Reusing warmed Breast Milk?

lukesbtb

So if I defrost frozen breastmilk and warm it OR if I warm breast milk from the fridge, can you reuse the leftovers? Say I had 4 ounces in the fridge, warmed all of that but DD only took 2 ounces.. do I have to dump the rest cause it has been warmed or can I put it back in fridge and reheat later????

You have to use it within I think 4 hours?  You cant put it back in the fridge but it can sit at room temp for a while.

kellymom says you can use it at the next feeding, but anything left at that point would need to be discarded.

ETA:  I would leave it at room temp and not put it back in the fridge (to avoid reheating), but I smell it before offering it to DD. It should still smell sweetish, not sour or musty. I have done this many times and been fine.
