My son recently turned 6 and started 1st grade. He has trouble focussing in class and often gets into trouble because of that. He has also started to act funny and getting into more trouble recently and nothing seems to motivate. He behaves differently at home. He is playful. I am trying to work with in understanding right behavior at school and any public setting. I am not sure what else I can do to motivate him and help him from going into wrong direction?
