Milk Storage Guidelines (2018).
Date all breastmilk and use the oldest breastmilk first.
NOTE: DO NOT refreeze milk once it is thawed.
Thawing
Thaw frozen milk in the refrigerator or place the containers under cool running water,
gradually warming the water until the milk is thawed. Thawed milk can be kept in a
refrigerator for up to 24 hours.
Breastmilk is not homogenized and you may notice that it separates as it sits. Gently swirl
thawed milk before feeding to baby to mix the layers that have separated. Breastmilk
can vary in color and consistency depending upon the time of the day that the milk was
expressed, what you have eaten, and the age of the baby at the time of pumping.
Please check local guidelines for the most current breastmilk storage and usage

et du travail. Recommandations Françaises. Guide Lait Bébé 2007.
NOTE: DO NOT MICROWAVE HUMAN MILK! Microwaving alters the composition
of the milk. Microwaving also may create "hot spots" in the milk that could burn
the infant
NOTE: DO NOT thaw breastmilk in hot or boiling water.

THINGS TO KNOW
Containers should be covered and kept as cool
as possible. Covering the container with a clean
cool towel may keep milk cooler. Throw out any
leftover milk within 2 hours after the baby is
finished feeding.
Store milk in the back of the refrigerator. When
at work, it's OK to put breastmilk in a shared
refrigerator. Be sure to label the container clearly.
Store milk toward the back of the freezer where
the temperature is most constant. Milk stored
at 0°F or colder is safe for longer durations, but
the quality of the milk might not be as high.
