To cancel DD’s birthday party because I know her dad will ruin it?

DD is turning 10 next Saturday and I’ve booked a little party for her which she has been excited about for weeks. There will be about 10 girls from her class and her cousin, so 11 children altogether. It’s only a 2 hour party at the local community hall, with a cheap entertainer, pizza and cake. DD picked the theme and has been very clear she wants it small and just her friends, no adults making a fuss.

The problem is it falls on her dads weekend. We’ve been separated about 4 years and he normally has the DC alternate weekends. I had already agreed I’d do the party and he could have DD afterwards and take her out for dinner, presents etc. I genuinely thought that was a reasonable arrangement. He does see her regularly and I’m not trying to stop him being part of her birthday, I just thought the actual party could be the thing I had organised.

A few days ago he asked if his parents could come. I said the hall is quite small and it’s a drop off party, so I didn’t think extra adults would work. Then he said his GF and her 2 children would be coming too. Her children are about 7 and 4. DD apparently got upset when he told her and later said to me she didn’t want them there because “it’s my party and I don’t know what I’m meant to do with them”. She just wants it to be her friends and cousin, which is what we had planned.

There have been a few similar things before. He does have a habit of making things into quite big family occasions. Last Christmas he brought extra relatives along to something I’d arranged without checking first, and at DS’s school event he turned up with several people which was a bit chaotic. I’m not saying he doesn’t love the children because he does, and DD loves seeing her grandparents too. I know they enjoy having her and I’m not trying to keep them away. It’s just that sometimes he seems to think every event has to include everyone.

He said his parents haven’t seen DD for a little while and were looking forward to her birthday, and that I was making him look bad in front of his family. I said they can see her, and that he can have her straight after the party and take her for dinner and cake and give her presents etc. He then said he is her dad and shouldn’t have to “book an appointment” to attend his own daughters birthday. I did get annoyed at that because I’m not stopping him seeing her, I’m saying he can’t just add 4 extra people to something that was planned as a small party.

The hall has a proper maximum capacity and I’ve already paid for it, the entertainer, food and the cake. It isn’t just me being fussy about having extra people there. If all the children come plus me and the adults he wants to bring it would be over the number we’re allowed. He says some of the children won’t take up seats anyway and I’m being ridiculous about it. I’ve told him he can come on his own if he wants to, but he says that’s not the point because his family should be there too.

DD has now started saying she doesn’t even want the party. She said she’d rather I cancel it and take her shopping and for lunch with me. I honestly feel sick about it because she was so excited before all this started. I know she is only 10 and obviously doesn’t understand all the adult stuff, but I hate that she is now upset about something that was meant to be for her. It feels like whatever I do I’m going to make it worse, and maybe I already have by arguing with her dad about it.

DP thinks I should just stop negotiating with him and have the party as planned, and if he doesn’t want to come then that’s his choice. My mum thinks cancelling would be unfair on DD because she shouldn’t lose her party just because her parents can’t agree. I haven’t told the other parents anything yet because I don’t want to start making a drama out of it when it might still be sorted. I’m also annoyed because I’ve saved for this and already paid for everything, so cancelling it feels ridiculous, but obviously that’s not more important than DD being happy.

I’m now thinking I should just tell him he isn’t invited if he is bringing everyone else, keep the party exactly as planned and let him have DD afterwards. But then I worry she’ll feel like I deliberately excluded her dad from her birthday. The other option is cancelling it all and doing something with her instead, which she is now saying she wants anyway. I know how this sounds and I might be completely unreasonable here, but am I actually the one who’s ruining her birthday now? AIBU to just say no to all the extra people and carry on with the party?

Why didn’t you book it on your weekend?

AnotherAnnie · 28/09/2026 11:35

you include your parents because to you it is natural that grandparents help, but you did not think to ask the other granparents to help. Maybe your ex did not think either.

Hopefully you will be able to include or exclude DDs family more bravely in future so this isnt a pattern and can melt into the background and be forgotten. It doesnt matter who seems to be "to blame" or who initiated coldness children piece it together as adults

Your mum is right about the fighting,. A second leg of the party could have been exciting fun for your DD if she had no idea you were fighting. Your daughter is ten and will remember her other grandparents very much wanted to be there for her, which is an upside of the sharing. Kids are strong, she will be OK. .

After four years it may be time to agree about current and future legal and commonlaw step and half siblings. And discuss future partners /gf/bf of both you. And sort out including both grandparent sets in things or not, what about uncles and aunties? With help if needed.

Your ex seems to come from a family with very different christmas traditions to you. So perhaps arrange mornings and the tree together free for all relatives and gfs and their litters, then swap who has dinner and tea(lunch and evening meal) year on year. with a formal arrangment about who gets to go to whose place etc. My family cooks extra and welcomes guests with no warning, my DHs family is much more formal so we did this exact thing, Sometimes going to another relies house for the tree, even:)

This puts a different spin on it, as he previously said it was okay and is now moving the goalposts, your first post gave the impression you hadn’t consulted him. Don’t cancel it. Your daughter should be allowed have her friends without the 7yo and 4yo. Stick to your guns. Ask him to stay for the party including the setup and cleanup, grandparents can show up 15 minutes before the end for a photo of the birthday candles.

It does but the opposite spin.. telling him there is party at a hall explains him thinking it could fit his family.

Don't encourage a child to do this

Why?

Gossipisgood · 28/09/2026 13:07

Don't cancel the party coz her Dad's being a tool. Tell him the time the party ends & that he can collect her from the venue so she can then spend time with him & his family afterwards. To sweeten it a bit offer to buy an extra Birthday cake for her to take with her for them all to share. If he moans about it tell him it's all booked & arranged just as your DD wanted it & you won't be going against what she wants as it's her Birthday so her choice.

Foodwench66 · 28/09/2026 14:48

I'd try and reschedule it for your custody weekend.

YouBelongHere · 28/09/2026 16:37

Not exactly helpful to your situation but the rigid 'well it's HIS weekend' is so annoying - what about the fact it's DD's birthday and she should be able to choose who and how she spends it? Unmoving 'well it's my weekend' contact arrangements are never in the best interest of the child but of the adult.

And also you did ask in advance? So I don't know why everyone is so stuck on it.

Going forward I'd just make sure he doesn't have all the details so he can't bring his entourage. I think him wanting to show his face is one thing, maybe even the grandparents is one thing, but he must know he's taking the piss by basically demanding all these extra people come rather than actually asking.

Maybe it's the cynic in me because my own Dad was useless but does he want to go so that he doesn't have to do a separate thing with her afterwards because 'oh you already had a party'?

fuckeditupbadly · 28/09/2026 17:25

I absolutely agree. This thread has been dominated by comments about 'his weekend' but the info very early on from the op explains why this was the case and that the dad was fine with it. Its irrelevant. The dd wanted her party, not unreasonably, on her birthday..given that it actually fell on a weekend, seems a shame not too. Bottom line is, the dad has tried to muscle in with his girlfriend and kids (no doubt demonstrating what a committed family man he is) to a party he has gone to no trouble for and is bollocksing up his dds party to show the gf and his parents what a great guy he is. Id he ACTUALLY was, he'd turn up to help, pay half and make sure his dd had the party she wanted.

greenpolkadot55 · 29/09/2026 03:53

Stop thinking about how you can make him happy. He sounds idiotic.
DD says ' what is she meant to do with ' the GFs two kids..well nothing..just carry on having fun with her friends.Its those that she wants at the party after all.
And will there be enough chairs...food...party bags ?
You may decide to uninvite your exdh but he will probably turn up anyway.

Good point. Op can just get supplies for the invited people and if he turns up with extra people they can stand there...

Unexpectedlysinglemum · 29/09/2026 14:59

Why on earth did you plan it on his weekend. Just say no to his guests, say you’re hosting this event which he agreed to send the daughter to, and he can plan another event for his side of the family as this is dd wishes. Never ever again plan an event on his time it’s madness

fuckeditupbadly · 29/09/2026 19:13

Oh my god!!! How many times? Its not 'his weekend' its the dd's birthday weekend and he agreed. There is nothing in the OPs posts that suggests he would be acting any differently if it was 'her' weekend. He'd still want to bring hig gf, her kids and his parents.

If it was her weekend though there would be no need for him to be told or involved though. The only reason he knows about the party is because it's his weekend.
I don't think some people get how difficult the other parent can be in a relationship and while it sounds petty to be saying his weekend this is the reality for many families and may be court ordered.

fuckeditupbadly · 29/09/2026 19:37

I've lived this for ten years. I get it. In this particular scenario the issue is not whose weekend the party was on. That's not what is causing the problem, and actually decent co-parents would allow the other to attend...as the OP is in fact. Just not his extra 5 people.

I get it too @Moonnstarz- some ex partners are deliberately obtuse and can’t be reasoned with - and I also agree the OP made a big mistake booking the party on the dad’s weekend.
But it’s done now, and because he initially said okay to it, I think he’s obliged to go along with whatever his DD wants.

Kally64 · 01/10/2026 09:55

I’m wondering if his GF is interfering here and saying her children should be invited. Stand your ground and tell him he was fine to start with, explain how upset your DD is, or maybe the three of you get together and let her explain. At the end of the day it’s her party but don’t let her rule the roost, she’s a child and has to begin to understand that life can be difficult sometimes. Hope you don’t cancel and have a great party 😁
