DS has started biting me (and only me ). I have 2 hickey-like marks on my shoulder which are quite sore. There isn't one reason that I can see - if he gets excited he bites or if I'm cuddling him but not paying attention, if I'm trying to get him to do something etc.

I yell (ouch involuntarily), then tell him it makes Mummy sad when he bites, and today have been taking a car off him each time. I've tried to put his arm in his mouth so he doesn't bite me and sees how it feels, I've tried asking him why, but not gotten an answer - asked if its because he wants me to play, he just laughs.

DH says maybe its 'cause of bf that he bites me, but I can't see why it would be.

What do I do to stop this? I'm going to make an effort to be more attentive (which should help with TT if nothing else), but what else should I do?
