I don't get it when people who haven't had young children to care for in years expect the day to be ALL about them. A card, phone call, yes all appropriate assuming no toxicity. But most of the day should be spent, in my opinion, honoring mothers with children still in the home. Just my opinion I know, and getting slightly off topic.
I guess I understand this point of view but I don't agree with it. No, the day shouldn't be "all about" either of the mothers specifically. If possible, it should be all about all of them. Now, again, this is all assuming normal re-lationships, reasonable proximity, etc.
If/when my children have children, I'll be thrilled and proud to share the holiday with my grandchildrens' mothers. I would not appreciate being told, in so many words, your day has passed, it's NewMom's turn now. Mother's day is about all mothers, not just those of children of a certain age.
By your "in the trenches" reasoning, once the kids are over a certain age, their mother really shouldn't expect much, if anything, for Mother's Day since she's not caring for small children anymore. My mother was my mother till the day she died my love and appreciation of her, instead of diminishing since I didn't depend on her 100% anymore, actually grew as I got older.
Sorry to derail, but this is something I feel pretty strongly about.
