Mothers Day matters most with young children

I agree op. Plus It’s just a Hallmark event and encourages/guilts people to needlessly spend money. My own DM has said for years ‘don’t bother, I’m not fussed’, although I do always go over either the Sat or Sunday. I take a card and a hamper of edible treats, but I don’t ever expect anything from young adult DC than a card & a hug. I certainly won’t expect to see them when they move out and have their own DC. Mother’s Day is for little DC and young mums imo.

@Bignanna the op is right above yours, we know what you are replying to.

I think it’s for elderly mothers and mothers with young children but also those who feel they don’t get appreciation, as an acknowledgment that they are actually appreciated! Personally I’ll be working and dh is away so I’ve just been hinting to the kids that a card would be appreciated and will ring my mum on the day

Personally, I never really cared about mother's day growing up and I don't really care about it now in respect of my own children. When they're very little, you know anything you do isn't coming from them - probably still the case until they're reasonably old actually!
Mother's day mattered most to me when I wasn't living with my own mum anymore (because I was an adult!). It was always nice to make a bit of an effort to take her flowers and drop in. Now she's gone, I am even more set on this idea.
You're right though about those very early years being the most full on!!

I think as children age there are different challenges, and being a mother can still be all consuming, albeit in a different way, for as long as needed. Mother’s Day mattered to me right to the end of my mother’s life, and it still matters that my children see fit to mark it for me.
