Oh! Yeah, you better get him checked by a behavioral optometrist... Only go with one through the COVD
http://www.covd.org/ My 7 year old son also has hypotonia and hypermobility. He has hypotonia mainly in his fingers and he has postural weakness as well. (When I last saw the neurologist at CHOP said they would catagorize it as mild now YAY)... Anyway, he also has intermittent convergent strabismus (basically, his eye crosses in intermittently. I only discovered this last year but apparently (according to the neurologist at CHOP) it is VERY common in kids with hypotonia (it is also a neuromuscular condition like hypotonia is). He's has been getting OT for a few years but once we added in the vision therapy for the convergence disorder I saw huge improvements in his hand eye coordination and visual motor integration, writing, drawing, etc. He couldn't trace before vision therapy, now he can. It wasn't until after vision therapy that he would color at all. The OTs do some stuff for it on their side, too. But the combo of OT and VT has really been wonderful.
If you live in the Philadelphia, PA or Wilmington, DE area I can give you some great recommendations for optometrists that are reputable and do a very good job but will not sell you on things they can not help with. I also know a few that take certain insurances.
