I have a 9yo son with adhd and has recently tried numerous RX but nothing seems to help him. He has calmed down in behavior, but is now getting bad notes home because if his inattentive behavior. He doesn’t understand the teacher’s lessons but doesn’t know how to ask questions. He is currently on a 405 plan but I don’t think that’s working. I’m at my wits end with his teacher and him!! Help me!!!
