My 8 week old baby has recently started fussing during nursing. He will squirm and sometimes vocalize. Originally I thought he was in pain (he does have reflux). However, he never cries. I also thought perhaps I have overactive letdown. However, he doesn't pull of coughing, choking, sputtering, etc. In fact, he usually doesn't squirm during letdown. Could he be frustrated that the flow is too slow? Yesterday morning he was so fussy I just switched to a bottle - he didn't move a muscle. I have tried nursing in similar positions (so that he is in the same position as when he takes a bottle) without success.
Any thoughts and/or advice? Oh, I did have an oversupply/overactive letdown early on. Perhaps he got used to it?
