frozen milk...

how do you thaw it out and how soon do you have to use it after thawing it?

[@llli*auderey]

thaw in the refrigerator, and all guidelines say to use within 24 hours. in practice in my family we could stretch that a little bit, but it never re-heated (for a 2nd feed) without spoiling. it'll be obvious when it's spoiled.

I thaw under running warm to hot water. I prefer to thaw in the fridge, but I forget

you can also use cool water - that way you won't kill any of the goodness. thaw in refrigerator is the best.
