Formula Feeding

Sterilising bottles and equipment

It's vital to sterilise bottles, teats and other feeding equipment properly because any bacteria not thoroughly washed away can give your baby an upset stomach. Here's how to keep your baby safe.

In Short

There are four main ways to sterilise feeding equipment, and you do this after you've washed everything thoroughly in hot soapy water, using special tiny brushes to get into every nook and cranny, then rinsed it clean.

Cold water sterilising solutions

Boiling in water

Microwaving

Steam steriliser

ALWAYS WASH BOTTLES AND EQUIPMENT IN HOT, SOAPY WATER, THEN RINSE THOROUGHLY BEFORE STERILISING

Use a special small bottle brush to get into all the nooks and crannies.

Then sterilise using your chosen method as follows:

Cold water sterilising solution

  • Usually, there are tablets to be dissolved in water.
  • Follow instructions on packet precisely.
  • Leave everything completely submerged in the solution for at least 30 minutes.
  • If you push anything under, the pushing needs to be done with something sterile.
  • Once sterile, rinse in water that has been boiled, or use straight from the solution.
  • Change the solution at least every 24 hours.

Boiling in water

  • Completely submerge bottles and equipment in water in a big pan.
  • Bring to boil and boil for 10 minutes.
  • Keep submerged throughout.
Microwaving
  • Some bottles (read the instructions when you buy them) can be sterilised by putting in a microwave for 90 seconds.
  • Put them in without teats or lids on and sterilise these separately.
Steam sterilising
  • There are many different brands, so it’s a case of which unit suits you, your baby’s needs – and your kitchen space!
  • You must read the instructions and follow precisely.
  • They usually take around 8-12 minutes.
  • Usually, you can leave them in the closed steriliser for up to six hours after running the cycle.
