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 (especially the benefits of glass baby bottles). I’ve read thousands of reviews across a ton of different websites, plus looked at bottles at the top retailers and asked some friends. Here’s what I’ve found on glass feeding bottles.
Best Glass Bottle for Babies
Evenflo Feeding Vented Plus Glass Clear Bottles
This one bottle wins the best glass baby bottle for feeding formula 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.
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 Evenflo Feeding Vented Plus Glass Clear 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. (Don’t forget to read our Best Formula article for our in-depth formula reviews!)
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
Chicco NaturalFit Glass Baby Bottle
I actually have a tie in the best glass bottle for breastfed babies 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. But first, here’s the super-popular Chicco glass baby bottle.
I think these Chicco NaturalFit Glass Baby 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
- Nipple collapses sometimes during feeding
- Not as durable and easily break if dropped
Philips Avent Natural Glass Bottle
This one is my second favorite in the best glass bottle for breastfed babies category. I have used Avent bottles before for nieces, nephews, and siblings, and even a few times for my own kids. These glass versions certainly don’t disappoint.
These Philips Avent 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
Joovy Boob Glass Bottles
Joovy makes a plastic bottle aptly named the boob, and it has many fans among us parents. This is the glass version of that bottle, and it’s just a great of a feeding bottle.
There’s not much to brag about with the glass bottle itself. It doesn’t absorb odors or tastes like plastic. It has a basic, ergonomic design that makes feeding easy. A major plus is that this sturdy galss bottle is recyclable for when you are done with it.
The Joovy Boob glass bottle is available in 5 ounces and 8 ounces, with measurements printed on the sides. You can also buy silicone sleeves in 4 different colors for the exterior to help keep a better grip on it. But like all glass, treat it with care, or it will break. Since this glas isn’t tempered, it’s easy to break or crack.
As for the nipples, this bottle works with the Joovy Boob nipples. These are designed with twice baked silicon for extra softness and feature a wide and deep design that encourages a more natural latch. You can find it in 5 flow rates, ranging from preemie (don’t forget the Best Preemie Formula!) to X-cut (which is extra big). The Joovy boob is resistant to yellowing, tears, and bite marks.
This bottle uses Joovy’s CleanFlow vents, which nest into the rings of the bottles. This patented technology works so that no matter how the bottle is tipped, there’s a hole for the air to release. This reduces gas and colic in bottle fed babies.
The three piece system (vent, ring, and nipple) is easy to wash, but it’s kind of a pain having the extra piece (the vent) to put on. And if you don’t do it in the correct order every time, it’ll leak everywhere. That’s only a big deal in the middle of the night, when you can’t remember who you are or what day it is and all you know is that baby is hungry.
One downside of the Joovy glass feeding bottles is that they aren’t compatible with the Joovy insulators and Dood sippy cup accessories like the Joovy plastic bottles are. Still, you get the same awesome nipples and accessories, so I’ll say it’s still a win.
What I Love
- Thick glass with printed guides
- Ergonomic shape and silicone covers
- Wide neck is compatible with Joovy Boob nipples
- Patented venting technology works every time
- Natural nipple for better latch
- Available in 3 stages for the right flow
What I Don’t Love
- Glass is prone to breaks, chips, and cracks
- Extra vent is a pain to keep track of
- Not compatible with the insulators or Dood sippy cups
Lifefactory Glass Baby Bottles
I didn’t think a list of glass baby bottles would be complete without this product. It’s the pioneer and leader of the silicone covered glass baby bottle world.
The glass of the Lifefactory Glass Baby Bottles is made from a super quality and durable glass called borosilicate glass. It resists thermal shock, so if you accidentally put a cold bottle from the fridge under boiling hot water to warm, it won’t shatter. The completely clear and dishwasher safe bottles are available in 4 oz and 9 oz.
The narrow opening of the bottle makes it compatible with most major breast pumps, which is a huge bonus!
The outer is surrounded with a silicone cover. The holey design means that both you and baby can find a good grip nearly anywhere. It also means that no matter how you drop it, it’s insulated and protected as best it can be. This silicon is dishwasher safe too, so you won’t have to remove it prior to washing.
One thing I don’t like about having the silicone cover on the whole thing is that the printed guidelines suck. There are few ounce markings, but no milliliter markings. Plus they are hard to read. Some veteran bottle maker parents probably won’t mind, because you know the overall capacity of the bottle and you can guesstimate. But I like to know how much water/formula baby is getting with each feeding, and I really, really don’t want to have to measure that out separately before I make a bottle. Because that’s just ridiculous.
The Lifefactory nipples here are nothing to brag about. They’re a BPA/BPS free, phthalate and lead free, and FDA approved silicone in a classic nipple shape. They work fine, but you’ll have to get the right nipple size for the best flow rate. Also, not venting means lots of air. Not a great option for gassy or colicky babies.
A feature that I love about Lifefactory Glass feeding bottles is that they are compatible with the nipples, the flat caps, and the sippy caps. These bottles, if cared for well, can really be used for years and years because they grow and adapt with your child.
What I Love
- Classic bottle shape with amazing silicone sleeve
- Thermal shock proof glass can take a temperature beating
- Compatible with most major breast pumps
- Regular nipples made from safe materials
- Work with the sippy cup lids
What I Don’t Love
- Size guides printed on the sleeves is not ideal
- No venting = lots of gas
Glass vs Plastic Baby Bottles: 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 (which defeats the purpose of buying the best organic formulas, am I right?)
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 feeding 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 feeding 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’ve thrown 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.
