I agree with everything spaghetti said. I have one thing to add but I have no idea if it'll be effective. My son also has dysgraphia and DCD. I came across this book earlier this week and we're giving it a try.

Basically, it is an 8 week long strength training program for kids with dyspraxia (term used in UK for DCD). DS9 and I are doing it together.
