Someone here on TP suggested getting pillow cases which were a bright strong primary color different from the other bedclothes. It helped. And he could orient his position. Perhaps it would help your hubby.
We've just been out for a lunchtime meal. There were thirteen of us from the flats and we went in four cars. We went to a local garden center and had a table reserved and we had table service. The food was good and my husband ate well. The only problem my husband has sometimes when he's eating is his nose runs, and he doesn't seem to notice. I had thought about not going for that reason, but I hoped it wouldn't happen. But it did. When I notice I tell him and he uses his hanky, but I don't always notice in time. At one point the lady opposite handed him a serviette. He doesn't seem to be embarrassed by it but I am.
This is the very first time that I have found this problem (runny nose and not noticed). My husband has the same and I mean very much so. Sorry you-all are going thru this but as they say "Misery loves company."
