My daughter is 3 months old (today) I need to return to work within the next few weeks. I am wondering, how do I continue to feed her and still pump enough to freeze? I find I can pump 5 oz first thing in the a.m. from one side (leaving the other for her to have when she wakes up). During the rest of the day I can't seem to get more than 1 to 2 oz at a time from the opposite side of where she's eating. Am I supposed to pump more frequently? Pump from both sides?? Help!!
