Re: pumping question..
My pediatrician wanted me to pump after each nursing session to make sure I got out all the hind milk and to stimulate my supply a few months ago. She told me I probably would only get about 1oz after nursing so it sounds like you are doing fine in what you are pumping out. I also use a PIS advance and I find it can really hurt if I have the suction up too high like a PP said. And Medela does make different diameter breast shields so you may want to look into those like a PP suggested.
