Picking out baby feeding bottles can be challenging if you’re new to the whole parenting journey. Not only is there a wide range of brands to choose from, but there’s also the choice of glass vs plastic vs silicone. With silicone bottles becoming all the rage, you may be wondering about the silicone baby bottles pros and cons. More importantly, are silicone baby bottles safe?

Silicone baby bottles are one of the safest types currently available. Constructed from food-grade silicone, they don’t contain harmful chemicals such as BPA, microplastics or phthalates. They are also lightweight and unbreakable. The only drawback is that they are generally more expensive.

Key takeaways

  • Silicone bottles are made from medical-grade silicone, making them super safe
  • They are designed to mimic mom’s breast, making the transition between breast and bottle easy
  • Simple to clean, sterilize and freeze

Are Silicone Baby Bottles Safe?

Yes! Many new parents will be delighted to learn that silicone bottles are considered to be the safest baby bottle option currently available. Since they’re flexible, toxin-free and easy to clean and sterilize, they make excellent alternatives to stainless steel and glass options. 

Why are Silicone Baby Bottles Better?

One of the features that make silicone bottles better is that they look and feel natural. Many silicone bottles mimic the mother’s breast, making it easier for babies to transition between breast and bottle. Furthermore, their flexibility makes it easy for babies to hold and get used to. 

Silicone Baby Bottles Pros and Cons

As with all other baby products, silicone baby bottles have a series of pros and cons that parents should consider before making the final choice. Some of the more prominent pros and cons are listed below. 


  • These bottles contain no BPA or chemical toxins
  • Safer and much more durable than plastic
  • Easier for breastfed babies to transition between breast and bottle
  • Safe to place in boiling water, microwave, sterilizers and dishwashers
  • Wide neck design makes them easy to clean


  • Can fall over if almost empty as the base is made of silicone
  • May leak if the plastic ring is not tightened correctly
  • Shouldn’t mix formula in the bottle as the bottle isn’t sturdy

How to Pick the Best Bottle for Your Baby

When choosing the best bottle for your baby, consider the following:

  • Opt for at least two types in case your baby doesn’t like the one you chose
  • Always have an anti-colic bottle on hand for any potential anti-colic symptoms
  • Choose BPA-free options
  • Select bottles with minimal parts to make cleaning quick and easy
  • Dishwasher and microwave-safe options make sterilizing easier
  • For glass options, always choose shatter-resistant options

Are Silicone Baby Bottles Better than Glass Bottles?

Glass bottles have always been a popular choice because they don’t leach toxins and also don’t harbor bacteria. However, as hygienic as glass bottles are, they are also the heaviest option. This can produce a challenge for tiny hands trying to hold their own bottles. 

Is Silicone Safer than Plastic for Babies?

The use of older plastic bottles has been discouraged by medical experts because of the BPA content. Modern plastic bottles may advertise that they are BPA and phthalates-free, however, research has shown that even modern plastic bottles contain a considerable level of microplastics. Silicone on the other hand is made with medical-grade silicone, making them safe to use. The only advantage plastic has over silicone is that plastic is the cheapest bottle type.

It’s always easier to highlight the differences between bottle types when you can view their features side by side. Here’s a comparative table highlighting the key features.

Silicone Baby Bottles vs Plastic Bottles

Because of the no BPA factor, silicone bottles are safer than plastic bottles. They’re also easier to handle and don’t retain odors. 

Silicone Baby Bottles vs Glass

Silicone bottles are better than glass because they’re lightweight and easier for babies to handle. There’s also no risk of the bottle breaking if it falls on the ground.

Silicone Baby Bottles vs Stainless Steel

Stainless steel bottles also don’t contain any BPA, making them an equally safe option. They are however not as easily available as silicone bottles.
