My 10-month-old daughter started biting her breast hard while playing with it, squeezing it with her fists when she eats. I have one nipple swollen up so much that it hurts to touch, not even talking about feeding! When she bites, I raise my voice, take the breast away, and tell her "No", it hurts me. But it's useless. After 10 minutes, she asks for the breast again and bites again.
