Thank you for so many helpful posts! I knew this board would have great suggestions. I will try these.

I have wondered about vision. His table manners really are bad and sometimes I feel like he is just not...able to do it right. He could be described as somewhat clumsy, with a tendency to fall and stumble. He drops stuff and doesn't pour, snap, or button very well. On the other hand, he can hit and throw a baseball quite well, and he's above average at soccer and a good runner and a good swimmer. He is also an incredibly good reader with no issues with fatigue at all--he will read small print for hours.
