This keeps happening though. Schools have ended up taking more and more parental responsibilities of feeding, nurturing, and now changing the nappies of children, all of which is making the role close to impossible and taking away from the primary purpose of schools, which is to educate the children, not parent them because their own parents can't be bothered.
It cannot continue. If a parent has decided not to potty train their child, it is their responsibility to change the child and it is them who should be charged with neglect if they do not come to school to change them.
