Help! How can I produce more milk?

Jenn

My daughter is two weeks old and I've decided to pump and supplement with formula if needed. But my daughter is still in the hospital (for personal reasons I can't mention) and really needs my breast milk to help her get better and come home. My supply has dropped down. If I pump every 3 hours I only get like 1oz. If I wait several hours then I might get lucky and pump 2oz. I'm kinda new at this since I never did good breast feeding my other kids. I really want this to work out. So please anyone have any good suggestions and what is power pumping exactly? Thanks!
