We have been issues with our daughter. She is great at school but at home she is flat out defiant. We have tried everything and nothing has worked so far. My grandma is staying with us for a few months and even she is at a loss at what to do. We were all talking last night about putting her in Karate. Has anyone one had issues with thier child being defiant and tried Karate? Did it help? She is almost 7 by the way.
