Thanks to everyone who responded. I think I agree that what my Mom should really be getting is skilled nursing care, if her mobility doesn't improve--and it looks like it is only getting worse. My sister promised Mom she would never put her in a nursing home, and I told my sister long ago she should NEVER make a promise like that. The house is my mom's--she paid for it--and my sister really wants Mom to be able to live there and enjoy it, and she has already talked it up with Mom, and I'm afraid she got ahead of herself, and has done so because she's so determined to not put Mom in a nursing home. I plan to talk to her about it once more, but my sister never listens to me; maybe she has to see for herself just how unworkable this crazy plan of hers is.
