How Quickly Should Thawed Breast Milk Be Consumed?

Frozen breast milk comes in handy when you're not able to nurse your baby. But once you thaw it to room temperature, it should be used within four hours, recommends certified lactation consultant Shirley Donato, of Virtua Memorial Hospital in New Jersey. If you won't use it in this time frame, it should be refrigerated. Frozen milk loses some of its antibacterial properties, so it doesn't last as long as freshly expressed milk.
