My DS is 8 months old and we have been BF really well up until now (with a few issues of distraction, nipping etc, but that's normal). But yesterday he totally refused to feed all day. If I put my nipple near his mouth, he would scream and turn away, and twice he chomped down so hard that he drew blood on the top and bottom of my nipple. He has two teeth on top and bottom Ouch. So, 2 problems. My BBs were so engorged and rock hard, and I expressed. But my lefty remains incredibly sensitive and sore. It's not lumpy like maybe mastitis, but its just really really tender and hurts to touch it or move. Could this be from being over engorged, or from expressing maybe on too high a setting? Do I put hot wheat bag on it, or something cold?

And secondly, I am now scared to feed him (especially on that side) for fear he will bite again, and it just plain hurts enough already. He fed on it during the night when he was sleepy and that was OK, he didn't bite, but it hurt.

I am totally committed to BF for as long as possible, I know this is a little hurdle, but what to do?
