Re: how much should come out
I don't have experience with preemies, but getting 1-2 oz per pump is totally normal. Susan might chime in on establishing a supply through ep - I think I've heard her say you need to pump every two hours around the clock for several weeks. Congrats, and awesome job on the pumping!
DS 6/7/11 - Still night & morning nursing, but the rest of the time he just doesn't have time for me! After mostly working at home, gleefully packed away the pump at 11 months.
Another on the way in October 2013!
