How to safely store breastmilk

If you’re expressing, knowing how to safely store your breastmilk can be a little overwhelming. So here’s everything you need to know.

You can store your breast milk in sterilised containers or special bags. Just remember to date all your milk and keep in small quantities so you don’t waste anything.

Freshly expressed milk should be stored:

  • At room temperature for no more than six hours.
  • In the fridge for no more than eight days if your fridge is 4C or lower, three days if not.
  • In the freezer for up to six months if it is -18C or lower.

Previously frozen milk that’s been thawed in the fridge should be stored:

  • At room temperature for no more than four hours.
  • In the fridge for no more than 24 hours.
  • Not to be refrozen.

Previously frozen milk that’s been thawed out of the fridge should be stored:

  • At room temperature for up to an hour.
  • In the fridge for no more than four hours.
  • Not to be refrozen.

Remember not to use a microwave to heat up or defrost breast milk. To warm up your milk, put the bottle in warm water or hold it under a hot tap.
