I'm so glad you said this op! It's exactly what I was thinking!
No I'm not dh's mother, that's pretty obvious, don't need that reminder. But I am the mother of his children and responsible for the largest part of running our family and household, which he truly appreciates! He shows me this appreciation all the time (oh yeah, and we also don't need to be reminded there are 364 other days in a year
but on MD I get a little extra something, a card with my 2 year olds' scribbles inside which I shall treasure forever and a token gift which for the second part I'm not even as fussed about, but it does feel nice. I also get to spend time with them as a family and a few hours to relax by myself. I feel loved and appreciated and on that day I think wow, I really must be doing a good job at this mother/family thing (and who doesn't have doubts about that from time to time.) I love showing our appreciation for dh on Father's Day too.
If people think it's commercialised bullshit and husbands shouldn't have to involve themselves in any acts of appreciation to the mother of their children, then that's fine, feel free to have your opinion, but that doesn't make it the right one. It's up to us as individuals as to how we choose to view Mother's Day. Who are they to tell a woman how she should be feeling when she's obviously feeling upset and under appreciated by her family. I've had enough of men telling me how to feel thanks, so won't be accepting any of that bs on a day like Mother's Day from fellow females.
I think they should probably stop celebrating their dh's birthdays by this account, and not give their kids any help with the occasion either, as it's not like they gave birth to dh on that day, so it's pretty meaningless and nothing to do with anyone else....
...Or we could just celebrate the few things that are worth celebrating in this short, short life. Celebrating people I love is high on my list, on a regular day and even more so a specially celebrated day.
