Re: Nipple Nipping
First of all, ouch! I am so sorry you're getting chomped. That stinks.
You are correct that this sort of thing can turn into bottle dependency or nursing strike. So despite the fact that you're getting chomped, it's important to try to keep nursing.
First thing to do is to try to identify when baby bites. Does it happen at the beginning of a feeding, or only when the feeding is mostly over? Sometimes if you know when a bite is likely to come, you can head it off at the pass by adjusting the baby's position or taking him off the breast (if bites come when he's done nursing for food and is only sucking for comport).
Second thing to do is to calmly and consistently condition your baby not to bite. When a bite occurs, take him off the breast, tell him "No bite, hurts mama," and then put him down and walk away for a while. Don't simply give him a bottle of pumped milk, because that just teaches baby that no matter how bitey he is, he'll still get his needs met. In theory, this all teaches baby that biting has the immediate effect of ending the feeding and the fun cuddle time with mama. It may take many repetitions for this lesson to take hold, so just keep at it!
