It's not bad but bad enough. He has heart issues and lung issues. He has copd, emphysemia, icd/defibrilator. He isn't doing much on the fitted sheet, but when he does, it is just very smelly and messy. Of course, I change them, but is there a way I can do this without having to change the sheets daily? He is 83 and able to dress, bathe, etc. by himself. He is on oxygen 24/7. I am retired, so I can be there for him.
