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?

It's her birthday... tell him her wishes and that it isn't about who he wants or who you wants, it's her day and her wishes, explain its upsetting her and you will do as she wishes or HE is going to ruin her birthday... its as simple as that and he can't argue with that!!

Kids pick up on the negative vibes. I would smile, suck it up, encourage your daughter to be positive about it and just do the party. Next time do something different OR say to the ex, the venue has an issue with numbers, let’s book a bigger venue and he pays the extra cost. He will soon change his mind. He’s probably doing this so he doesn’t have to fork out himself.

All this “your weekend” and “his time” talk is just the pits.
It’s all the DDs time, and it’s the DDs birthday. She should be able to have a little party with her friends in her own time and on her own birthday without it becoming the Cuban mission crisis between her parents.
I’d be tempted to fake a cancellation to allow her to have the party she wants without the drama, but would she be worrying about him kicking off when he finds out, and would th worry spoil it for her anyway?

Who is going to be there to check on numbers, no one probably, just let dad and grandparents come but tell him your daughter has explicitly said she doesn’t want his girlfriend’s kids there. If dad doesn’t like it he can pick her up afterwards and they can do something with girlfriend and her kids then. In future communicate about these things begire to avoid this stuff happening. You shouldn’t dominate or have full control over her birthday, she’s her dad’s child also. Hope it all goes to plan.

There's no perfect solution to this. You'll have to do it on your time and not invite him. He can organise his own family event if that's what he wants. Can you move it to the Friday evening?

You have said that he has form for doing this type of thing. Try to remember this experience for next time and get ahead of it.

Not really, if she wants a small party with her friends there is no reason for a whole army of adults to make it cringe for her. The adults can have her right after the party, no?

In which case, no need for OP's parents to be there is there.

Op's mum can stay at home and her daughter's dad can have that spot, and rightly so, he is more important than OP's mum being there.

KLD89 · Yesterday 23:14

Have you told him DD doesn’t want him or her ‘step siblings’ there, respectfully? Does he know how upset she is, that she doesn’t even want the party anymore? I’d be saying “I know you’re her dad, but can you please just let her have her party with her friends without gate crashing. We’re her parents, we cramp her style, I’m sure she wouldn’t even want me there if there was an option. You can pick her up at the end and then you’ve got her all weekend to do whatever the hell you want, with whoever”

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.

It’s your party, you’e allowed to have your mum there!

Why do you think he has any sort of say here? You’re giving him too much power.

OP has organised and paid for this party. If she wants her mum there, she can have her mum there.

The plan was for her ex to have dd AFTER the party. He is the one going back on his word, not OP. Stop all this appeasement.

Bunny65 · Today 03:37

Your ex is being ridiculous. Tell him you’re only allowed specific numbers and DD just wants it with her friends. There’s no reason for him to drag his extended family along. He can have his own party with her. I also don’t think you should cancel at all.

changeme4this · Today 05:41

Where is this hall that only holds 13/14 people?

I can understand why your DD wants to cancel. She is 9 years old and her parents cannot agree to get along even for her birthday and it’s become a big issue about you two rather than her having a lovely couple of hours.

you have years ahead of having to share her with her DDad. Please learn to work something out where you share her special moments and give her a wonderful day !

A couple of pps have mentioned the improbably small hall, which I completely understand, but for reference, where I used to live in NW London there was a “hall” - more a very large room really - with a tiny kitchen attached, and a very small maximum capacity, that was often hired out for kids’ parties etc.

springvegetables · Today 06:37

Op you’ve learned a very valuable lesson here. Next time I’d DD wants a party on her actual birthday and it’s his weekend he can organise it, and if he insists on coming g perhaps he should pay half and help organise/ supervise the children
