I have bought him depends but he will only wear them outside his apartment. He has ulcerative colitis that is very bad and takes medication for it. His caregiver tells us he has accidents and doesnt rinse out his under pants and throws them in the laundry hamper on top of his other clothes. This is a very disgusting habit. How can I get him to stop this or at least rinse out his underwear before putting it in the hamper?
