Once prepared, formula should be consumed within two hours or stored in the refrigerator and used within 24 hours. Breast milk can be stored in a refrigerator for up to 4 days, in a freezer for 6 months, and in a deep freezer for up to 12 months. Always label the containers with the date the milk was expressed.
