90 year old grandma and cousins’ stepchildren

My grandma is 90 and there will be a massive afternoon party for just two hours in a hotel paid for my mum, aunt and uncle.

All her descendants, their partners plus nieces and nephews without partners and one surviving sibling and two of her surviving cousins, one with husband. The surviving sibling and cousins will have one of their children with them given their advanced age.

Grandma does not want my cousin’s two stepchildren invited , they are teenagers who live almost exclusively with their mother.

Cousin has said her husband doesn’t want her to go with her elder child and their joint child.

Elder child’s dad has stepped in and insists that he will take child himself and sit in bar to wait for him.

My cousin, brother of this cousin is coming home from Japan for this.

My aunt has said she will make sure their joint child will be there as well.

What for you all think about this? Is cousins’ husband unreasonable.

I don't see how you'd invite boyfriends and girlfriends of grandchildren but not stepchildren. They're equally related.

By the same token, why not invite his parents too?

The spouse is invited as a plus one. Her grandchildren are invited because of their relationship to and with her.

They arent essentially strangers. Apparently she will be broken hearted if theyre brother isnt there. She knows exactly who they are, they arent randoms off the street.
But because shes old, no one pulls her up for being awful.

Okay then, they’re as familiar to her as someone she’d recognize at living in her general neighborhood, that she’s briefly met a handful of times. Essentially strangers.

She’s not ‘awful’ for not wanting two teenagers that she doesn’t know, who are no relation to her, at her family celebration.

Their brother is her grandchild, and by the sounds of it their mother wants to go with both her children.

So you think it’s acceptable for someone to pick up the bill for your kids or you would be happy to have at least £50 added to your bill to pay for your grandchild’s half siblings?

No, if BOTH my children- my daughter and my stepdaughter- were not included I wouldn't be there so the cost would be £0. Luckily, my family aren't this awful and if we're invited somewhere as a family they invite the whole family.

My grandma is a lovely woman hence her family arranging this party for this milestone.

She is worried he will push them into significant photos.

She wants just family, cousin’s husband has form for trying to push his kids forward. He actually brought them to church for mutual cousin’s wedding and even brought them back to evening uninvited.

If he’s annoyed he shouldn’t try and guilt his wife and stop his stepson and younger son from going.

Their absence from photos will be heartbreaking to a 90 year old woman.

I think grandma is being ridiculous. Why be so precious about a few photos? Why would she want her birthday to be remembered for a nasty, petty drama?

Buffs · 31/01/2026 20:16

I don’t understand how a 90 year old can be so petty. Invite the teenagers!

HeadyLamarr · 31/01/2026 20:01

We have step children in our family. They are very happy seeing their own family members separately, and don't think distant/extended family of their step siblings are part of "their" family and vice versa.

It's just a Venn diagram where there is some overlap but not all. Everyone is respected and cared for, everyone understands that sometimes Olivia and Joe celebrate things with their grandparents, while Maisie and Theo celebrate others with theirs.

It's not disrespectful or unkind to know who you are related to in a blended family, and to be ok with that.

Cousin's DH is making an issue where there is no need. He should get over that chip on his shoulder - unless he expects his ex wife's husband's to include his step child.and younger son with their events?

I've been informed that some great aunt or something has made a family tree of dp's side of the family but left me off it because we're not married, but included my child. Any family tree that my child is a part of should also include me in my opinion seeing as I bloody birthed him. Suspect this man feels that as his oldest children are siblings with the bio grandchildren they are family by extension. Just like all the spouses who have married in, not biologically related to Granny (you'd hope) and yet still invited to the party by extension.

Imagine being so annoyed that two teenagers dare to exist.

Or them all still bleating on SIX years later than a little 8 year old hand a vol-u-vont from an evening buffet…..what sort of ‘family’ is this?

HeadyLamarr · 31/01/2026 19:44

Cousin's husband is an asshole trying to make a point. I expect there's a fair bit of tension in their marriage if he overrides her and insists on bringing his children were they aren't invited.

Gate-crashing a wedding, FFS!

These are step-great-grandchildren that don't live with the 90yo's granddaughter. Birthday Gran probably barely knows them - if at all.

For your 90th birthday it's perfectly acceptable to invite your family. These teens aren't her family. They would probably be bored to tears anyway.

The husband is a dick and I'm team Grandma.

Have you heard of a photographer being engaged for an event and only taking one photograph?

Yes, I have. I’ve just said I have. This is just a larger scale family portrait.

Even if there ARE going to be a lot of pictures, it’s right there in the OP that the grandmother wants a picture of the whole family. And that she doesn’t consider these children family. And that their father has form for trying to force this issue. It’s literally all in the first post.

That’s why there’s no point in people saying “Just invite them and take the photo without them”. It’s very clear that would be noticed and would be an issue.

The 90 year old isn't getting married.

What’s your point?

TheignT · 31/01/2026 19:17

AnnieLummox · 31/01/2026 19:13

What does wanting her actual great-grandson there have to do with her relationship with the half-siblings?

If I was getting married, I’d want my cousin there. I’ve met her half-siblings once.

Why would you hire a professional photographer to come and take two photos? Let's be honest the photo is just an excuse. If people want to exclude children at least be honest. If you're too embarrassed to be honest then do what you know is the right thing.

Sorry but if Grandma is not a nice person. They are family, they are the cousins step children and the cousins sons siblings. If it would break her heart that much she would invite them.

If i was the cousin Granny would be getting told you can have all of the children are none 🤷🏼‍♀️

Jeez I can’t imagine wanting to go to a 90th birthday meal at their ages.

OP has not clearly explained ~ the post is very muddled but I do think that Grandma should be allowed to have or not have whoever she wants at her party.

freakingscared · 31/01/2026 18:20

Don’t enable your grandmothers bad behaviour ! Tell her if she w ate the ret if the family there then they should be too !
