Best Glass Baby Bottles Of 2020

All parents want the very best for their babies, and so choosing the safest and most reliable products that are available to us is important. Choosing the right baby bottles is especially important, as these products are in contact with our little-loved ones several times a day.

Below, we have discussed why parents should consider using glass bottles instead of plastic and have reviewed the five best glass baby bottles currently on the market.

Why Glass Baby Bottles are Safer Than Plastic

While many people turn to plastic bottles for convenience and lower prices, they should be aware that the plastic options may pose a health risk to their infants. To ensure that plastic bottles are durable, manufacturers construct many of them with hard polycarbonate plastic. Polycarbonate plastic is stronger than other plastic types but is known to contain the chemical BPA.

According to experts on the Livestrong website, BPA is dangerous for everyone but is especially of concern when ingested by infants and young children. The chemical has been linked to hormonal imbalances in children and acts as a form of estrogen once it enters the body. In high enough amounts, this can begin to cause issues with a baby's development over time.

Baby bottles are frequently heated up with milk already inside of them, and the addition of heat allows for the chemical BPA to leach out of the plastic faster and in greater quantities. For this reason, glass baby bottles are the safer option for parents to consider. Glass is naturally free from BPA and comes with its fair share of other advantages that we will discuss below.

Other Advantages of Glass Bottles Over Plastic Bottles

It is important to keep baby bottles clean and sterile for the safety and health of our little ones. For this reason, glass baby bottles are superior to their plastic competitors. Since glass can hold up to extreme heat better than plastic, these bottles can be boiled for sterilization without warping in shape or leaching toxic chemicals. They are also easy to rinse out and keep clean than the film on plastic bottles.

Additionally, glass bottles last far longer than plastic ones overall. Many plastic bottles will warp after too many washings, sterilizations, or falls. Many of us find ourselves needing to replace these bottles frequently, which can become an annoying expense on top of diapers, formulas, toys, clothes, and other baby accessories.

However, glass baby bottles will last for years to come, saving parents money in the long-run. It is easy to get away with only having a few of these high-quality bottles at home, even throughout future pregnancies.

​Another advantage to choosing glass over plastic bottles is the environmental impact. Glass bottles are completely recyclable, while many plastic bottles are not because of the polycarbonate materials.

Even if a glass bottle becomes chipped or a parent no longer needs it, it offers some peace of mind knowing that the bottle won't end up taking up space in our landfills for years to come.

​How to Choose Glass Baby Bottles

There are a few things that parents should keep in mind while shopping for the right glass baby bottles. For safety reasons, the durability of the bottle should be of importance to parents.

While most glass bottles are made with tempered glass that is pretty resistant to cracking and breaking, all glass does pose the risk of breaking if dropped hard enough.

Even a small chip in the glass could create a sharp edge that a baby, or even a parent, could cut themselves on. One way to play it safe is to look for glass bottles that are protected with a layer of impact-absorbing silicone or rubber.

Another thing to look for while choosing the right glass baby bottles is the item's weight. Glass is already a lot heavier than plastic, which makes dropping bottles a possibility for small children.

Buying smaller bottles may help with this. It will require more refills of the bottle, but the cut in weight and bulkiness comes in handy. This is also perfect for parents who carry around an already stuffed and heavy diaper bag.

Finally, parents should look for a bottle with a nipple that is suitable for their babies needs. Bottle nipples come in different sizes for different stages of growth and development.

While these can be easily swapped out after purchase, it is important to know that not all nipples are compatible with all bottles. Vented nipples, which help reduce gas as your baby drinks, are often made specifically for a certain brand and size of the bottle.
