Teachers and their aides in the Buffalo Public Schools are concerned with young children who come to school without being potty trained

They want the district to do something about it.

The teachers' union said some kids in Pre-K and kindergarten, mostly between 3 and 6 years old, don't know how to properly use a restroom.

Union leaders say it's not in their contracts to change diapers and soiled clothing.

And when it happens, the cleanup often falls on the aides because teachers can't leave their classrooms.

State education department guidelines say schools must accept Pre-K students and kindergarteners even if they aren't toilet trained.

The Buffalo Teachers Federation president said the school district needs to come up with a solution for the aides.

“There, first of all, needs to be a designated room where this is done,” said BTF President Phil Rumore. “They also have to have shots before you do this stuff so you don't catch any diseases. Also, they should be paid extra because this is going above and beyond what they're paid to do.

The Buffalo Public Schools said in a statement that the district is willing to continue talks with the teachers' aides to find common ground.

State guidelines also suggest schools work with parents to help them potty train their children.
