Quoting Chim Richalds:" If she is biting, she isn't actively nursing. You might just have to watch her and judge for yourself when she isn't getting milk anymore and proactively end the session before she bites."that is what I was thinking...that is why if she does it more than once I end the session. it hurts so bad...she will like bite me and then pull he head back and my nipple goes with it!!!
