Storing Breast Milk After Expressing

To store expressed breast milk, use containers or bags that are specifically designed for this purpose. Ensure the materials used to make the containers are either glass or plastic and have lids that fit securely. Do not use bottles with the number 7 recycle symbol, as these may contain BPA. Also, never put breast milk in disposable bottle liners or plastic bags that were not meant to store it.

You should freeze freshly expressed milk within four days to keep it as fresh as possible. However, do not refreeze breast milk once it is thawed.

To avoid wasting milk that might not be consumed, store fresh milk in 2 to 4 ounces or the amount of milk given per feeding. Be sure to leave an inch of air space on the top of the container because breast milk expands when frozen.
