That's the only way I can describe it, he will feed for a few minutes, then wriggle and wave is arms and come off. If I put my breast away he'll start rooting for it again. He will often mouth my nipple and make a half-arsed attempt to feed. He doesn't appear at all distressed during. Does this seem normal? He's gaining good weight and I feel that bf is going well apart from this relatively new behaviour. At other times he latches on and is there for 20-30 minutes and not move a muscle.
