My dad has stopped wearing underwear, he won't take a shower or get in the tub to bathe, he says he say's he's afraid because he fell in his bathroom when he was living by his self before he got sick. He'll let the hospice health aid shave him and wash his head and upper part of his body but not the rest. He does wash the rest of his self off and will change his pj pants regularly, but I don't understand why he won't wear underwear. Anyone else experience this?
I installed a bidet for grandma years ago. It does a world of good for people who won't shower. They are really cheap now, like $20.
You only mentioned him wearing pajama bottoms. Maybe he would wear underwear if he had pants (trousers) on.
My dad never liked the feeling of underwear when he was in bed. He said he had to keep pulling them down so he just wore the pj pants.
