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?

pay for security, cheaper than cancelling it all.

This is exactly what I was about to comment. No invite, no entry. If Dad wants to make a big deal out of it and upset his daughter, this is what he should turn up to!

LittlePaintBox · Yesterday 17:52

I think it's unreasonable of whoever let your DD know that there's an argument about her party. This is so difficult for her that she'd rather do without the party. I'm afraid this might be a situation where you need to be quite forceful and insist on the boundaries that you've set.

I'm puzzled about the limit on numbers - if it's to with fire regs, you certainly shouldn't go over the specified number, and you should tell your husband that.

I hope you can sort it out so your DD gets the party she would like.

Oh your poor daughter
10 is a HUGE deal for children. My 9 year old granddaughter is so excited to reach her double digit era and I as a responsible nanny have bought literally every item of stuff. For your daughter to say she would rather cancel it she must be going through some emotions we have no rights to put our children through and you gotta tell her father exactly what she has said. He is having her straight after party so thats his time to share with his side of the family. I wish you luck with this. 😍

I think people have twisted what visitation is actually supposed to be
Visitation is supposed to be for the benefit of the child to spend equal time with their parents
When you call it his week and her week it makes it all about what the parent wants and not the child

Sod off with your visitation crap. What a crock of shit.

Why would you bother to comment on a situation you don't have the facts about? She's explained repeatedly why it was booked on the birthday weekend and that he was fine about it.

whats to be complaining about then. She got what she wanted. She can't control how other people think.

Allowing the birthday girl’s grandma and not dad’s girlfriend and her kids is a WILD comparison to make when trying to say the op is unreasonable.

OP is refusing grandparent from dad's side but allowing her own.

OP has indicated her partner would be welcome but because he's on nights probably won't bother but the dads partner isn't welcome

I was just pointing out that it could be seen as controlling too.

LizandDerekGoals · Yesterday 13:32

BlueMum16 · Yesterday 10:14

Or maybe the OP is just the controlling one?

Booking something on his day and dictating who can and cannot go. Allowing her extended family but not his?

They are both the DD parents. If it's amicable enough to ask to use his time it's amicable enough to parent together

But the point still stands it was his weekend, so if not amicable there was always the risk he would do something like this last minute.

For some people you need to stick to the rules in place, however annoying they might be. As I said the DD is turning 10 so it all could have been explained easily by mum to avoid this conflict - 'your birthday falls on dad's weekend, he might want to do something with you. We can do your party with friends on my weekend or one night after school, or you can ask your dad to arrange your party if you insist it must be on your birthday.'

I would explain to your ex and ex in laws that you would have happily had them there but that DD wants just her friends there and that she's getting upset with the requests to change the set up. That should calm them down. Remind them that that is what your DD wants.

Reiterate that they can then take her to do something special and celebrate with her after her party....but her party should be set up how she wants. Good luck. It sounds really stressful xx

CaramelGhost · Yesterday 10:37

Op don't overthink it. Let him crack on and come if he wants to. It isn't your DDs job to entertain his girlfriends kids. Going forward, book it on your weekend and say nothing. It'll probably be the last kiddie party she had anyway, just smile and go with it

Bellyblueboy · Yesterday 10:30

i Would send him this -

Dave, I had planned Jane’s party to be just for her school friends. I thought we were doing our own separate things, I planned and paid for her party and you planned and paid for something for your family later in the day. You are welcome to drop into her party, as are your mum and dad, but there won’t be room for your girlfriend or her two children. The kids are really far too young for a ten year old birthday party and Jane doesn’t want much younger children there, even if there was space. Please respect our wishes on this. I have no intention of attending your birthday celebrations, or brining additional guests along to whatever you have planned. Thanks

Can you afford a bouncer? 😅 Or a strong female friend to help you with setting up instead of your mum...

comealongdobbeh · Yesterday 09:11

You’ve booked it. Youve arranged and i assume you’re paying for it.

why is he even invited???

tell him to arrange his own party and give your daughter the party she wants and deserves.

LizandDerekGoals · Yesterday 09:05

SynthWaveX · 25/09/2026 16:55

I have tried telling him that DD is now saying she doesn’t want the party at all and it hasn’t really made a difference. He says she is upset because I’ve made it into an argument and that she’ll be fine once the day comes. Which I suppose is possible, but I don’t really want to take that chance.

I could maybe rearrange it but DD really wants it on her actual birthday and that was the date she chose. I also can’t afford to just book another hall and entertainer and lose what I’ve already paid, so I’m reluctant to do that unless I absolutely have to.

I hadn’t thought about getting someone else to help instead of my mum. She is only there because I need another adult for the practical stuff, not because I’ve invited her as a guest. But I can see why he might use that as an argument if she’s there and his parents aren’t. I might ask my mum if she’d be willing to stay away and get a friend to help instead, although I’m not sure that will actually make him happy tbh.

DP thinks I should just stop negotiating with him and have the party as planned
agreed.

and if he doesn’t want to come then that’s his choice
absofuckinglutely. He didnt arrange a party, did he!

My mum thinks cancelling would be unfair on DD because she shouldn’t lose her party
exactly.

just because her parents can’t agree
that isnt the reason. It is because her father wants his own way, despite his dd not wanting that and despite it being impractical.

I’m also annoyed because I’ve saved for this and already paid for everything, so cancelling it feels ridiculous
did you ask him for half? Im not suggesting you do as he would then expect control. But maybe next year you tell him he arranges the party (but also plan something and dont tell him)

I’m now thinking I should just tell him he isn’t invited if he is bringing everyone else
this. He picks her up at the arranged time. If he wants a party to include his family, he arranges one. If his parents have not seen her in a while, who does he think is to blame? That is on him and them.

keep the party exactly as planned and let him have DD afterwards

this and atop telling dd about his mantrum. It is upsetting her.

But then I worry she’ll feel like I deliberately excluded her dad from her birthday.
she does not want him and his new family there.

Moonnstarz · Yesterday 09:00

Bluffinwithmymuffin · Yesterday 08:00

If it’s not amicable between the OP and the dad, then all the more reason to tell him straight not to come; he can have his time with Dd afterwards, without spoiling the party.
We don’t know the OP or anyone involved though, so we can’t reasonably say (or doubt) what she would’ve done if the situation was reversed.

But the point still stands it was his weekend, so if not amicable there was always the risk he would do something like this last minute.

To all those saying he agreed, yes he did, but surely he assumed he would be included in a birthday party on his weekend on his daughter's actual birthday.

Nanaboots · Yesterday 08:57

Just tell him the hall isn’t big enough, show him the paperwork from the hall and the guest list there isn’t room and that’s that.

i would also point out that if his parents and girlfriend etc expect to attend the party you are doing for her, then you your partner and parents will be gatecrashing his party

LogicVoid · Yesterday 08:52

I guess he is paying half towards the party costs..? No, didn't think so. He's piggy-backing on your time, energy, and £s. If he wants to be involved and share the experience as a parent, then he needs to have planned and participated properly, not agreed to the original arrangement and then hijacked at the last minute.
