I love my son dearly but it both breaks my heart, and makes me furious when he is spiteful to other children. He is a very loving child and can be the most delightful, pleasant and well mannered child ever. But around other children he turns into a spiteful child who smacks, punches and kicks other children. I have tried to encourage nice playing but it doesn't seem to work. He doesn't seem to have any proper friends and the ones he does have all smack, kick and punch like he does which doesn't help us (me & dad) to encourage nice playing. I want to teach him to play nicely but am failing miserably. Any advice welcome
