Both are Enfamil brands, which mean that the underlying formula is the same, with little tweaks for different issues. (Switching from a Good Start to AR may have caused tummy trouble…it depends on the baby, but it’s always better to be cautious)

      AR is very good in helping babies with reflux, but if he doesn’t seem to improve much you may want to look at these other acid reflux formulas as back ups.. Switching from AR to one of those can also be done quickly, since they are in the same formula family. Hope this helps!

      Heather 🙂

    2. My 4 week old was switched to nutramigen yesterday due to the fact the she was very fussy and gassy currently on gentlease. The dr told me to switch right over and she has been throwing up and spitting up worse than ever. She also has acid reflux and is on Zantac but that seems to be worse too because she is spitting up and getting chocked on the acid in her stomach. I feel like the switch was a little much because I am not sure she even has a milk allergy and the nutramigen seems a little extreme. Should I try something else to help with the fussiness and gas that will cause her to have more than one bowel movement a day? I am so desperate for some help! My dr told me to try one ounce of the nutramigen per hour until I build up volume, but that sounds crazy to me too. What should I do? My gut is telling me to try good start or something similar.

    3. Carrie, I would go with your gut for a few days and see what happens. It can’t be any worse than it is right now? Usually with acid reflux, I would recommend starting with one of these pre-thickened formulas. If that doesn’t help, go with Good Start Soothe, and then transition slowly back over to Nutramigen and see what happens. If he gets constipated, add a teaspoon of prune juice a few times a day. I would also weigh him every day (or at least every other day) to make sure he’s gaining weight.

    4. Ok, so I ended up going back to the gentlease and adding rice cereal, but I truly believe she is lactose intolerant. The spitting up is gone (which is great) but she has diarrhea every time she eats and her bottom is paying the price! My doctor’s office truly will not help me make a decision. Is soy my only option? I have been reading about soy so naturally I am scared to death of it now! Could she just need a lactose free formula? Should I give soy a try? This is just so frustrating and I want her belly to feel better so much! Thanks!!

    5. Sounds your instincts may be right about the lactose issue, Carrie. You have two choices, as I see it. #1) Pick a soy formula. Which may or may not help, lactose intolerant babies can still react to soy. Still, it may be worth trying, since it’s cheaper than the alternative. #2) Pick an amino-acid hypoallergenic formula. I share those in this article discussing colic formulas. Elecare or Neocate would be examples.

      I know you’re frustrated, but there is a silver lining to all this. 🙂 Instead of having 54 different things to try…we’ve narrowed it down to two. And I’m confident one of these is going to work. Keep in mind that you may have to hand-thicken these to counteract the spitting up with a sprinkling of rice cereal. There’s a light at the end of the tunnel, Carrie. Hang in there!

  185. So, i just switched my baby’s formula from i guess the “regular stuff” to designed for gassy/colicky babies. She’s not AS gassy, and she poops more often than she used to, but good lord, she cries ALL THE TIME! If she’s awake, she’s crying. We’ve tried gripe water, which is supposed to help with colic, we’ve given gas drops, i swaddle the crap out of her, I’ve tried everything. Do you think maybe we should look into a soy based formula? Could excessive crying be a sign her formula isn’t working out?

    1. I don’t think it would hurt to try switching for a while and see if that helps. Does she seem MORE fussy after feeding? or does she act like she doesn’t want to eat? If so, you could have a silent reflux issue on your hands. Otherwise, I would go ahead and give soy a try. Earplugs helped my husband and I a LOT with our EM. Takes the edge off the constant screaming. 🙂

    2. I have a question . My daughter is 8 months old and I’m giving her Infant Enfamil wich is through 12 months but I got 3 cans that I got for free qnd they are Enfamil Newborn through 3 months . Will this cause something wrong or anything ?

    3. Cielo, newborn formula is especially designed for that age range. I’m sure it isn’t recommended, because of the age emphasis, but you’ll need to talk that over with your pediatrician. It’s not something I’m qualified to give advice on. 🙂
