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?

Set up a family table?
Are you having a laugh?

Are you suggesting that the OP as well as organising and paying for a party the DD specifically wanted should now at the last minute organise, shop, prepare and pay for food and entertainment for six more people?

Its a party for 10 schoolgirls aged 10 with an age-related activity paid for per person in a very small venue. Parents are dropping off and picking up.

The Dad agreed that DD could have the party on his weekend. ( and a party is only 2 hours) He was only supposed to collect her af the end.

Now he wants to bring six people and cash in on the whole event. Why can't he organise his own event for DD?

The DD doesn't want her dad to bring relatives and his GF's children to her party with her classmates. She doesn't want this so much she is talking about cancelling.

He's got the DD for the rest of the weekend afterwards with his parents, GF and her two young children who are too young for the activity..

Presume the food is sandwiches and entertainment already happening so the suggestion of a family table was simply so the younger children and other family members were seated away from party girl’s friends! Is very normal to have a few adults and hanger on younger children at parties.

andfinallyhereweare · Yesterday 19:55

@SynthWaveX i wouldn’t let your DD cancel what is that teaching her that when it feels hard to stand up for yourself you just give up and don’t do what you want. Her needs and wants are important this is what she wants to do and you have spent money on it. Don’t let her turn into someone who doesn’t do what she wants to do as it feels too hard, sometimes standing up for what we want is hard, but worth it!

Sorry I think yabu and am with your dp. It is his weekend and it is her birthday and he wants to bring a few family members along. I appreciate that will change the dynamic a bit but so be it. Maybe set up a family table for the eating part. If your dd doesn’t now want this party you just have to cancel it or try to move it to your weekend.

So sorry you're going through this Synth, he's an absolute knob, thank heavens you are no longer together.

Simple solution, he isn't invited. You organised the party. He is welcome to organise his own party for her and include all the people he wants to - then maybe he will actually pay attention to his daughter.

Good luck

Nevermind31 · Yesterday 19:44

Is he contributing to the party? If not, he doesn’t get to invite others.

I would say dad and grandparents are ok but. the GF and kids as the def puts numbers over . I think it's tough to say no grandparents. It's nice they want to be there no?

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?

He can like things being big family occasions, that’s just a different opinion to you! I agree it’s his weekend you’re going to have to give leeway, none of it is that big a deal, the less drama the better on her birthday

The point is that the birthday girl doesn't want it to be a big family occasion. Don't her wishes count?

pollymere · Yesterday 19:11

As the girlfriend, I'd be mortified to turn up to a party where I'm clearly not invited. What line has he spun her that she thinks your DD is okay with two small children going?!

You can't have two more children there because it would mean thirteen at the table for a start and many people are superstitious about that. Also, he's a fool if he thinks adding six extra guests — half again — won't make any difference. I'm wondering if asking for money to cover the cost of the extra guests would scare him off? My DC have had parties where the cake is designed to feed 12, and I've bought 12 plates, cups etc. I had someone try to leave a sibling and I pointed out there wasn't a seat, or crockery for them, and not enough food. Has your Ex considered that? There is also the huge age gap. The GFs kids will be ignored and bored very quickly (this could work in your favour anyway).

Unfortunately I think you may need to stand firm and tell him to stop gaslighting. You've made it very clear that DD would rather cancel and he's heartless if he pushes her into something that makes her miserable. He needs to stop being selfish and make the day about DD unless he wants her to terminate her relationship with him completely when she's older because she hates him. There isn't room or funds to accommodate extra guests anyway and if they turn up, it's going to create huge issues and embarrass Ex and his parents. Reassure DD she will have the party she wants and point out how silly it will be if they do try to come.

MatronPomfrey · Yesterday 19:09

Have the party that you have arranged and paid for. Tell him he’s not invited because he can’t be trusted not to bring others. He can then pick her up and arrange whatever get together he wants with his family. You do not have to make him happy. In the future, only make plans for your weekends and limit the information you give him. It’s a nice idea that her Dad could attend the party but not if he thinks he can invite others. As for not seeing her grandparents recently, that’s on him.

Jimmyjumpy · Yesterday 19:04

I dont think it unreasonable that he wants to be there but say no way to anymore. If you know his parents well then better still tell them yourself.

Brainstorm23 · Yesterday 19:01

Honestly your ex is an absolute idiot. How he can't put pettiness aside for a day for the sake of his daughter is beyond me. I'm divorced and manage to do parties for my daughter with my ex with no drama. The idea of bringing parents, girlfriend (and her kids) is ridiculous. They can all do something nice afterwards and the next day.

Sassylovesbooks · Yesterday 18:57

Your ex has basically moved the goal posts. Originally he was happy for your daughter to have her birthday party on his weekend, and see her after the party had finished. He's now changed his mind and probably views that he has a right to attend (with extra guests), because he's her Dad and it's his weekend.

You have several choices here: 1) cancel the party and rearrange it on your weekend. 2) the party goes ahead but you tell your ex that due to the capacity of the venue and fire regulations only he can attend. 3) tell your ex that due to the capacity and fire regulations, he can't come and will have to see your daughter after the party as arranged. 4) conceded completely and allow your ex and his extras to attend.

Going forward, don't ever arrange a party or an event on your ex's weekend. He's likely to backtrack on any agreement made and make life difficult. I appreciate you were following your daughter's wishes, as it was her, who wanted the party on her actual birthday, which happened to fall on her Dad's weekend. Your ex is incapable of putting his daughter's wishes ahead of his own, and this situation proves it.

I sm separated from my husband for years word of advice if it is not your weekend when it is your child birthday do not organise anything that weekend do it the weekend before or after.

crazymommaclub · Yesterday 18:47

I would suggest you keep the party as originally planned. Then he can hire the hall afterwards for another couple of hours, so when her friends leave his family can come celebrate with her

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.

Swap your mum for him. No other adults there. No invited children. If he cares about your DD, he will put her first then arrange a dinner with his family and new partner afterwards. You get the help. Daughter gets her party. He doesn't have time taken away. You don't lose money. Win. Win. Win

GabriellaFaith · Yesterday 18:38

I expect most people could rearenage to another weekend for the party, do that

MILLYmo0se · Yesterday 18:28

SynthWaveX · 25/09/2026 15:47

Because we have always swapped weekends around for birthdays and things, it didn’t really occur to me that it would be a problem. Her birthday is next Saturday and that was the only date the hall had that worked for us, plus it was the date DD wanted because of the school friends she invited. I did tell him before I booked it and he said that was fine, which is why I’m a bit taken aback by it all now. I wasn’t just booking it behind his back and then telling him he couldn’t see her.

But when you booked it dud you tell him he and his family weren't allowed to come? Or just 'is it ok if I go ahead and organise the party to be on the day you have her?' If the latter then he was just saying its fine for the party yo take place that weekend, probably never occurred to anyone that they werent welcome unless you spelled that out

Delphiniumandlupins · Yesterday 18:25

Go ahead with the party. Would it be an option to have your ex helping in the kitchen instead of your mum? Or his mum? Tell him there isn't space for 6 extra people and it will change the party your DD wants and has planned. Why doesn't he plan a celebration with her which can include his parents, his GF and her children? Your DD can have a second cake with candles and enjoy her presents from his family, without being distracted by her school friends.

GoneAlready · Yesterday 18:21

Have you made it very clear to him that this isn’t just about the numbers at the venue, that it’s actually DD who doesn’t want the additional guests - to the point that she’s now saying she doesn’t even want the party any more?

Would it make a difference to him if he knew this was coming from her, rather than you trying to “thwart” his plans with his family, as he may see it?

Fasthorses · Yesterday 18:17

No community hall i know of has a capacity under 25-30 people, i find it hard to believe you cant manage to fit her grandparents on his dads side in.
His gf and her children are a different matter and if DD doesnt want them there, they cant come.

But his parent's, DD's grandparents - you are not being reasonable saying they can't come. Its very very normal at a church /community hall party of this type for a few grandparents /aunties and cousins etc to join in.

I bet your mum is coming.

And you should never have booked it for his weekend - im guessing you wanted to spend your daughters birthday with her but it was her dads weekend so booking her party for that weekend was your way of ensuring you had your dd yourself that weekend.

Her dad is just as important a parent as you are.

Trallers · Yesterday 18:15

I'd say he comes as you food helper and all other adults don't come. Horrible to be backed into a corner like that by him.

Lainie · Yesterday 18:04

e mail and ask the manager if you are allowed 5 extra, they will reply no because of the insurance reasons, then copy the e mails to ex hubby and its proof you tried

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!

That is quite an escalation. Does a ten year old really want to remember bouncers refusing her granny entrance to her birthday party?

The dad is an arse - he has his own celebration to invite his family and girlfriend to. He isn’t paying for the party but is planning to add to the numbers by four adults and two children.

OP hasnt threatened to bring her family to his celebrations - but it would hurt for him and the grandparents to pop their heads into the party and say happy birthday. Would be odd at that age to have that many adults watching ten ten year old girls.

Lizchapman · Yesterday 18:00

Just go ahead with the party as you planned it and to which he originally agreed. He’s having time with her afterwards and can invite everyone else to that.
