My baby is 5 1/2 weeks now and for the last week or two I've been having problems with feeding him. I think I've sussed what kind of cry means that he is hungry initially and he seems to latch on ok. He will then often feed for between 5 and 10 minutes continuously and then slow down taking a few sucks now and then. When he comes off this is where the trouble begins. I try to sit him up to burp him and he often starts crying and resisting me by pushing backwards. The only way I can settle him a little is up on my shoulder but he will eventually start crying again. I will then try him with more food. He then has a period of half sucking and feeding then coming off and crying often being a little sick. I usually manage to get him to burp a few times but he never seems satisfied and happy. Any tips or ideas?
