Preserving the quality of stored breastmilk is an important part of keeping your baby healthy. Breastmilk can spoil when not kept properly, which is why proper storage is vital. The following guidelines can help you make sure that you’re on the right track and doing what you need to do to keep your breastmilk safe for your baby.

  • Make sure to wash your hands with soap before expressing breastmilk. Also, make sure that your hands are clean when handling sterilized bags or bottles. This will minimize the bacteria that might contaminate the breastmilk.
  • Label your breastmilk storage bags or bottles. Use a waterproof marker to put the name of your baby and the date you expressed the milk stored in the container. This will help you keep track of which containers hold older milk.
  • Don’t add freshly expressed breastmilk to frozen or refrigerated milk while it’s still warm. Put the still-warm milk in the refrigerator and let it cool down. Once it’s cool enough, you can add it to the older milk.
  • Don’t refreeze thawed milk. Once the milk has been thawed, you have up to 2 hours to use it all up. Refreezing thawed milk increases the risk of bacterial contamination, which can end up in your milk spoiling.
  • Take note of how long breastmilk will last in specific situations. You can leave freshly expressed milk at room temperature for up to 4 hours before it starts to spoil. If you put it in the refrigerator, it can last for up to 4 days. If you freeze it, it can last for 6 to 12 months. You can also leave thawed milk in the refrigerator for up to a day.
  • Make sure that you thaw older breastmilk first. This is why labeling with dates is important. While frozen breastmilk can keep for months, its quality can degrade the longer it’s kept stored.
