This is a serious, genuine inquiry. I'm not just sniping at my MIL. She is 81. She's a handful. Lives in her home, with a full-time caregiver/companion whose main duty is to make a fuss of MIL and pay constant attention to her. It's more personality issues than dementia.
However, MIL has never had a sweet tooth that I remember and I've known her for 34 years. She takes tea and coffee black, without sugar. Not big on desserts or cakes, never noticed her tucking into petits fours after dinner. The most I've ever seen her enjoying is plain, boring shortbread and for a reasonable cook, she's never had any interest in baking or in serving proper puddings at family meals (humph!).
All of a sudden she's almost literally taking candy from babies in her craving for chocolate and it emerges that she flips out if she goes to a house where there isn't Diet Coke and ice cream available. As told to me separately, by my BIL and my son, rolling their eyes.
It isn't that I don't see why a woman of 81 shouldn't have as much ice cream as she likes. It's the radical change in palate, and the somewhat extreme appetite for sweet things that's troubling me. Shouldn't it be reported to her primary?
