Proper storage of breastmilk ensures your baby gets safe, nutritious milk. These guidelines follow CDC and Academy of Breastfeeding Medicine recommendations.

Key Storage Tips

  • Always label containers with the date and time of expression
  • Store milk in the back of the fridge or freezer, not the door
  • Use BPA-free containers or breastmilk storage bags
  • Leave room in containers for expansion when freezing
  • Store in small amounts (2-4 oz) to minimize waste

Thawing Guidelines

  • Thaw overnight in the refrigerator (safest method)
  • Thaw under warm running water or in a warm water bath
  • Never microwave breastmilk
  • Use thawed milk within 24 hours
  • Never refreeze thawed breastmilk
