My daughter is 13 months. Her top teeth are about half way in. While she nurses, her top teeth cut into my nipples, at first causing indentation and now small cuts. Nursing right now is so painful I don't know what to do. I read that babies can't bite when the suck, but she doesn't seem to be biting me, but scraping I guess. I am not interested in weaning, but it is really painful. Please help.
