My daughter is a month old and we have been bf. In the morning she eats and afterwards I have 2.5-3 ozs I pump out.

After that the rest of the day i don't use the pump unless shes getting a bottle. When I have to give her a bottle I can only get 2 oz. Is that an ok amount for a 4 week old baby? Most of the time she seems full after eating but everyone in a while she still seems a little hungry..
