Glass Bottles: Advantage & Disadvantages

In time past, glass bottles were considered unsafe because of the risk of them breaking and hurting the baby. These days, however, glass bottles are made of specially tempered glass that does not break easily. On the off chance that these bottles break, they form small pebbles instead of the sharp glass shards that could hurt your little one. 

Let’s not get too ahead of ourselves. Below, we will explore the pros and cons of glass baby bottles.

Glass Baby Bottle


Chemical and Toxin Free

Your little one’s bottle is an essential aspect of your baby’s care; thus, it is essential to consider its safety. Unlike plastics, glass bottles are 100% natural and free from harmful chemicals and toxins. When you pick a glass bottle, you can be sure that toxins like BPA, Phthalates, and PVC are not leaching their way into your baby’s milk.

Stain and Odour Resistant

Glass bottles do not pick up or retain odors and colors like plastic bottles. So, you can be sure that your baby is getting unflavored milk and nothing else. 

It Has A Longer Life Span and is Recyclable

Glass baby bottles last longer than plastic bottles, provided correctly handled. The longevity of glass bottles makes for a slightly higher cost; you can use them for years. Since glass is made from materials found naturally in nature, it can easily be recycled or reused. This is a plus for eco-conscious parents. 

Durable and Easy to Clean

Unlike plastic bottles, glass baby bottles pick up fewer scratches. Thus, it is easier to detect when they are dirty. Glass bottles are also far ahead of plastic bottles when it comes to durability because they can withstand high temperatures. Thus, you can sterilize your glass bottles in steam sterilizers and boil them.

Retain Its Shape

Glass bottles are very resilient and retain their shape in harsh conditions. You will find that glass bottles do not become mishappen when subjected to heat, unlike some plastic baby bottles.


Glass Bottles Weigh More

Most people complain about the weight of glass bottles. The extra weight means the bottle is tougher and more durable. However, it also means you have to contend with a heavier baby bag during your runs. Add that to the ever-increasing weight of your growing baby, and it may be a bit too much for you to manage.

Glass Baby Bottles are More Expensive

With glass bottles, the higher quality translates to extra cost. Looking at the cost of the bottle alone, you may get discouraged. However, consider it to be an investment, especially as the bottle has the propensity to outlast your baby’s sucking phase.

Plastic Bottles: Advantage & Disadvantages

You will find more plastic bottles in stores today for several reasons. Plastic bottles made after 2012 are safe for babies because they do not contain harmful chemicals like BPA and PVC. Thus, you needn’t worry your head so much about the quality of the bottle.

In subsequent sections, we shall explore the pros and cons of plastic bottles. Let’s get down to it, shall we?

Plastic Baby Bottle



Plastic bottles are readily available in retail stores across the globe. Perhaps, this is one of the reasons why they are so much cheaper than glass baby bottles.


Another upside of plastic bottles is that they are lightweight and unbreakable. Thanks to this, they are the practical choice for baby bottles. You can take them out of the house without them shattering on the asphalt.


Plastic baby bottles are less expensive than glass bottles because they are less expensive. Of course, the fact that the raw materials needed are also readily available has a part to play.


Gets Dented Easily

Unlike glass baby bottles, plastic bottles get scratched and dented easily. These scratches impact the clarity of the bottle, thus making cleaning harder. So you will need to change the bottles more often than glass bottles. The scratches on the bottle also serve as a breeding ground for bacteria.

Loss Shape 

Plastic bottles are not as durable as their glass counterpart. They tend to become mishappen and need to be changed.


Plastic bottles cannot withstand high temperatures and are not suited for the cold temperatures of the freezer. So, you cannot sterilize them in boiling water or chuck them in the microwave. Some plastics lose their integrity once specific sterilization methods are employed.

Not Eco-Friendly

Plastic bottles are not eco-friendly. They can take almost 450 years to decompose and so is not a favorite of eco-conscious parents. The sad thing is even with recycling, most of the plastic material still ends up in landfills.

Pick Up Odors and Taste

Unlike glass bottles, plastic baby bottles tend to absorb flavors and odors with time. These smells and tastes can impact how your baby sucks from these bottles. Once your plastic bottle starts to pick up smells, you should plan to change it.

What to Look Out for When Picking Glass Baby Bottles

Before choosing glass baby bottles, there are some things to consider. Top on the list is the quality of the bottle; for that, we recommend sticking with brands you can trust. Questions to consider include:

  • How heavy is the bottle?
  • Is it durable?
  • Does it break easily?
  • Can it withstand extreme temperatures?
  • Does it come in different sizes to match your baby’s changing needs?
  • Does it have anti-slip features?
  • How well does it fit in your hand?

Bonus Tip: How to Select the Best Baby Bottle

1. Nipple Design

When choosing a bottle for your breastfed baby, it is essential to consider the nipple flow. Bottles with slow-flow bottles work best for breastfed babies since they mimic the natural flow of breast milk. However, some wide nipple bottles work well for breastfed babies. Choose a bottle with a narrow neck and a soft nipple that allows slow milk flow into the baby’s mouth.

2. Material

Great baby bottles are made from either plastic or glass and are made from food-grade materials. For ease, select a lightweight bottle that your baby can hold up easily. Ensure the bottle is BPA-free and has none of the harmful chemical components common in bottles today. If you choose to opt for a glass baby bottle, make sure it is shatter-resistant.

3. Compatibility with Breast Pump

For ease, select a baby bottle that you can connect to your breast pump so that you don’t need to worry about transferring the milk or formula from one to the other. Today, most glass bottles are compatible with breast pumps and can be stored in the freezer to preserve the extracted milk.

4. Durability

You will need to select a bottle made from high-quality material and durable. That way, you can enjoy your money’s worth before ditching the bottle. If you select a premium glass baby bottle, you can use it for your baby and pass it off to the next nursing mother at the end. 

5. Bottle Size

Just like clothes, baby bottles come in different sizes. So, it is vital to choose a baby bottle suitable for your baby’s age. Another option is to choose bottles that come in different sizes to save cost. 

6. Cost

Of course, nothing good comes cheap. Thus, you may need to shell out some extra money to get a great baby bottle. You can go for affordable baby bottles within your budget range. Remember, sometimes, the price has no bearing on an item’s quality, so look for a good deal.

Final Thoughts
