I've seen many residential care homes that only have a few people living in them, and they are quite nice. If you feel your father might be happier there, you might want to check some out. They do have a homier feel to them, and the one I visited had a vegetable garden and a lovey living area where folks could visit. I was very impressed. Plus I think they give a little bit more personal care since their are fewer people. You just never know -- some folks are better off in bigger environments with lots of people around and some are better off in a homier, small environment. Good luck to you and keep us posted; I know I'll soon be in the same predicament.
