Can anyone recommend help to get DS tying his shoes? He had small motor issues when he was younger, but hasn't had any issues in three or four years. I don't know how much is true problems and how much is stubbornness. But he's going to be eleven shortly and I'm tired of doing it for him (sports practice) or having him wear crappy Walmart $9 shoes.

I'm not looking for a work-around, but help in learning to do it himself. Can anyone link or recommend something?
