My baby girl as suddenly taken a disliking to my left breast. She will scream to be fed, or suck on her clothes, then when I pick her up to feed she won't take that breast no matter how hard I try. I end up putting her on the right because she screams at me. She takes the right breast with no problems, but then she will get full and only take the left for a tiny feed, or not at all. What can I do?
