I have a 6 year old son with ADD/ADHD who just started kindergarten. We have been working on the alphabet for as far back as I can remember. He can recite the letters just fine but when asked to identify any of them out of order he can't do it. We have tried flashcards, we have tried textile learning where he traces the raised letters as he says them, we have tries learning 3 letters a week and writing them repeatedly for 5 days at a time. Nothing is working for us. He is currently not on any prescription medicine. We give him Calm Child drops that seem to really help him with sitting still in class. We do not want him to fall behind! Please help!
