My father has dementia and my mother cares for him. In addition to the dementia he also has severe CHF and tires easily. Trying to bathe him sitting in a shower chair has turned into a big chore for her because he gets weak quickly and complains about the cold. The last time I tried to help give him a shower his blood pressure dropped and he passed out. I was wondering if anyone knows if the disposable washcloths that you can get from Amazon or a suitable replacement for showers?
