I was wondering about this too. Would this help for missing days of school because of celiac pain? My daughter was diagnosed a couple of months ago and has missed quite a few days already because of it. What else is it good for?
It's also good to have a "same page" mentality. If you talk to the teacher about unrestricted bathroom access and she abides. Great. But what about when a sub shows up, your kid has an issue and runs out of the room? That's not fair to the kid that everybody doesn't follow the same rules.
