Did you mention it to her?
My mom is almost 86, she lives with my sister (who's never there half the time) still does well in most aspects of life, but she does forget sometimes, or repeats things that she's already told me, asked me.
I would say it's kinda normal? Maybe get her a date book and write all important dates down for her, so she can refer to it??
My mom writes EVERYTHING down, like a daily diary kind of thing..Your mom sounds pretty great for her age..I would think if she feels good, is doing fine with daily life, I'd chaulk it up to normal aging process..
Heck I can't even remember my anniversary LOL
