The Best Glass Baby Bottles for New Parents in 2021

These glass baby bottles are worth toasting over.

In This Article...

There’s a reason so many parents are searching for the best glass baby bottles.

  • They are better for the environment (in production and in recycling capabilities)
  • Glass doesn’t absorb smells
  • They don’t stain over time, extending their use for years
  • You don’t have to worry about chemicals leaking into your baby’s formula or breastmilk during the process of warming or reheating
  • Sometimes they can be less expensive than many plastic brands!

In 2018, the AAP released a statement of concern about the amount of chemicals that are either added directly to food or come into contact with our baby’s food via plates bowls and… can you guess? … bottles.

The best glass baby bottles completely remove that concern! The issue now, though, is which bottle should you buy? Here are the top five best glass baby bottles, detailed for different categories so you can compare.

2 Must-Read Tips for Using the Best Glass Baby Bottles

Before you jump into the comparison chart, though, let me offer a few tips on using these bottles.

Tip #1: Sterilizing Needs to Happen

Yes, you can use the dishwasher, but you will need to make sure to run it with hot water and a hot dry setting. See more tips on this from CDC.

If you don’t have a dishwasher, or prefer to keep your glass baby bottles separate from the stroganoff you had for dinner last night, a good sanitizer/steamer will do the trick.

Most bottle brands also have their own sanitizer, but I prefer to get one that will fit with ALL bottles, because my kids are snobs and the bottles Lauren liked, Elena hated, and I didn’t want to buy more than one expensive sanitizer. This is the general sanitizer most parents like most.

Tip #2: Remember…Glass Isn’t Plastic

First of all, glass breaks. It will happen eventually, although if you choose a bottle with borosilicate glass that “eventually” may turn out to be 10 years. Either way, if at all possible, purchase a silicone sleeve to keep pieces from ending up everywhere.

Secondly, glass is heavier than plastic. Even though the neighbor boy is holding his own bottle at six months, your baby may need a bit more time to lift the heavier glass on his own.

Finally, glass is a better conductor of heat than plastic. This means that it may heat up faster than you were expecting. Keep a close eye on things in the beginning, until you get a feel for the warm times, and don’t forget to test that milk/formula on your wrist before handing to your baby!

Detailed Reviews of the Best Glass Baby Bottles

Best Overall

Avent Natural Glass Bottles

Avent Natural Glass Bottles also have the borosilicate glass that the Lifefactory uses, but these are less expensive because they do not come with the silicone sleeve. It has to be purchased separately and comes in green, blue, pink, and white. A fabric sleeve is also available.

These bottles use the same Airflex vent technology of the regular plastic Avent bottles which has been designed to reduce colic by venting air away during sucks.

To avoid leaking, parents need to make sure you line the nipple notch with the cap notch to make sure the nipple is secured properly. (This is an important step that is easily overlooked!)

Things Parents Rave About

  • Fewer items to sterilize
  • Fits directly into Spectra pump
  • Borosilicate glass
  • Less expensive

Things Parents Complain About

  • Doesn’t come with a sleeve
  • Have to line things up carefully or will leak
  • Customer Service
Most Durable

Lifefactory Glass

The Lifefactory glass baby bottles have proven to be the most durable, with a silicon sleeve that protects your baby even IF the glass were to crack. It comes in trendy colors like kale, papaya, mango, and mint.

The glass is thermal shock resistant borosilicate glass, which is fancy for saying “tough as nails”. You can take this bottle straight from the freezer into boiling water and it still won’t break.

You can also purchase a sippy cup top when your baby gets older, which guarantees these bottles (which are a bit pricier than others) get years of use!

Things Parents Rave About

  • Toddlers can still use with sippy top
  • Can leave sleeve on in dishwasher
  • Borosilicate glass
  • Adaptable to most breast pumps
  • Trendy color options

Things Parents Complain About

  • Measurements on sleeve only
  • No preemie nipple available
  • More expensive than others
Best Anti-Gas

Dr. Brown’s Glass

Dr. Brown’s has been the best anti-colic bottle for the past decade, helping millions of fussy babies feel a little better after eating. It’s no surprise, then, that his glass bottles are just as effective as the plastic ones.

You can purchase these bottles in 5 oz and 9 oz sizes. The 5 oz size comes with level 1 nipples and the 9 oz comes with level 2. (The higher the level, the faster the milk will come out of the nipple.)

Sleeves for these bottles are available for purchase here. You can choose from blue, mint, and pink.

Things Parents Rave About

  • Effective with gassy tummies
  • Wide-neck makes adding formula easier
  • Glass is contoured for better grip

Things Parents Complain About

  • Multiple parts to wash
  • Sleeve is purchased separately
Best Value

Evenflo Premium Vented Glass

The Evenflo bottles are the best economical option, since they tend to be the least expensive glass bottles on the market. You can choose from a variety of glass color besides clear, including lavender and teal.

There are no sleeves available to purchase with these bottles and silicon sleeves (at this time) not available. Also, these bottles are not made of borosilicate glass, so you will need to avoid taking them from extreme cold to extreme heat, or they may break.

Things Parents Rave About

  • Very inexpensive
  • Fits most breast pumps

Things Parents Complain About

  • Narrow top — harder to clean
  • Not borosilicate glass
  • No sleeves available
Best for Breastfeeders

Nuk Simply Natural Glass

The Nuk Simply Natural glass bottles have shown to be particular effective in helping babies switch from breast to bottle. An 2019 independent market research study of 203 moms showed 96% of breastfed babies would accept this bottle as an alternative.

The nipple design is extra-soft with multiple holes that provide a more natural breastfeeding-feel. There is a scooped nipple cavity that allows space for baby’s tongue and jaw to move naturally.

Things Parents Rave About

  • Very easy to clean
  • Lighter than other brands
  • Innovative nipple design

Things Parents Complain About

  • Shape can be difficult for babies trying to hold on their own
  • No silicon sleeves available
  • Not borosilicate glass
