Hi I am a parent of a 6 year old boy, the last few months he has been behaving very badly, especially since the schools hols started. He will not do as he is told, he becomes defiant, aggresive and it usually ends in tantrums, we are having difficulty parenting him. It is causing our family great upset, he laughs went he is getting a row, tells lies and is very controlling to his friends. We have looked at his diet , we just dont know where to go from here?? He has excellent behaviour when at school
