Dad wears Depends day and night but wont pee in the toilet. His Depends get filled and he has wet clothes and furniture. When we remind him he says he already went or I do use the toilet. We try to make it routine like before meals but he says I dont have to go, He refuses to change his Depends during the day. It's often difficult to get him to change them before bed. He wakes with wet clothes and bedding. (we do use bed pads to save the mattress). Any suggestions?
