My mother in law is incontinent and CHF. As she is on diuretics we try to keep her on a two hour bladder schedule to prevent leakage. She wears depends. Every time I try to remind her it has been two hours, she insists that she doesn't have to go! It is very frustrating as she does not argue with her health aid or anyone else, just me. I am her caretaker. Is this a control thing?
