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?

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.

Dogmum6 · Yesterday 18:53

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?

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.

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.

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.

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.

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.

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?

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?

Nevermind31 · Yesterday 19:44

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

Igmum · Yesterday 19:51

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

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.

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..

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!

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.

GetBernie · Yesterday 20:02

You should have booked it on a day that wasn't his weekend, especially if he has form for being difficult. You should have said yes to his parents coming (I seriously doubt a church/community hall place is so tight on numbers that they couldn't be fitted in) and said a hard no to his GF and her children, and put your foot down about that.

But then if you'd booked on your own time and not his, none of this would have been an issue.

DearCritic · Yesterday 20:06

We’ve been invited to a few children’s birthday parties twice 😬 happens sometimes when parents aren’t together. 🤷‍♀️ tell him he can arrange his own party for her… and next time… just arrange the party on your weekend.

WotsitsMadeIn1927 · Yesterday 20:10

Tell him you’ve cancelled it and doing lunch and shopping instead. Just have the party without telling him.

Databreach · Yesterday 20:33

My ten year old would be mortified to have little kids at their birthday party. He is being very unreasonable.

TwinklySquid · Yesterday 20:35

I would tell him that this has all got messy . For this party, because of the rules on numbers, just he could come along. Tell him had you known others wanted to come, you have booked a bigger venue but can’t now. Or could grandparents come to pick up? Maybe you do the cake just before everyone leaves so they can watch it? If they are only going to be there a few minutes for pick up, you can say the venue would have a hard time moaning at numbers as you’ll claim it’s just a pick up. Make the venue the “bad guy”.

Then say we should agree going forward. She’ll be in secondary school for the next birthday so if she wants a party, the extra adults would be a great so his parents/partner would be so handy. If she doesn’t want a party, tell him he can have her on her actual birthday (even if outside pre agreed dates) so he can plan a family get together.

I grew up with parents who couldn’t be in the same room as each other. It put me off loads of events. I’d have said the same as your daughter. Just leave it. The above gives a way for it to go ahead

Definitelynotagladiator · Yesterday 20:35

It’s a FRIENDS party for crying out loud! Paid and organised by mum.
Dad will literally see her straight afterwards and can have his party then. He can then invite anyone he wants to his house or wherever to celebrate his daughter. He’s an absolute knobjockey for shoehorning in relatives to his daughter’s FRIENDS party.
She will remember this for a long time and won’t forgive him.
I would tell him straight that if he turns up with ANYONE he will have ruined it for her and that is completely on him!

Bamboozle30001 · Yesterday 20:39

Is there a way to message the hire contact asking to confirm the numbers of people allowed at the venue. Then screenshot and sent to ex saying, see I'm not being difficult its a health and safety thing.

LalaPaloosa2024 · Yesterday 20:50

Do not even think about cancelling you daughter’s party. Tell your ex that he, his parents, his girlfriend and her children are not invited and will be asked to leave if they turn up. It sounds like he isn’t paying anything towards it. He’s not hosting and he doesn’t get to issue invitations to a party someone else has arranged and paid for. What a controlling bastard. You don’t need to make excuses for having your Mum there. It’s none of his business. He can arrange a separate celebration himself.

Going forward, only arrange parties on your weekends and don’t tell him about them. He sounds controlling and like he wants to dominate you. You need to cut him off for your own sake. Your daughter will have her own relationship with him. She’s getting older now and soon you won’t have to be involved with him very much at all.

You should have booked on your weekend and not told him. Can you cancel?

You really messed up why didn't book it for the weekend before or weekend after, if you cancel you will have to explain to all the children invited that there's no longer a party.

Northernlights19 · Yesterday 20:57

I don't get why the whole family needs to be at children's parties. My daughters dad had his parents, brothers, girlfriend, friends etc at hers. I found it strange tbh. I'd never take a new boyfriend/girlfriend anyway because it's unnecessary. And the party is for the child and their friends. It also probably made me look like the odd one out to the kids parents as I didn't feel the need to have an extra 8 adults around. My daughter didn't care about or really even notice which adults were there as she was off playing with her friends. Not everything needs to be a whole family event.

So I wouldn't cancel OP, but I'd be clear he's very welcome but there isn't space. If pushed I'd tell him it will upset your daughter because it's against your wishes. If pushed again I'd say if all the extra people turn up it will spoil it for your daughter and they won't be let in anyway due to the numbers. Hopefully all the other adults he wants to bring won't want to either be turned away or shut a 10yos party down when they can see her any other time.

Zerosleep · Yesterday 21:01

I don’t know why he is invited or needs to come, he can have his own party and celebration with her afterwards. Tell him he won’t be coming and he won’t be bringing anyone else either as it’s upsetting her. Take control back and stop letting him bully everyone.
