Heating Human Milk in the Microwave
Can human milk be heated in the microwave?
"Do not heat... milk in a stove or a microwave oven" states LLLI's THE WOMANLY ART OF BREASTFEEDING, 7th Revised Edition, 2004 on page 122. Warming your stored milk in the microwave causes it to heat unevenly, creating "hot spots" that may burn your baby's mouth. Furthermore, valuable immunological components can be destroyed if the milk gets too hot (p. 158).
Frozen or refrigerated human milk is best heated by holding the container of milk under cool running water and gradually adding warmer water until the milk is thawed and warmed to room temperature. If running water is not available, a pan of water can be heated on the stove. The container of milk can be placed in the warm water once it has been removed from the heat source. Milk can also be defrosted in the refrigerator overnight.
