Help, Baby won't feed from my right boob, its getting massive and I'm going to have to express soon of she doesn't take any. She is 4 months old and currently screaming her head off with her daddy, she hasn't been feeding well at all today/ I have a bad cold and have been taking beechams and we both had thrush for a while but I think we've got rid of it. Also she used to have colic, thats seems to have cleared though tonight it looks like it is back! Any other reason why she won't feed from my right boob?
