I have a 5 year old student in my class who is not toilet trained. We make him sit for 5 minutes on the toilet three times while at school. Each time he pulls the pull up down, he has dried pastey feces in his pull-up. He has never fully had a bm at school. HE refuses to eliminate his bowels at school and has only urinated once in the toilet. Pullup is never soiled with urine just pastey remnants of feces. Mom has said he has had constipation issues in the past!
