Hello and welcome – Graves’ is much more rare in children than adults, but that is AWFUL that the school isn’t recognizing this as a serious condition. I’m including a couple of links below, but check out the “Students and Graves'” bulletin first. The school needs to set up an Individualized Education Plan to address your daughter’s needs while she is being treated. To not let her use the restroom as needed is just flat out cruel.
Wishing you and your daughter all the best!
