My two-year old son is so sweet most of the time and is so smart. He makes us so proud. However, he has learned some bad behavior from his older cousin and I am struggling to deal with it. I have caught his cousin hitting, pushing and yelling at my son if he made him mad while they were playing. Unfortunately, my son looks up to his cousin and has picked up on that behavior. He has begun to hit and push his younger cousin, who is much smaller than him, and the older cousin. It appears that he is doing it to get a reaction and not to hurt them. He will also occasionally slap me or my husband on the arm or even in the face and then laugh. We sternly correct him, and also put him in time-out , each and every time he does it, to us or other kids, but he continues. Does anyone have any advice on how to stop this behavior?
