I may totally be jumping the gun here--but I have this "gut" feeling that DS1 is dyslexic. He has speech apraxia and sensory issues---and I'm currently trying to work with his school therapists for a stronger DX because I truly feel he's dyspraxic. But his OT doesn't think so--just is calling him clumsy at this point. I truly think there's more to it.
So what's making me think this is that when he writes his name--which he has tons of trouble with--- he was writing a few letters completely backwards---and then he went to actually writing them in different orders--and now he's actually writing his name completely backwards. So he "may" have the write letters written the correct way 60% of the time--but actually writes them in reverse order (like standing in a mirror).
I'm just curious what your early symptoms were for dyslexia and how it was diagnosed. Neurologist??? I don't want to miss something like that--and not sure where to go next.
