Oh, lighthouse,
This is my 'wisdom' on 'helping' older people.
"Let 'em whirl" as best you can.
Even when it may 'shorten their life" or "be bad for them".
Change is hard at any age, and change forced on you at an advanced age can be horrible, counter productive and useless.
I know it's hard to see your Mom overdo, and your Dad be demanding.
But this may be what they 'want' , what they are used to.
When my in-laws were so disabled they had to be in a nursing home, my father-in-law chose a place
near their home.
EVERYONE in the huge family (11 kids) had different ideas about where they should be located.
BUT my father-in-law was perfectly competent to make his own decisions, and that had to be respected.
At least I think so.
The same thing applied to his eating sweets when he shouldn't, etc.
It is so easy to patronize and infantilize older people when you 'know what's best for them'.
And even easier when YOU have to bear the brunt of the penalties for their choices, as the 'responsible adult" picking up the pieces at the emergency room and with the financial and health disasters that may ensue from poor choices.
And yet, I say "try to let them make decisions and do those things that they choose" without too much interference and judgement.
Remember, one day your kids will be patronizing you, trust me. I'm already there and it is infuriating!!!
At least I've tried to 'model' the appropriate way to treat older people, even if it hasn't 'taken' all that well, it seems.
Good luck lighthouse, this isn't a bit easy.
Hugs
Elaine
