“Glass baby bottles? Are they really a thing?”

We heard you ask this question, and yes, they are – and they’re becoming more popular by the day. There are lots of reasons for parents choosing glass over plastic for their baby’s bottles, and we wanted to find out more. Are they safe? Are they better than plastic? Which ones should I buy? Read on to find out everything you need to know about glass baby bottles.

Are glass baby bottles safe?

One word: yes.

When you think of a glass bottle, you probably think of a milk bottle, which shatters dangerously if you drop it. Considering how many times you and your baby will drop their bottle – we know how clumsy you get on 3 hours sleep after all – you want to make sure that a glass baby bottle can withstand babyhood. Plus, the initial thought of giving your baby something made of glass can make you shiver.

However. The glass used to make baby bottles is extremely hard-wearing and safe. It’s tempered and therefore toughened; they’re also thermal-shock resistant, meaning they can go from freezing cold to piping hot without breaking. This is great if you’re taking stored baby milk out of the fridge in the bottle to be warmed up. Think of your Pyrex dishes that you use for casseroles – it’s the same sort of treated glass.

Glass bottles are also really easy to clean, and don’t store dirt or bacteria in the way plastic can.

If you’re worried about glass bottles slipping out of your grasp easily, you can buy special sleeves to give you extra grip.

Are glass baby bottles better than plastic?

You will have heard of BPA (bisphenol A), which we’ve been avoiding in plastic goods for a long time. This chemical can leach into drinks and food, so it’s always vital to make sure any bottles, plastic lunchboxes, or bags are BPA-free.

However, given the discover of this chemical, who’s to say there aren’t more nasties hiding in plastic that we don’t know about yet?

Using glass as a material for your baby’s bottle removes all worry about chemicals leaching into their milk, as it’s naturally free of toxicity.

Plus, if you’ve noticed how plastic can begin to smell over time, you’ll be glad to know this won’t happen with glass. Plastic traps dirt and bacteria, whereas glass won’t.

Are glass baby bottles eco-friendly?


Your glass baby bottle will last much longer for you and your baby; plastic bottles often cloud and scuff over time, whereas your glass bottle will stay shiny and clean forever. So no more throw-away plastic; plus, glass can be recycled properly, and won’t live forever in our oceans after you’re done with it.

Should I buy a glass baby bottle?

That’s really up to you and your preferences. There are pros and cons to both glass and plastic baby bottles, and every mum you talk to will have an opinion on them. Choose a bottle that suits you and you’re baby, and you’re winning.

If you’ve decided you’d like to try a glass baby bottle, here are the best ones on the market today:

Curved so they're easy for you (or your baby) to hold, the Philips Avent comes with a naturally shaped teat that mimics a nipple to give your baby the best chance of latching on easily. Available in 120ml, 125ml, 240ml, 260ml and 330ml.
