Q: How do I safely store and serve breastmilk to ensure freshness?

A: The easiest way is to follow these four simple guidelines: 

  1. Breastmilk can be left out at room temperature for 4 hours.
  2. It is safe to store for 4 days in the refrigerator.
  3. Breastmilk is ok for 6-12 months in the freezer. The colder the temperature and less exposure to various temps the better, so a deep freezer or the back of your freezer is better than the door of a standard freezer.  
  4. Thawed or previously frozen milk can be left at room temperature for up to 2 hours and in the refrigerator for 24 hours. Never refreeze breastmilk after it has thawed!
