We know that for new parents, sterilising can sound intimidating at first...

…like you should have a lab coat and some goggles to get your baby’s bottles clean! 

But don’t worry, it's not as scary as it sounds.

A key step in your baby’s feeding routine

It's important to sterilise all your baby's feeding kit, including bottles and teats, until they’re at least 12 months old.

During their first year, your baby’s immune system isn’t yet fully developed, meaning they’re more susceptible to illnesses than older babies and toddlers.

Sterilising their feeding equipment goes beyond keeping things clean – it’s about getting rid of any leftover milk residue that might be lingering and protecting them from harmful bacteria and mould that can cause tummy bugs and illnesses like diarrhoea and vomiting.

Getting started

It’s recommended that you sterilise anything that touches breast milk or formula, as well as anything that regularly goes in your baby’s mouth.

This includes their bottles and teats, but also things like breast pumps, soothers, toys and teethers!

We know, it seems like a lot of work, but it really doesn’t take too long and it’s super simple – it’ll become a natural part of your daily routine in no time!

When Can You Stop Sterilising Baby Bottles?

Sterilising a baby’s feeding kit is crucial, but as they grow, their immune system gets stronger, and eventually, you'll no longer need to sterilise their feeding equipment.
