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.

Well tbh if hosts really wanted them there I'm sure that my mum would have understood for a meal for a couple of hours.

I don't really see it as a "go fuck yourself".

In Op's case it sounds as if people would make sure she didn't have to seem them much/at all & will make sue that she gets the photos she wants.

I just find it very odd that you would throw a party in someone else’s honour, but invite the guests YOU want there. It’s like these people who buy “presents” for spouses or the wider family that they actually want for themselves.

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?

Yes just as I would have to pick up the bill for my children's partners, and my nephew's partner's. They are family

Presumably the spouses have impregnated/ given birth to the blood family descendants whom she wants at the party. That's very different from the two entirely unrelated step great-grandchildren.

So if one of the cousins didn't want/couldn't have children then their spouse isn't invited? I didn't think it could get nastier and then it does.

As it’s a professional photographer have some with them in and some without. Such drama. And for the record it sounds like you’ve already made up your mind despite the majority saying YABU. Grandma might be a wonderful old lady but this isn’t wonderful old lady behaviour. Your cousins husband is clearly going about things the wrong way but shows his desperation for his children to be integrated. Why are they with their mum most of the time? Was this his decision? Anyway. Happy 90th to your grandma. Shame it’s tainted with her leaving out two children.

But how far do you take it? Inviting a spouse is standard. But the relatives of the spouse? I invite my BIL to family parties, because he’s my sister’s partner, but I don’t invite HIS sister or his mother. There’s a line.

This is totally disingenuous. Of course there is a line about extended family of a spouse - but in this case it’s not extended family of a spouse - it’s immediate family of the spouse - children and immediate family of the grand daughter - her stepchildren …. and this nasty small minded family (who are still bleating on
that these children at the age of 8 availed themselves of the ‘the free bar’ and the buffet’) now want to split the CHILDREN in this family so ‘blood’ can attend but ‘married in step CHILDREN’ can’t - why don’t they go all the way and excude all the spouses? I wonder where they would draw the line if any children were adopted or fostered.

Really quite telling and gross that at a spectacular milestone celebrating with an intergenerational party - some nasty adults have this ugly focus on excluding children. I assume it’s because they dislike the cousins spouse and want to punish him - so are taking it out on the grand daughter by splitting up the children in her young family. Grim.

But that was your bloody wedding!

Why would you say to your mother “We really want to throw you a special party to celebrate your 90th birthday - but we’re going to invite people you actively don’t want there, because we’re paying, so you can go fuck yourself”?

Well tbh if hosts really wanted them there I'm sure that my mum would have understood for a meal for a couple of hours.

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.

But they are family - arent they?

On all threads of this nature, I wonder how much of it is actually about the kids and how much is about the supposed adults stamping their feet and squalling because they didn’t get what they wanted; because they want their little bit of recognition and to be made to feel “special”.

Meanwhile the kids are saying “You want us to go to a party for Sarah’s gran? Really? Is she still alive?!”

Oh, that definitely exists with some of them. Not all, of course. But there are examples of this genre where the family is actually not particularly blended and/or the kids in question don't give a shit, but one of the adults has had their nose put out of joint.

RandomSuitors · 31/01/2026 06:32

You don’t automatically become ‘siblings’ with someone just because your parent shacks up with them. I think the people saying this cannot have been the child in a stepfamily. Because it just doesn’t feel or function like that, no matter how much the happy couple may want it to. I can’t think of two people I’d less like to see than the children of the woman my dad made me live with.

THisbackwithavengeance · 31/01/2026 05:29

Are the teens bothered? My DCs sometimes get invited to my DH’s family dos, sometimes they’re not. Either way they’re not fussed tbh. It’s not personal.

I’m having a hard time imagining a 90 year old that would be so bothered about this especially as she’s not organizing thd party and is described az lovely

This!!! I smell a rat. OP, is it you who has the problem and using granny as cover because nobody would want to upset a 90 year old?

deadbobaplace · 31/01/2026 00:55

Say they can come if they really want, but as they are being invited under duress their dad will have to pay for their meals. See if he's still as keen then.

Various spouses are included?

Yes, and?

Inviting your relative’s spouse doesn’t mean you’re also required to also invite said spouse’s children, any more than you’re required to invite their mother, father, siblings, grandparents, aunts, uncles and so on and so forth up and down the family tree.

TessSaysYes · 30/01/2026 23:57

This tread has proven so triggering for some of our blended families friends

A 90 year old woman, for better or for worse, just hasn't given any consideration to that dynamic, and thank goodness she's not on here to see the horrible trolling going on

Honestly, those teens would rather go on the PS5, or chill with Friends, than attend a party for old folks. It's no Biggie for them. But the baggage of some of the posters here is shocking!

CactusSwoonedEnding · 30/01/2026 23:56

A 90yo woman is allowed to be unreasonable. It isn't very nice of her to choose to exclude her step-grandchildren but she does not owe anyone "nice". Those who love her and have a positive relationship with her can come to the party and any of the relatives who think she's a cantankerous old bag are allowed to stay away - including said step-grandchildren.

Minjou · 30/01/2026 23:54

When it was it decided that because someone acquires step children on marriage, everyone related to them has to instantly pretend they're real relations,even if they've only met them twice?
It's a ridiculously new notion, and all.you horrors calling an elderly woman nasty names need.to.cop yourselves on.
They're not her grandchildren. They're not her relatives. She's perfectly allowed to not treat them as such

In my extended family, step children are treated as children of the household.

And? The OP’s grandmother doesn’t feel the same.

So if they are a childless couple, the spouse isn’t invited?

No idea! But it's usual to invite spouses to a party isn't it?
I presume some of the photos will be of grandma, her children and their children and grandchildren, no spouses.

It seems unbelievable to me that people think this grandma, who does not want the teenage steps at her own party, should be forced to have them there.

I'm pretty sure that most of the people on this thread who think the teens should go would have an absolute fit if other people tried to tell them who to invite to their own 40/50/whatever party.

Isn't it up to the hosts to invite or not, not Granny?

When husband & I married, MIL didn't think that a cousin's step daughters should be invited.

We were paying so we invited them.

But that was your bloody wedding!

Why would you say to your mother “We really want to throw you a special party to celebrate your 90th birthday - but we’re going to invite people you actively don’t want there, because we’re paying, so you can go fuck yourself”?

All spouses that are invited are non-blood relatives and have the potential in the future of “leaving” the family due to divorce but will presumably be in the photos. These children are in the same situation yet she thinks their presence will ruin the family photos?!
