My almost 4 month old is refusing to nurse on the left side. I have had to do some hand expressing, just to get rid of some of engorgement. When I hand express from the left side, which is the side he refuses, there are like 7 to 10 streams of milk that come out. On the right side, I only have 4 to 5 streams of milk. Could it be that the milk is coming out too fast for him to nurse comfortably? I've tried all different positions, but he still cries when I put him to my left breast. Is there anything I can do?
