Question: how many ounces of breast milk to freeze?
Answer: How much of my milk should I store in the freezer? Although some women may choose to pump large volumes to be frozen, it's a good idea to actually store the breast milk in 2- to 4-ounce (59.1 to 118.2 milliliters) portions so as not to waste any. Label the bottles, cups, or bags with the date, then freeze them.
