Hi Chemar, Thank you for the welcome and the link. I checked it out but don't think it's the problem. My son was very active before he was even born, I could feel him move around so much, people could even see it from across the room. He is also very clever, he taught himself to read at 4 and does math for fun, he has touch typed from 5 years old, again he taught himself. So there is no regression. He has fears that stop him using a toilet, in every other way he is so much older than 9 years old.
