Relative took my niece and missed my child's party

Please bear with me as this is long but I don't want to miss details out.

It was my child's birthday and I'd organised a small party after school with them, their sibling and 2 cousins who are also siblings (and who we are very close with) - 4 children in total.

The morning of DC's birthday, I found out from another family member that she's taking one of the cousins away for a few days and that child won't be attending. The plans were last minute arranged very late the night before and purely so parents didn't have to parent.

Side note: I'm also close with this family member as she has my neice/nephew for childcare and we meet up a few times a week with the kids.

So, when I found out she was taking her, I was absolutely devastated. It meant a lot for both cousins to be there to celebrate my child's birthday. They'd agreed to come and I'd made a cake, sorted food etc. because it was such a small gathering, their presence was missed. This family member knew all of this and decided not to mention to parents or try to resolve it.

To be clear, before the relative left with my niece, I expressed my upset and disappointment. She told me she understood etc. and admitted that there was no reason for the niece to be going other than it been a break for parents. Obviously this didn't seem like a valid reason to miss a close family members part to me and I reiterated how upset I was. Family member did nothing.

I told nieces parents that I was upset and they said they hadn't thought it through, it was last minute and apologised. I was still upset but ultimately I accept this. They didn't know how I felt until it was too late.

However, I was still feeling really hurt the next morning and actually, things had progressed to anger. I messaged the relative calmly (at first) to get it off my chest. I told her that she could have said something to the parents, especially after seeing my hurt and upset. I told her I felt like my child wasn't a priority. I honestly feel like she shouldn't have gone, told the parents that it wasn't fair to my child to not have everyone there to celebrate them etc.

She said sorry for not calling but quickly followed this up with excuses and said she was trying to help (obviously not my child or me). She said she didn't think I'd minded (after I explicitly expressed my feelings before she left). Honestly the message felt insincere, dismissive and unapologetic. There was no accountability.

I was fuming after that and message back saying it was 'bull💩' she didn't know as I told her and she saw me.
I told her she let me and my child down.

I know this is harsh but it's also true.

Her response was dismissive again: 'im
sorry you feel that way'.

I blocked her after that message as I realised she either didn't actually care how hurt I was or couldn't accept any accountability and I wasn't going to get an apology or the validation of my feelings I needed.

I'm sure this is a bit U. But am a unreasonable expecting her to put my child first given it was his birthday, the birthday plans were made and their new plans were VERY last minute and could have been easily cancelled? Like I said I was close to her so for her to see how upset I was and not act isn't something I feel I can easily forgive. AIBU?

Devastated… over a no show at a kids party. It’s feel extreme and is this really what you want to teach your child? Plans do change and we can adapt and enjoy the company of those who do show up.

Stressmummy12 · 22/05/2026 22:00

You need to get a grip and stop over reacting.

FrenchBunionSoup · 22/05/2026 21:58

The parents shouldn't have changed their plans (and should have let you know in any event).

But you've been massively unreasonable and inappropriate with this other relative. Getting angry with them and saying she was taking "bull". You owe that relative a big apology.

Pistachiocake · 22/05/2026 21:56

Who is the relative? Fine if you don't want to say, but if it's the grandmother, she might be genuinely worried about the niece whose "parents don't want to parent" and "play computer games all day", and worry that if she doesn't do what they tell her, she'll lose all chance of contact with the girl, leaving her more at risk.
While it's rude and annoying a kid missed your child's birthday, what is far more serious here is parents who do nothing but play computer games and don't want to parent-if things are as you say, that's what would bother me.

Goinggreymammy · 22/05/2026 21:54

I dont understand why you didn't express your disappointment to the child's parents yourself before they left, and not simply tell the family member (sounds like your mother) that was taking the child you were upset. Ultimately it is the responsibility of the parents to decide if their child (your niece) goes off for a day/sleepover or whatever.

I dont see why this had to end up being so dramatic, it is out of proportion to normal thinking

Jk987 · 22/05/2026 21:48

That was a really long and detailed post for a short story.

yes be pissed off but then move on, don’t cut off contact with your close relatives!

Moonnstarz · 22/05/2026 21:47

The thing is you mention you meet up several times a week with the children so I am not sure that this 'party' would have been seen as anything too different to normal.
It wasn't like you had paid for a party at a venue, it was food and games at yours.

What you were doing sounds more like the kind of tea party you might do with just the parents or maybe invite grandparents round for a piece of cake.

As someone else said, only inviting the cousins could have meant that neither attended had one been ill.
Surely doing something small scale like this is usually intended as a low key event.

Also wondering whether your weekend plans involve a proper party for your child you aren't mentioning?

PoppinjayPolly · 22/05/2026 21:45

The unblocking will only work though won’t it if the relative hasn’t noticed the blocking and either blocked back or deleted!

Lovephil · 22/05/2026 21:45

Annoying, but not worth all this drama.

JustSawJohnny · 22/05/2026 21:43

Wow. You sound like such hard work!

If you have a small party you do so knowing life happens - any of those kids, including yours, could have come down with sickness and had to miss it.

It's all so dramatic, honestly.

I can't believe you're sending angry messages and blocking people over such small issues.

JustGiveMeReason · 22/05/2026 21:42

Shame there isn't a poll.

I agree with most. The parents shouldn't have let the child drop out, once they'd agreed to her coming BUT your response is ridiculous.

Most people would have been annoyed and disappointed, but got on with the party and left it at that. Your actions are completely OTT.

gillefc82 · 22/05/2026 21:42

If they had accepted the invite then it is poor form to make alternative plans at the last minute, so I do get you being disappointed/upset. However, and I say this kindly, this won’t be the last time that children that have been invited to your DCs parties end up not attending, not RSVPing, dropping out last minute, so I think you need to use this as an opportunity to build some resilience to these kind of situations. Even more so given there is a family connection involved.

In your shoes, I’d suggest you unblock and when the relative is back from their break away, get some time for a face to face to clear the air where you can honestly and openly express how hurt you were personally and on behalf of your DC. Then draw a line under it and move on - I’m sure there will be plenty of future birthday gatherings that everyone will be able to attend and celebrate as a family.

Rosecoffeecup · 22/05/2026 21:40

I understand why you are annoyed but equally this sounds like a huge overreaction, particularly when you all see eachother multiple times a week. Your child won't remember this and will presumably be seeing their cousin in the next few days anyway?

Move on with your lives

tara66 · 22/05/2026 21:40

YABU. 4 children does not really make a ''birthday party''. It was just a very small group. You should have invited more children - then an absence of one child would not have been such a disaster. Your relative probably thought her child would hardly be missed at a ''real party''.

Moonnstarz · 22/05/2026 21:36

It's not unpleasant, more the truth.
@Familygal1 hasn't stated what the holiday was but I would guess this would appear more interesting than a 2 hour (max) get together with cousins which can happen any time.

I wonder what she would have done if it was reverse?

I think there is likely to be a bigger back story to this, but on the face of it, yeah it's annoying thet agreed to it, but as it was only something small that could be done any time then I can see why they went for the holiday.

No it's not the truth! It' s your OPINION.

Moonnstarz · 22/05/2026 21:36

Somethingbland · 22/05/2026 21:33

But this idea of a party for 4 children doesn't really sound much fun,

It might not sound like much fun to you but it obviously was what OP thought her child would enjoy on the day!

Perhaps the type of celebration you count as fun wouldn't be fun for OP and her child.

I can't believe the unpleasant attitude of some of the pp on this thread.

The little party you had planned could be held at any time.
You are disappointed but I doubt your child would be. You did it on that day because the weekend wasn't convenient for you, likewise the weekday turned out to be not convenient for them. I am sure you could host another cousin get together and play the games you wanted to.
It might be better to scale up and invite grandparents and any other relatives along to give it more of a party feel though rather than a cousin playdate.

This would be so much easier to follow without all the needless attempts to anonymise who people are.

OnlyOneAdda · 22/05/2026 21:33

I realise this may not be the case and I’m reading too much into it but how your post read to me with the last min taking the child so parents can have a break, having not thought about the birthday, apologising but not really engaging too much (“I’m sorry you feel that way”) - vibes I’m getting is there’s something else going on. Maybe the birthday isn’t a big deal to them because something that is a bigger deal is their priority right now.

AImportantMermaid · 22/05/2026 21:32

Kindly, OP, you’re going to be in for a rough ride over the next 15 years if you let every real or perceived sleight get to you this way. You’ll spend your life erupting at people for all sorts of reasons. Yes, they were rude, but you’ve given them an excuse to take the moral high ground by behaving like one of them had stolen your one true love.

Familygal1 · 22/05/2026 21:30

Somethingbland · 22/05/2026 21:24

The other adults in this scenario must have known it was your child's actual birthday. And having agreed that both cousins would be helping him celebrate it on the day it was really strange behaviour to take one of the cousins away.
Unless something else was going on that you don't know about I don't understand this last minute change in plan. Very rude and unpleasant behaviour anddismissive of your child and of you OP.

I can understand why you are upset.

Thank you. I think lots of the comments on here lack empathy. I'm not trying to be a drama queen, just genuinely feeling hurt, disappointed and dismissed.

I think most of us would feel like you, but not let it out, because of all the shit it will cause, which will splatter on you, as “the villain”.
I feel for you. You just let the truth out and showed how rightfully angry and hurt you were over you and your family being so casually dismissed by people who are family with cousins who are friends.

Thank you. I appreciate your kind words and compassion. You've hit the nail on the head with how I'm feeling.
