I've started expressing my BM, but I'm only getting 4oz if I'm lucky. I've been expressing about every 2 hours. I've started do that because my little one seemed like she never got enough off the breast. My main concern is her diapers have started turning a little green. We haven't had another doctor's appointment yet, she will be 4 weeks on Wed. Her appointment isn't til next week. So she drinks the whole bottle that I had just pumped...starting to get a little discouraged. I'd really like to breast feed, but not sure what to do??? Please help!
