She is in an assisted living facility but I do her laundry. She keeps herself very clean but clearly she has issues because there are panties washed out and drying in the bathroom all the time and sometimes she doesn't make it to the bathroom in time for bowel movements either and that is a whole other problem. She denies any problem.
Another is having her doctor talk to her about the problem; my mother very good at following doctor's orders, and hers made it clear that she was to use protective garments so as to prevent utis or somesuch.
