Have you read the book"transforming difficult child-nurtured heart approach"? I am using it with my seven year old son, who has been wearing me out every day.

It works to some degree,but he could not give up pushing limits. Just earlier tonight, he ignored me and kept making noises after lights were out and made his brother doing the same. I feel furious and I could not effectively control my emotion and yelled at them despite the advices in the book about not to respond with negative emotion. This is so hard! I don't know what to do with this child any more.

So I understand those of you who has difficult child. We did everything we could.
