Is there anything I can do? I can't even say stop or no to him as he's doing it in his sleep! I was dosing this morning whilst feeding him (5am ish) and when he's done he seems to just clamp down. It really hurt and I even said ouch!
It isn't just a quick nip either he really clamps down and it takes a good few seconds to get my nipple out of his mouth. It's very sore now when he feeds.
Its making me apprehensive about feeding him to be honest. He never does it anymore while he's awake, only sleeping. I've tried detatching him towards the end of the feed when he's sucking more for comfort but he wakes up and screams and goes red and rigid until I let him feed again.
