DS 13 months, will not stop biting me (hands, face, neck!) and anyone else he can get his teeth into! It's really quite hard, he's drawn blood several times. Have tried saying "no" very firmly, he either laughs or cries (depending how firmly I say it!) but either way just carries on. Have tried saying "it hurts mummy" and pretending to cry to try and show him it makes other people "upset", but think he's just too young to understand that message! Give him calpol and bongela if I think he seems particularly bad with teething, and have tried teething rings etc (which he's just not interested in) but he is always biting, it can't always be teething! Worried in particular he will really hurt one of the other LOs in our toddler group! What should I do?
