I suspect this may have occurred with one of my sons as well, but he’s so minimal “on the spectrum” that it’s not a serious concern. Step 1: keep doing what you’re doing. Step 2: work around the difficulties in his life and keep encouraging him in all the ways he’s great at one thing or another. Step 3: Even with difficulties, I think you’ll find unexpected excellence to him that is heightened BECAUSE of the limitations. Basically I’m telling you to Helen Keller him.
Thank you for the encouragement. I once got to meet Temple Grandin, who is the patron saint of Autism. She told me to keep the bar as high as possible, which is what I do (or at least try to).
