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.

Just another man inserting himself (and his kids) into a situation that has nothing to do with him. Theyre not being singled out, other spouses are also not invited (RTFT). what 13-16 year old want to attend a 90 year old womans birthday when they dont know her ! (Again read the read they have no relationship with this woman!!!!)

Oh for goodness sake. You're suggesting these 13/14/15yos' mental health is going to be negatively impacted by not being included in photos at their stepmother's grandmother's 90th tea party? Really? Even if they knew this woman really well, you don't think that by that age they can't handle the truth of not being everyone's biological child, grandchild or great-grandchild? Another way these teens' parents are failing them.

Will the cousin's biological children's mental health be negatively impacted if they aren't included in their 13/14/15yo step-siblings' grandmother's 90yo's tea party photos? No? Didn't think so.

It's just nonsense, all this foisting of "relationships" (they're not relationships because it takes at least two to form a relationship) onto people who don't want them. And BS to "but won't anyone think of the childrennnnn?". The people who should be thinking about the children are their parents, specifically this idiot man who is foisting his teens onto people at public occasions for his own, selfish reasons to do with his own failed relationship with their mother. It's such hypocrisy, made worse by randoms accusing a 90yo woman of awful things and calling her vicious names. MN is like the twilight zone sometimes.

Are you quite alright Cankles?

There is nothing lovely about a grown woman excluding children.

The stepchildren are maybe 13/14/15ish. They have been in my cousin’s life for maybe 6 years.

When our mutual cousin got married they were probably 8/10 ish. Their father brought them to the service uninvited and not appropriately dressed and they are positioned outside the church next to cousin’s actual son (who has no real relationship with them). He then brought them back in the evening and called them over when photos were being taken. They had buffet and used the free bar.

They have no independent relationship with our family.

I understand that he brings them uninvited to lunches/dinners that in-laws host.

Cousin’s actual children are of course both invited. What reason would you give to them especially the 11 year old for not taking them to a family party? Surely he and the half-brother in a few years would realise that the older kids aren’t related to grandma and they wouldn’t go to the other kids’ family occasions. They would then have to see the significant photos with ever other great-child in them?
That would be heartbreaking.

I totally get wanting a photo with just your great grandchildren on some visceral level and airbrushing them out after would be odd.

The collateral family e.g. nieces and nephews’ spouses aren’t invited; one nephew did say that his wife would like to come but accepted the reasons graciously.

I know I mentioned a bar but it is not a pub it is a proper hotel sit down meal.

Ok but 6yrs is quite a long time isn't it? To be fair this isn't the kids fault and there is no reason to treat them like they have an agenda.
I used to be a step parent and still count myself as one. Nobody would bat an eyelid in my family if we turned up to dinner and she happened to be with us. I still turn up to dinner with her sometimes and I'm not even with her Dad, my brother sees her more than I do as he lives around the corner from us and she looks like my son. I feel like you are being a bit mean here.

Obviously her husband is making the fuss and I assume he's invited due to his with wife being your cousin and now wants his kids to come too. Obviously she may decide it's not worth hassle/grief she is getting at home and you might not get that photo of you all with your grandmother.

It’s the other dad that’s sitting in the bar, he sounds a bit of a shit stirrer too to be fair.

Why doesn’t gran like the teens OP?

Why is he being a shit stirrer, he is sitting at the bar so his child can attend as mother wont take them

WhatNoRaisins · 30/01/2026 16:23

Give that there isn't much of a relationship between this 90 year old and her teenage step grandchildren I really don't see why this is such an outrage. Unlike that other poster who keeps posting drama about her slighted older daughter these teenagers even have two involved parents, they aren't hard done by.

Agree with PP, the cousins DH sounds like a shit stirer and I bet these teens don't even care.

Picklelily99 · 30/01/2026 16:26

Way back at "all her descendants" my eyes glazed over, and I lost the will to live!

You're right and I'm sorry 😂I'm finding myself disproportionately pissed off by this. I think it's another form of entitlement, which I'm dealing with the fall-out of in other aspects of my life right now. People are so unreasonable sometimes! Everyone should just stay in their lanes. In fact, nobody should ever marry, nobody should have children ever and nobody should ever celebrate their 90th birthday - that would solve everything! (joke - just in case)

NorthXNorthWest · 30/01/2026 16:27

Grandmas party, Grandma's choice. Her family are entitled to marry/ have children with whomever they choose but Grandma does not have to accept step children if she doesn't want to. Especially not if their father has form for pushing them on their family. The shared child should go the father is being unreasonable.

Ophy83 · 30/01/2026 16:30

If she wants your cousin there, your grandma has an easy choice.

amyds2104 · 30/01/2026 16:32

I also think grandma has a right to choose who to invite. It’s a bit shitty to exclude children but if she wants to act that way then if you live till you’re 90 then you can do what you want. I don’t think I’d attend though if it was going to upset my husband or step kids. We are a team at the end of the day and come as a package but all families are different. No right/wrong answer because it’s family dependent.

NorthXNorthWest · 30/01/2026 16:33

Thanks to the levels of blended family entitlement on MN I would never form a blended family if I found myself single. I would certainly caution my children against it.

Rubes24 · 30/01/2026 16:33

As part of a large extended, family including multiple adopted children, this makes me really sad. My adopted cousins and their children are family regardless of genetics and they were just as adored by our grandparents as the rest of us.

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. They're her great-grandson's siblings.

Sorry but I don't think your grandma is a lovely woman if she's content to exclude children and stir family conflict like this.

Grandma can invite who she likes and invitees are entitled to not attend and to keep their children, shared or otherwise, at home too.

If you read all the posts by OP they really have nothing to do with granny.

Faceonthewrongfoot · 30/01/2026 16:40

I understand that he brings them uninvited to lunches/dinners that in-laws host.

So the kids are regularly left out of family meals and events? I can see why the Dad is pissed off and just brings them anyway tbh. I could sort of understand when it was just Granny's 90th, but this additional information makes it sound like you all exclude them all the time.

(And the mention of the 8 and 10 year old 'using the free bar' made me lol - knecking the vodka shots were they?)

No, they aren’t. Even if they were, they aren’t the only ‘family’ excluded.

The one stirring conflict is the cousin’s husband, who is throwing a strop because he’s not getting what he wants. He may not like their stance on his children (which is not even an abnormal or unusual stance), but this is the family he married into, and he doesn’t get to force his vision of an ideal blended family onto them.

BowstotheSettingSun · 30/01/2026 16:35

They can in indeed.

They can't expect that people will treat new children in the blended unit as blood. With respect yes, but people don't have to consider as equal to blood relatives as blood. Forcing it or judging others for not putting those new member on the level you have will never end well.

RisingSunn · 30/01/2026 16:42

The cousin’s entitlement is off the scale!

Just let grandma have her day fgs.

Well she's got a choice. She can either suck up the possibility of them being a photo or she can cry over how her action in excluding them means someone will be missing from her precious photo.

Her action. Her choice. At 90, she should have worked out that actions have consequences and you can't be a dick to someone and then expect them to do things on your terms however much you think you are in charge.

If she's been a dick and wanted to exclude someone then its her own fucking fault. She can't complain.

Midmeddlecum · 30/01/2026 16:44

Granny’s not a very nice person.

NobodyAgrees · 30/01/2026 16:47

The children aren’t related to her, I don’t see the issue with them not being invited. I doubt teens would be excited at the thought of a 90 year olds birthday party anyway.

Unlisted · 30/01/2026 16:51

He brings them uninvited to pubs and restaurants and expects his FIL to pay for them.
