Why is it my nearly seven year old boy hurts his school friends(boys and girls) for no reason? He is loving and caring most of the time at home and sometimes I think he does not understand that what he does can hurt. He has two older siblings and is a very tall boy for his age- its no excuse! But I have tried everything from getting angry to telling him how disappointed I am, hes sorry and remorseful but then a week later he seems to forget and the whole issue starts again! How do I hammer it home???
