My ds has recently started biting me, just me. Not in temper but while we are playing or cuddling. It really hurts.This morning he drew blood! My mum suggested i should say no sharply and smack him on the hand. I personally don't think this is the best way to deal with it. He starts nursery next month and i would hate him to bite other babies, so i want to nip this in the bud. Does anyone have and advice of how to deal with this?
