My 9 week old baby cries constantly and always appears unhappy. Recently he has stopped breast feeding so I have had to put him on a bottle - things have got worse. He only likes to be upright, struggles through feeds, getting upset, I have trouble burping him and prefers sleeping with head raised. I wonder if it could be reflux and if there's anything I can get over the counter to help. I don't think I can cope with the crying for much longer.
