Well, my 2 1/2 year old son, has developmental delay. He has been tested, but he has not been diagnosed with autism or adhd or anything.His pediatrician has stated he does not have autism, because, she has done the tests she needed to rule that out. So, now he's going through speech therapy and cognitive therapy. I feel he is just as smart as any other child his age, however, he cries and whines constantly, if he's not watching T.V. He moves his and fingers strangely. He has not said mama or dada, but he can up to 10 words. He constantly pulls his ear, as if he talking on the phone. He will wave bye, bye and say hey or hi. He will play with other children. These are results from his evaluation; Gross motor-17 mths, Fine motor-20 mths., Receptive communication- 13 mths., expressive communication-10 mths.
