How come I can't pump? I have a Madela borrowed from WIC. I thought it was bc baby was emptying me so that's why when I pumped after I would get nothing. But here I am full pumping n nothing is coming out. Why? I thought I could pump n then go to library for kids class so I wouldn't have yo breastfeed there as last time I got dirty looks n it made me uncomfortable. But that's not the issue. The issue is how come I can't pump my milk. I go back to work in 5-6 weeks n need to eventually build up a supply. I can't do that if I can't pump. Please help.
