We had issues last year with teachers at school being angry at her for not using her right arm to do things like cut paper, but her old brace had a stay that immobilized her elbow and didn't allow her to bend her arm. She would ask for help from a classmate then get clipped down. We ended up just doing away with that brace at school since no one could seem to understand when it would be appropriate and helpful to remove it for her. When it was removed, it was not put it back on properly. This situation was frustrating for M and me!
We got the script for this new brace from her orthopedic doctor before school let out in May. It would have fixed all of the issues we were having with the old brace (I think) but then again so has home schooling!
