Plastic Free Baby Bottles: Why You Should Switch

Have you considered switching to plastic free baby bottles? Almost all common baby bottles on the market are plastic, and they are popular for good reason. They’re cheap, unbreakable, and convenient. However, more and more studies are finding that plastic isn’t safe when it comes into contact with food and drink. Let’s discuss.

Are plastic bottles dangerous?

In 2012, the US Food and Drug Administration (FDA) banned BPAs, a type of plastic that has been shown to leach chemicals into food and drinks, from plastic sippy cups and baby bottles. While this was a good step forward, other forms of plastic are still dangerous. 

BPA, or bisphenol-A, is just one form of bisphenol. Other forms of bisphenols are still allowed in the making of baby bottles. Bisphenols mimic reproductive hormones in the body, which can negatively impact fertility, puberty timing, body fat, the nervous system, and the immune system

Apart from the chemical risk, there’s also a risk of microplastic consumption. Sippy cups and plastic baby bottles are often made of polypropylene. In a recent study, this type of plastic has shown that it sheds millions of microplastics into whatever liquid it contains. Although we don’t yet know the health effects of microplastic consumption, it’s better to lead with caution.

“As a new mum, I felt enormous pressure to keep my baby safe, healthy and happy. I was completely overwhelmed and exhausted, and then to discover years later that those feeds I gave my son had potentially thousands of microplastics leached into each bottle of milk was disturbing. The more research I did, I realised that the act of making up a bottle alone wasn’t the only opportunity for microplastics to be introduced into my baby’s feed. At nearly every stage of cleaning and preparing a bottle, there was potential to release thousands of microplastics into my baby’s milk. With my first child, I combination fed him for over a year, and it dawned on me that even when I was pumping breast milk, that milk would have come into contact with microplastics in various ways before even hitting the bottle. From being emptied into a plastic pump that had been sterilised to then being reheated in its plastic storage bag – these are all processes that have been shown to produce hundreds if not thousands of microplastics. I made the decision with my second child to switch to glass and stainless steel bottles, and I have to say that they are 100% better quality. I’ve even found special offers and deals to make it more economical than plastic.” – Lucy Sheinman
