I have been nursing twins for 14 mos. Recently, the one with both upper and lower teeth is just tearing up my nipple when she nurses. She isn't clamping down or really biting. It's just like her teeth are rasping my nipple in rhythm with her sucking. I am tandem nursing so I don't really want to pull her off and disturb her sister. Once interrupted they sometimes don't want to finish feeding.
Is there some way to get her to nurse without using her teeth? Different position maybe?
