We have a child who in persistently biting the other children. We have tried distraction and obviously intervening when we see a situation arising, and lately we have even been shadowing this child. The trouble is, when he is removed from the area and sat away, he just laughs at us. Any conversation about how sad he makes us and the other children is seemingly not registering. any suggestions please. He is only 2, but just doesn't seem to understand that his actions are wrong. I do appreciate that he is young, but just doesn't seem to care when he is removed from playing.
