I have 2 boys aged 7yrs and 4yrs. My 7 yr old son is displaying concerning behaviour. He either plays very cooperatively with his younger brother or is very physical with him. He is extremely short tempered with him and will punch, kick or push him. I have tried all kinds of consequeces with him. We are a household that does nt smack our children and i am worried as nothing seems to make a difference to the behaviour. I have taken toys away, used time out, stopped plays with friends, taken pocket money away and reward charts. At school, my son can easily complete the work but chooses to socialise with everyone and not complete the written tasks set out for him. He chooses to also interact with the older chidlren at school rather than his own age. Friends often comment that my son is way older than their children in the some of the things he does. Any suggestions would be fantastic.
