how to use breast milk stored in fridge...once baby drank from the bottle and leftover milk can it be again given to baby within how many hours it should be completed at room temperature please provide guidance

A. Leftover milk cannot be given again you have to discard it and if your child is not accepting it with bottle then either you can use a spoon to feed your child and in some cases the child is pretty much sure you can also use a syringe to feed the child
