Best Glass Baby Bottles and Why You Should Go Old-School

by Michelle Hand |

Are old school glass bottles better than contemporary plastic ones?

If you decided to ditch plastic and go for old-school glass baby bottles, you have shockingly little in way of variety. So which glass baby bottles are the best glass baby bottles? I think that Evenflo Feeding Vented Plus Glass Bottles are best for formula babies, while Chicco NaturalFit Glass Baby Bottles or Philips Avent Natural Glass Bottles are best for breastfed babies. These choices have a lot to do with the nipple design and functionality, as well as quality.

I spent a lot of time researching glass baby bottles. I’ve read thousands of reviews across a ton of different websites. Here’s what I’ve found.

First: Why You Should Give Glass to a Baby

Giving glass to a baby might seem like a terrible idea. After all, plastic seems so soft and safe. But have you ever thought about what’s in that plastic? And have you considered the fact that your baby is drinking from that plastic multiple times a day for a few years on end?

Such a realization might lead you to research plastic little more, like I did. While most baby products are made without the use of BPA, a known toxin that once was included in a lot of everyday baby gear, that doesn’t mean that your baby’s plastic bottle is completely safe. It might still contain small plastic hard particles that are breaking down and leaching into baby‘s milk.

Another health issue with plastic is the difficulty of actually using it. Although it might say you can, you really shouldn’t be microwaving or dishwashing your plastic baby bottles. It wears them down and increases the risk of chemical exposure. Plus, plastic has the bad habit of hanging on to odors and bacteria, much more so than glass.

And if you breastfeed and give the milk to your baby, you’ve no doubt experienced the frustrations of having the fat separate inside the bottle. In a plastic bottle, this fat sticks to the side of the bottle and doesn’t want to mix in. That doesn’t happen with old-school glass bottles.

And whether you breastfeed or formula feed, you have probably noticed that your plastic bottles get an icky film on them. That’s because that plastic is holding on to the fats in the milk. That’s also why they get that weird film over time- the plastic is retaining foods and cleaning agents alike, making the bottle look dirty.

Beyond the possible health implications of plastic, there’s the environmental implications. Think of how many bottles you’ve probably used for your baby. If you’ve used them a lot, they’ve no doubt eventually stained, warped, scratched, or just become ugly, and you throw them out.

Once a baby bottle is thrown out, do you know how long it takes for it to decompose? It takes 450 years for your typical plastic water bottle to decompose, and some of these thicker and more compound plastics, like is probably found in your baby bottle, can take up to a thousand years to decompose!

Glass is awesome for the environment because it offers reusability to the max. One set of glass baby bottles can probably last you years, and certainly though your baby’s entire feeding journey. Plus, when you’re done with the bottles, they are 100% recyclable. And glass recycling is much more easily accessible than plastic recycling.

Bottom line: Glass is better and is actually recommended over plastic.

Best Glass Bottle for Exclusively Bottle Fed Babies

One bottle wins this category, hands down. It gets consistently wonderful reviews. After looking at it myself, I like it a lot because it seems sturdy. And it’s cheap, too.

Evenflo Feeding Vented Plus Glass Clear Bottles

The Stats

These shapely bottles are made from a lead-free tempered glass that can withstand extreme temperatures (i.e. your fridge and your dishwasher). You can purchase the 4 ounce size to start, and then graduate to an 8 ounce bottle. You can also purchase these glass bottles in classic clear glass, or tinted teal or lavender, if you’re feeling fun.

The twisted design of the bottle makes it easier for parents and babies to hold on to during a feeding. It provides a better place to grip. It also allows all of the liquid to drain out easier without splashing down when tilted. There are molded glass ounce and milliliter markings on the side for easy mixing and measuring.

The included neck rings and caps are made from plastic that is PVC, phthalate, and BPA free. These are standard bottle size, which means that these bottles will work with most other pumps or nipples on the market.

The nipple is made from silicone, which softer and easier for baby to use than latex. It’s also got the Pro Venting technology, which helps reduce gas and colic. The vent is integrated into the nipple so that it’s all one piece. This vent helps the nipple to not collapse during feedings, while also helping to direct air bubbles into the bottle and not into baby’s tummy.

What I Love

  • Very inexpensive, yet well made
  • Vent works well to make baby less colicky and gassy
  • Molded glass measure markers can’t wash off over time
  • All materials are safer for baby
  • Compatible with all standard neck bottle accessories and pumps
  • Parts are easy to clean and sanitize (dishwasher safe)
  • Tempered glass is seriously tough to break

What I Don’t Love

  • Twist design isn’t that comfortable and makes buying a silicone sleeve difficult
  • Can be hard to get neck on tight enough to avoid leaks
  • A bit heavy at just over 9 ounces for the 8 ounce bottle


Best Glass Bottle For Breastfed Babies

I actually have a tie in this category. These two glass baby bottles are nearly interchangeable, with just a few differences. Both are great for a breastfed baby who needs to take a bottle here and there.

Chicco NaturalFit Glass Baby Bottle

The Specs

I think these bottles get less attention because they aren’t one of the big feeding brands, but they are amazing. They’re made of a lightweight, thinner glass. They feature a ergonomically shaped bottle with an indent that makes it easier to hold. These bottles also come in unique sizes. It comes in a 5 ounce size and a 9 ounce size, versus the traditional 4 and 8 ounce bottles.

These bottles comes with a bonus silicone sleeve. This silicone sleeve helps to improve your grip on the bottle, shields you and baby from getting burned, and offers additional protection in case you drop or roll it. The sleeve also has a cut-out design so you can still see how much liquid is in the bottle by using the printed measure markers.

The two bottle set includes one angled slow flow nipple, one straight slow flow nipple, as well as a cap and a silicone sleeve. These silicone nipples are BPA free and fit the wide mouth bottles.

The nipples that come with this set are fantastic. They’re called NaturalFit nipples, and they’re designed to have a natural-feeling movement that mimics a breast. Since they’re wide mouth, they have a wider base that will help encourage a natural latch. The silicone is also textured to help baby to keep the latch and not take in extra air. The nipple has dual anti-colic valves to move air out of the bottle. The slanted nipple is awesome because it mimics the natural shape and angle of the breast, making it ideal for interchangeably breastfed and bottle-fed babies. In fact, a recent study showed that 96% of babies latched on immediately when given this bottle!

What I Love

  • Glass is lightweight, at only 10 oz weight for the 9 ounce bottle
  • Included silicone sleeve is wonderful
  • 5 and 9 ounce sizes mean more room to mix, stir, and fill
  • Nipple angle and design seriously mimics the breast
  • Wide opening makes it easier to clean
  • Angled nipple is better for newborns and sleepy babies
  • Tight seal means no leaks
  • Thinner glass warms more quickly

What I Don’t Love

  • Expensive!
  • Nipple collapses sometimes during feeding
  • Not as durable and easily break if dropped


Philips Avent Natural Glass Bottle

The Specs

These Natural glass bottles are made from a tempered glass that’s both heat and thermal shock resistant.  It’s actually called borosilicate glass, and it’s pharmacy-grade, super pure glass with zero lead. The bottles have an ergonomic shape to help make bottle feeding easier on your and your baby. They’re available in both 4 ounce and 8 ounce sizes.

The design of this glass bottle features a wide neck for increased user-friendliness. There’s a measurement guide printed on the side to show you exactly how much liquid is in the container.

The Avent glass bottles include the bottles, caps, rings, and nipples. The plastic used in these bottles is a polypropylene (PP) plastic. It’s BPA free and dishwasher safe. The bottles are compatible with all Avent Natural products, like other wide neck nipples.

The wide-based nipple mimics the breast so that breastfeeding babies latch easier. The nipple shape also mimics the breast and has built-in comfort petals, which help to make the nipple more flexible and softer. These petals also help the nipple to keep its shape during feeding, so it doesn’t collapse. The nipple features two anti-colic valves that release air back into the bottle and not into your baby’s stomach.


What I Love

  • Glass is easy to heat and can be dishwashed and microwaved
  • High grade glass is not easily broken
  • Wide neck makes cleaning and heating easy
  • Parts disassemble easily for quick and thorough cleaning
  • Nipple doesn’t collapse during feedings
  • Soft and shaped silicon mimics the breast for smooth transitioning
  • Faster flow nipples mimic real let down

What I Don’t Love

  • Over 10 ounces of weight for the 8 ounce bottle means that it’s heavy
  • Rings and nipples get leaky after a few uses
  • Bottle shape is awkward to hold for an extended time
