I have a 12 year old boy who speaks very disrespectful to my husband and I. In addition, he has always been strong willed. He started speaking disrespectful about 6 months ago and it seems to be getting progressively worse. He does very well in school and is very self motivated. He speaks polite to teachers and other elders. He for the most part is only disrespectful to us. He is the oldest of three boys and likes to boss around his brothers as well. I have tried to give him some consequences (like an extra chore to do), and the disrespectful attitude stops for the rest of the day, but then usually starts up again soon thereafter. In addition, there are not many privileges I can take away from him. We already significantly limit television time to weekends ( about 1-2 hours on saturday and sunday), and he does not own any computer equipment other than his laptop for school. Do you have any suggestions how to stop his disrespectful manner?
