Storing and Defrosting Breastmilk:
The easiest way to remember storage duration for breastmilk is to remember 6 for everything:

-At room temperature for up to 6 hours.

-In the fridge for up to 6 days.

-In the freezer attached to the fridge up to 6 weeks (possibly longer if placed in the very back, not in the door).

-In a deep chest freezer for up to 6 -12 months.

The ideal way to defrost frozen milk is to place it in the fridge overnight to allow it to defrost slowly. If you need the milk in a pinch here a few helpful tips:

-Never use a microwave. It can destroy the beneficial milk properties and antibodies. It also will heat the milk unevenly, leading to hot spots that can scald baby’s mouth.

-Simply place the breastmilk storage container in a cup of warm water, close to body temperature to preserve all of the milk’s amazing properties. Changing out the water a few times will help to defrost the milk faster.

-You can also try placing the bottle under warm running water for a few minutes.

-Always check the temperature on the inside of your arm before giving warmed milk to baby.

  1. This is great! Thanks! I’m currently pumping and storing LOTS of breastmilk for a friend’s adopted baby and I’m looking for other options besides the Lansinoh bags. This has given me a couple of ideas…. 😉
