So I'm nursing full time and pump when I'm at work three days a week. I use to be able to pump 4-8 ounces both breast no problem and now I can hardly get three ounces. I'm getting worried cause I don't think eight ounces is enough for my ten hour shift tmrw. I'm pumping now but not a lot what can I do? #breastfeeding
