He is still eating like crazy but now I think it has become a comforting thing for him. When he starts screaming after he's been nursing for 45mins I will put him back on and he will fall asleep in 5 mins. Or he will suck for over 1 hour and then spit up half of it. I'm afraid he will get a belly ache from over eating! We are still working on using the pacifier but I'm sure that's just contributing to his nipple confusion! I just can't win but I've stopped trying too hard and I'm just letting things happen as they happen. I'm still using the nipple shield but it is not hurting as bad as it had been.
