What happens if you use thawed breast milk after 24 hours?
Then, why is breast milk good for 24 hours after thawing?
Microwaving can destroy nutrients in breast milk and create hot spots, which can burn a baby's mouth. Use breast milk within 24 hours of thawing in the refrigerator (this means from the time it is no longer frozen or completely thawed, not from the time when you took it out of the freezer).
Consequently, how long after breast milk is thawed is it good for?
Once fully thawed, previously frozen breast milk may be kept at room temperature for a maximum of two hours or in the refrigerator for up to 24 hours.
Milk from different pumping sessions/days may be combined in one container – use the date of the first milk expressed. Avoid adding warm milk to a container of previously refrigerated or frozen milk – cool the new milk before combining. Breastmilk is not spoiled unless it smells really bad or tastes sour.
