Hello, this is my third child and I breastfed the other two for 15 months each! My newest is 7 weeks and I thought we had a great nursing routine down. Until tonight. It was as though my left breast totally deflated! He still seems to be nursing from that side, but it is not full like the right breast! I am concerned my left breast is no longer making milk? I have not felt it "fill" up since 7pm and it is now 1am and my right breast has filled up. I did just feed him, but it is still uneven? Help!
