I had a hard day taday. I spent the day on the phone w/DH's 2 cousins (separately). Their DM is DMIL's Sister. She is also gittin' Alzheimers. I had ta help her DS (who lives w/her) know how ta handle her. (That sounds terrible.) It brought back so many bad memories.
I had ta tell him things like;
You can't bring her back into this world ya have ta go to her world.
Never say no.
Never ask "Don't ya remember?"
If she can't do something, act like it is hard for ya too.
If she says no then try again later. She will have forgotten that she said no.
It's so hard ta make 'em comfortable.
