DS is 7 weeks old now and is EBF. Up until a week ago BF had settled down and both me and DS had got the hang of it. Now he seems to suck on the nipple which makes it painful, comes on and off making feeding last a long time and also seems to throw up much more than before.
I have tried a bottle (TT closer to nature) with expressed on a couple of occasions, as I had to be out for a morning - could this be the problem?
