Nice to know! You're a plethera of knowledge for me, polarbear - seems like all the stuff I am embarking on you have already btdt to some extent!
Anyway, I think it has something to do with just helping neurological issues in general (DS hypotonia is allegedly neuromuscular) so therefore they are finding it helps with a lot of stuff ... I have no idea, really. He really has relatively poor executive functioning and processing speed in my opinion; so even if it didn't really help with hypotonia per se it would be nice to see that other stuff improve, ya know? I have no idea - I am kind of talking out of my butt, LOL. I guess I'll see what the OT says about it. But nice to know your DD did well with it. Nice that your insurance covered it!
