I actually did talk to parents about how the child thinks everything is a game, before the biting happened. I suggested being firm when he hits and not letting him see it as a game. I saw this kind of thing coming. He had started trying to hit me occassionally when he was annoyed with me etc. He is a very sweet, kind little guy and despite all this I would not call him aggressive. But I think he just thinks it's all a game...anything goes. The problem with explaining to him that it hurts his friend etc, is that he is totally non-verbal and doesn't actually understand when I say things like that (well at least he does not show any comprehension). It would be very hard for me to get him to hug or kiss instead...he just doesn't understand what I am getting at. The parents seem to think he has learned hitting and biting somewhere (well insinuating here from the other kids), but I am trying to get them to understand that it is an impulse and a normal phase toddlers go through that we need to help them get out of quickly.
