Yesterday our PT (this was her first time seeing Elliott) suggested that because he sleeps in the fetal position, we should put knee braces on him to keep his knees straight. So she gave us some braces, essentially what you get when you blow your knee out and they don't want you bending it. Elliott is great with his night heel braces, 'boots' as we call them, but he wanted no part of these knee braces. I'm wondering if anyone else uses these, or has had them recommended. I don't recall reading about anyone using them in the message board, so I'm curious. I'm wondering if these are really necessary...
