My baby is 13 weeks old and has been BF with some formula top ups. We have gone through times where he requires v little formula and others where he has needed more. At its highest I would say formula accounted for 1/3 of his intake. Anyway, over the last few days he will bf for between 5 or so minutes and then keep pushing the breast away and cry. He is still hungry as when I switch him to the other side he will feed again, then the same thing happens and I then offer a bottle (ebm or formula). It seems that whenever the flow slows he gets frustrated. I am sure there is still milk there when he gives up. I am expressing (still getting as much as ever)and he is happy to have ebm in a bottle, so it isn't the milk. Please help as I have worked so hard to get where I am with bfing as we had a very difficult start, and I don't want my baby to reject my breasts as he seems to be gravitating towards at the moment.
