How should you store your breast milk?

Breast milk can be stored in a clean glass or hard BPA-free plastic bottles with tight-fitting lids. Or you can use sterile, sealable, milk storage bags (don’t use disposable bottle liners or other plastic bags to store breast milk). If your baby eats 4 ounces in a feeding, put 4 ounces of breast milk in the storage container and put a date on the container so you know how long it will last. Storing it in premeasured amounts will help avoid any waste of breast milk.
