Breastmilk Storage Guidelines

*Do not mix freshly pumped milk that is still warm with milk that has already cooled.   If you would like to mix numerous pumping sessions and store in one bag, cool the warm milk before mixing.

* If you wish to add freshly pumped milk to an already frozen bag, make sure the freshly pumped milk is chilled and is less in quantity than the already frozen portion.
*Milk should always be stored in specially designed bags for breastmilk.  Look for BPA free bags.

*To avoid wasting milk, freeze in portions of 2-5 ounces.

* Be sure to date each bag, using the oldest stored first.  Make sure bags are sealed tightly.
*If you notice a soapy taste or odor after freezing, this is due to a naturally occurring enzyme.  To avoid this, put bags in a pan of water and bring to a scald.  DO NOT BOIL.  Heat until tiny bubbles rise along the sides of the pan.
*Immediately freeze breastmilk you do not plan on using within a few days. Place in the coldest part of the freezer and avoid putting bags up against the freezer wall.

Milk can be stored in a refrigerator for 3-8 days and in the freezer for 6-12 months.  Thawed breastmilk should be used within 24 hours, and breastmilk should not be left at room temperature for more than 4-6 hours.
