Tips for Freezing Breast MilkUpdated 7 days ago

If using BPA free plastic or glass bottles to freeze milk, leave the tops of the container loose. Tighten once completely frozen.

When freezing breast milk, leave an inch of space in the container, as milk will expand when frozen.

Store milk in the back of the freezer, away from the door, to assure a steady temperature.

Do not combine frozen and unfrozen breast milk. This can cause bacteria to grow.
