Using Frozen Breast milk

iStock_000069907977_XXXLargeNever thaw frozen breast milk in the microwave.

Thaw frozen breast milk:

  • In the refrigerator
  • Hold the container under cool water and gradually increase the temperature of the water. Shake gently to circulate temperature through the milk.
  • The milk container can also be placed in a bowl of warm water.

Fats may separate during storage, but milk is still safe. Gently shake to combine fats with milk.


Breast milk storage DO’S AND DON’TS

(via the Mayo Clinic)

For storing milk:
DO use a capped glass or BPA free hard plastic container or plastic bag designed to hold breastmilk.

DON’T store milk in a plastic bag used for other household purposes.

DO store in amount that normally is used in one feeding and in smaller amounts for special purposes (for example 1 to 2 ounces or 2 to 4 ounce amounts).

DON’T fill to the brim, as milk expands as it freezes

You can add freshly expressed milk to already stored fresh or frozen breast milk as long as the milk is cooled prior to mixing it with previously expressed milk.

Avoid adding warm expressed milk to previously frozen breastmilk.

ALWAYS WASH HANDS BEFORE EXPRESSING, STORING AND THAWING BREAST MILK
