I so happy this is finally happening for him. I made a comment early on to my peditrician, DD was about two, this Doc had real forward thing diagnostic skills. He played with her and observed however she wouldn't speak to him but would follow directions. I had issues with our school district cause she was 2 and they didn't want to take her for early childhood intervention. My peditrician told me they MUST. Long story but Easter Seals helped me in so many ways with her and how to make sure the schools did everything required and how to present to the district. When her IQ was tested they did not want to write an IEP for disability being non verbal and an IEP for being Gifted as her IQ was very high. I won that one two but you shouldn't have to win and fight for your child to educated properly. And there is when I pounded a sign in the ground, got a petition to be placed on the ballot for our elected school board. I didn't want other parent to have to continue to fight for services, we had the freak'n special ed staff already.
Any who it all did work out in the end. She graduated from a top University with a double major in Math and Statistics. Yesterday at work a presenter from her department called in sick and 20 minutes prior they dumped a presentation to the staff in her lap. She pulled off the speech before hundreds of people without any prep. So with the right services it amazing what our kids can pull off. I hope for the same with your son.
