My DD is 9months old and has 6 teeth. She is breastfed and has started biting me if she doesn't want to feed or if she's finished drinking. It's really only been over the past week since she's got the top 4 teeth (that's right 4 teeth in 4 days!!). I try taking her off the breast and saying 'no!' but she just laughs at me. Any ideas? I don't want to stop BFing her
