TwinkleToes, my DS8 is still waiting for more tests from psycho evaluation. He has many behaviors fitted OE, ADHD, AS, SPD symptoms. I searched information online and read books and still cannot figure out what he has. Then I decided to seek professional help. When I filled out the forms that doctor gave me, I ruled out AS. I still concern about ADHD though. When I read the forms, there are so many behaviors on the list fitted my son few years ago. Now he just outgrew them. I think if I have him evaluated few years ago, I would get different diagnoses. I can relate your feeling but 4 is still young. If there is no emergency issue, I will suggest to wait for one or two more years to see what happen. Hug~~
