We have had an unusual number of bathroom accidents this year. Diarrhea seems to be making its way through the class.
At our school only two toilets (and one urinal) serve about 180 students. There can be wait time until there's a toilet seat available.
A young child sent to school with diarrhea is very likely to wind up having an "accident."
These accidents really do make it hard for everyone—most of all the kid, but also the staff that has to help.
Please, if your child has diarrhea, do not send him or her to school until the episode has definitely resolved itself. This will save your child embarrassment, allow us to run our classrooms according to plan, and prevent the transmission of the disease to classmates.
