So there is no genetic test for EDS? I am wondering if we should get DS evaluated for this. He was diagnosed with benign congenital hypotonia as a baby and is still hypermobile. He also has GERD. I am not aware of any other problems, though he seems to tire more easily than other children (he also has asthma, though). He is only 5 so writing isn't a big part of his life yet, but I don't see any issues with it. One thing we do notice with him is that he drops things a lot--cups, forks, food, pencils, whatever. It's like he can't maintain a hand grip very well.
