If I heat expressed breast milk that was stored in the refrigerator for a few hours in a bottle using a bottle warmer how long do I have to feed it? For example, I just nursed my 1 month old and she started acting hungry 20 minutes later so I heated some milk that I pumped a few hours ago. She took one suckle and fell asleep and refused to eat anymore (bottle or breast). She just wants to sleep.
Do I need to dump the milk or can I keep it for a little bit to see if she wants it again? If I can keep it, how long and should I keep it at room temp or put it back in the refrigerator?
