I need help! My 11 month old is really starting to bite hard. As far as I can tell he isn't teething. He is not only biting my nipples, today he bit my arm really hard! When I try to nurse, he will twist and wiggle in my arms instead of just laying in the craddle hold like he used to. Now he will lay on his tummy, with one leg on either side of my knees He will move his head from side to side. I can't get him to sit still. Any suggestions on either the bitting or the moving while nursing would be greatly appreciated. I have dealt with his bitting while he is teething before and this seems to be somewhat different. I am at a loss and I am afraid I will be nippleless soon!!! Help!!!!!
