Possible microplastics are a concern for many, and that extends to baby bottles. If you're looking for a plastic-free option that's highly heat-resistant and durable, consider one made of glass! It won't hold on to odors and can be fully sanitized without melting.
However, glass baby bottles come in many different shapes and sizes, so choosing a product is not an easy task. If you need some options, check out our list of favorites! Philips Avent's Natural Glass Baby Bottle won our grand prize. It's durable as well as heat-resistant, so you won't have to worry about damaging it if you want to sterilize with hot water. There are eight other options where that came from as well as a buying guide full of tips to help your shopping experience easier. Read on for our other favorites, as well as a buying guide that was reviewed by a pediatrician.
In addition to being good for the planet, glass baby bottles can also be better for your baby. You don't have to worry about the chemicals used to make plastic leaking into your baby's milk or formula.
In addition to being BPA-free, glass bottles are also free of any retained odors. Nobody wants an old, plastic bottle that smells like musty milk or formula, and with a glass bottle, you can use boiling water to ensure the inside is sterile and odor-free.
It's true that glass bottles are a lot heavier and more breakable than plastic models. However, they do last longer as glass doesn't break down over time as plastic does. And, when you're finally finished with them, can be recycled to reduce your carbon footprint.
In addition to reviewing our buying guide, Dr. Hardin was kind enough to recommend her favorite glass baby bottle.
|Nipple type||Breast-shaped, vented|
My favorite glass venting system is the Dr. Brown's wide neck bottle. I love the affordability and potential for longevity as the vent can be removed if the baby outgrows it.
This is the perfect choice for the new mom who's breastfeeding and wants to have the option for an interchangeable, affordable, and flexible system.
Finding it tough to choose a glass baby bottle? Don't worry! In this buying guide, we will discuss all the things you should keep in mind while picking a glass bottle, including the type of glass to look for and the nipple shape that will promote a natural latch.
Many glass products are made of soda-lime glass, which is prone to breakage and can't withstand sudden temperature changes. This means that a soda-lime glass bottle will break if it’s chilled in the fridge and immediately heated up in the microwave.
Borosilicate glass, on the other hand, can withstand temperatures of up to 340 degrees Fahrenheit. For reference, most glass baking ware is made of borosilicate glass. You should still take care when handling a borosilicate glass bottle after it's been heated, however, as it will be very hot.
Another important safety feature of borosilicate glass is that it doesn't break as easily as soda-lime glass. Due to its chemical make, borosilicate is less brittle and more shock-resistant. If by chance a borosilicate bottle does break, it does so in rounded pieces as opposed to the dangerous shards soda-lime glass breaks into.
One notable difference between soda-lime and borosilicate glass is that borosilicate glass is very clear. Soda-lime glass has a bluish-green tint.
Most glass bottles are made with reinforced glass, which helps to decrease the risk of injury. Furthermore, if a glass bottle breaks, instead of sharp edges, the pieces will be more rounded than sharp. They'll resemble smaller pebbles.
The shape and the flow rate of your bottle's nipple determine how smoothly the formula or breastmilk flows into your baby's mouth.
Breast-shaped nipples present a very wide base and a soft, pliable tip. Often, this tip will be long and flattened on one side to mimic the shape of a mother's breast when it's pumping milk.
The wide base makes it easy for your baby to latch on in a wide-mouthed, natural way. Breast-shaped nipples are good for fussy babies or babies who are transitioning away from breastfeeding.
Oval-shaped nipples, also known as standard nipples, are another good option. Just make sure that you're buying an oval-shaped nipple with a wide enough base to support your baby's full latch.
Bottle nipples that don't transition from base to tip gently enough may impede your baby's feeding. Your baby may only suck on the nipple's tip, resulting in a poor latching technique. If you notice that your baby's mouth isn't wide open and resting on the base of the nipple, you may need to find a new nipple style.
Both breast-shaped and oval-shaped nipples work well to prevent too much air from entering the baby's stomach. Round nipples are not breast-like, which makes it harder for the baby to form a good seal.
You want a nipple shape that makes an easy transition between breastfeeding and bottle feeding. This can also create more opportunities for dads to participate in the feeding and bonding process.
Level 0 nipples are aimed at babies who were born prematurely. Preemie babies encounter issues like choking while they feed, so be sure to bottlefeed your little one under the supervision of a nurse if you're unsure about your bottle's nipple.
Level 1 nipples usually fit newborns to three-month-olds. Level 2 nipples tend to work for three- to six-month-olds, while Level 3 is often preferred between six months and nine months. Level 4 bottle nipples are for nine-month-olds and up; at this age, you won't have to worry about the nipple's shape as much.
These are just the general guidelines, so check with the manufacturer for the specifications. If your baby seems to struggle to drink out of the bottle, the flow is too slow. So, you should move up a size. But if there's milk running down their cheeks, the flow is too fast. So choose a nipple with a faster flow rate.
Your baby's comfort while feeding is important. There are other factors to consider in addition to the baby's age when deciding on the flow of a bottle's nipple.
Oftentimes, your baby can help you decide when it's time to advance the type of flow. If you notice crankiness, your baby might be working too hard to maximize the flow, meaning it'll be a good time to size up.
It's important to prevent your baby from swallowing too much air as they feed, as this can cause gas and discomfort later on.
If your baby gets fussy after mealtime or seems to have some tummy issues, try investing in a glass baby bottle with a vented nipple system. These nipples are also called anti-colic nipples. While there's no proven method to fully prevent colic, a vented nipple has been known to ease the symptoms in colicky babies as well.
A nipple with anti-colic vents helps redirect air into the bottle while keeping it away from your baby's tummy. It will reduce the chances of getting colic, gas, or other stomach discomfort issues. This venting system also prevents the nipple from collapsing.
A venting system is needed to help prevent a vacuum from forming in the bottle. A vacuum makes it harder for the baby to pull milk from the bottle. Venting helps but in the case of swallowed air, the baby's stomach may feel firm or bloated and result in more spitting up.
The most common materials used to make baby bottle nipples are silicone and latex. Latex is naturally yellow in color and has been in use longer. Unfortunately, latex can also be an allergen in rare cases and it picks up odor over time. Still, latex is soft, durable, and closer in texture to human skin.
Silicone, on the other hand, is clear and more aesthetically pleasing. While it isn't known to cause allergies, silicone isn't as soft or durable as latex. Nipples made of silicone may cause breast confusion in fussy babies. Still, silicone nipples are easy to clean and don't retain any unpleasant odors.
Both materials have good points to them, and deciding which is best for your baby may take some trial and error. As a pointer, though, your baby may be a better fit for latex nipples if they're fussy about transitioning from breastfeeding to the bottle. Silicone is a good choice is you or your baby are sensitive to smells.
If your baby will hold the bottle, keep in mind that glass is heavier than plastic and might be hard for your baby to hold onto. So choose a bottle that contours to fit your baby's hand. Some baby bottles feature a twisted design on the glass that easily allows your baby to hold the bottle.
Many bottles come with a silicone sleeve that promotes a secure and firm grip. A silicone sleeve can help protect the glass bottle from breakage, too!
Some bottles also come with removable handles that offer an easy grip for your baby. A silicone sleeve and handles will also protect your hands from getting burnt while holding the warm bottle.
To help you with your search, we've curated this list of the eight best glass baby bottles. They're all made of durable glass and have useful features to help your baby have a pleasant bottle-feeding experience.

We've answered some commonly asked questions about glass baby bottles, and Dr. Hardin was kind enough to offer her input as well!
Dr. Hardin says, "When cleaning your baby's bottles, start with cleaning your own hands. You can then disassemble the bottle, run under soapy water, and finally air dry on a clean rack.
Bottles should be sanitized daily, especially for babies under three months. Other cleaning options include cleaning the bottle in boiling water or using the dishwasher set to hot or sanitizing mode."
It's best not to warm your glass baby bottle in the microwave, even if it's made of borosilicate glass. This is because the high-power heating method of a microwave will unevenly heat the milk inside your baby's bottle. This could lead to burns in your baby's mouth at worst, and half-chilled milk at best.
Instead, heat some water on your stove and put the filled bottle into the water. Check the milk on your wrist until it reaches the right temperature. You can also run hot water from your faucet over the bottle, although this is less water-efficient.
