When re-refrigerating ebm, is it okay to put it back in the refrigerator while it is still in the bottle? Or should I re-bag it? I was told by a friend that if the bottle is not used within an hour, it has to be tossed because of bacteria on the nipple and backwash. I guess this makes sense, but I was wondering what other people were doing about this. As I am attempting to get ds to take a bottle, I feel like I am wasting a lot of milk, even though I only measure out one ounce at a time.
