In the last two weeks he has started peeing on his clothes when he goes to the bathroom. He is not incontinent. I don't know if it is his balance, dementia or aim but he pees all over his pants and sometimes his shirt. I have asked him to sit down to pee. I have taped large reminders but he refuses to sit down. We are doing multiple loads of laundry a day because it happens every time he pees. When he does sit down his clothes do not get wet. HELP! Is there a way to lock the lid?
