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?

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.

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.

TwinklyAmberSloth · 25/09/2026 16:03

@SynthWaveX YABU. It's his weekend so if you've used time on his weekend to organise a party, you should have known that he would want to be there and bring others.

If it had been your weekend then you would have been under no obligation to invite him.

Very poor planning on your behalf.

Why doesn't he come with his parents but not his GF and her children, as that would be fair.

HappyMeal564 · 25/09/2026 16:05

Will your parents and partner be there? If yes, that makes it trickier for you to say just dad comes. I know I'd want to be at my child's party

we’ve had gps come along, they stand back and watch the fun, it’s not that big a deal!

Did you also have the new gf and her kids and it be part of a 10 yo's birthday party who just wanted her friends there?

Having adults come along to watch makes it sound like a zoo exhibit.

It's their daughters birthday, his weekend/her weekend goes out the window.
If the daughter wants a party on a certain day with her friends then BOTH parents should be cool with this, it's not about their relationship or their other partner/parents/step children it is about the daughter...
Any decent parent would respect this!

But that poster said the dad shouldn’t be there. Understand not inviting all the extended relatives but a bit tricky saying dad shouldn’t be there for his DD’s birthday party on his weekend.

SynthWaveX · 25/09/2026 16:08

My mum will be there because she’s helping me with the food/cake etc, but DP probably won’t be there for the actual party because he’ll be working that night. So I can see why he thinks it’s unfair if my mum is there and his parents aren’t, but it was never meant to be a family party, I just need an extra adult there to help.

I do understand why he wants to be there, I really do. If it was just him I wouldn’t have an issue at all. It’s the suddenly bringing his GF, her 2 children and his parents as well when the whole thing was planned as a small drop off party that I’m struggling with.

Why did you book it on his weekend?

Perhaps her daughter wanted her party on that day and hasn't grasped what a twat her Dad is yet?

Newyearawaits · 25/09/2026 16:09

Wannabemornighmum · 25/09/2026 15:47

Ps his parents are her GPs too and he’s her dad, he has every right to want to be part of a birthday, roles reversed and people would be going nuts!!

100pc agree with this

GrantMyWishes · 25/09/2026 16:10

OP, do you still have any contact with his parents? If so, could you perhaps talk to his Mum, would she understand if you were to explain it all from your DD's perspective, and ask her to have a word with him, and tell him not to spoil the party just because HE wants to be involved. Or better still, do you think your daughter would be able to speak to her Granny and ask her to tell her Dad that she doesn't want anyone but her friends at her party, and while she wants to see the other people that he wants to bring, she would rather do it afterwards so that she can give them her full attention. Just a thought.

Don't encourage a child to do this

SoThatsTheWayItIs · 25/09/2026 16:11

Tell him he can come alone but not the extra people. Tell him if that is an issue he won't be invited to any future parties and then make sure not to arrange any on his weekend in future. Point out that currently his daughter would rather cancel than go along with his plans so he needs to stop being selfish.

Happyjoe · 25/09/2026 16:11

Don't cancel, go ahead as planned. Why should your daughter miss out because of her parents/dad? If he agreed with the plan originally, he shouldn't then change what's happening.

Does he know where the party is being held? Anyway, no, be firm. He and his family are not invited, they can do their own thing later in the day as originally planned.

They can see her after the party, on her birthday and celebrate with her. They don’t need to be at the party.

I think she is actually starting to figure it out - 10 is about the right age for that

ChestnutSquash · 25/09/2026 15:41

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

This is what I’d do in future, especially because it isn’t the first time he’s done this. It was kind of you to invite him (although I think it was a mistake to do it on his weekend even if he agreed and it was the nearest weekend date, he’s clearly a bit of a piss-taker sometimes)

He clearly doesn’t want the effort and expense of organizing it himself. You aren’t stopping his parents or partner and her kids seeing her. They can do something in the evening or organize a nice birthday treat for the day before/afterwards.

Amorica · 25/09/2026 16:15

He sounds like a bit of a nightmare since he agreed to it in advance and now wants to dictate.

If telling him he isn't invited will work YANBU to do so but will it?

Such bollocks. Grandparents never came to parties they had with their schoolmates any more than they do parties they go to now as adults. We had separate family birthday teas.

You're separate families now, he can't expect to attend events that you've paid for. Fair enough if you agree for him to come but for him to add on additional guests is unacceptable.

Tell him that you have max occupancy and that he can't come. He didn't say you could only have dd that weekend if you invite his other guests.

Is he likely to say you can't have dd that weekend anymore?

Bananacrepewithnuts · 25/09/2026 16:25

The mistake was booking it on this weekend. You shouldn't have done that.
Can you cancel and move ?

It's his weekend so I can see where he's coming from. The party eats into his time.
As you've booked it on the wrong day I honestly think you've got to suck it up and let him invite who he wants.

Yes it's going to be cramped but if it's really tight for space hopefully the relatives will take the hint and see there isn't really room for them and leave her to enjoy the party with her friends.

Good luck with it all.

You should have booked it on your weekend. Can you change it?

Randomchat · 25/09/2026 16:27

Could you say that your mum can't (or won't) come so could he come and be your helper? But there won't be space for any other extra people.

Then both her parents are there on equal terms with no extras. He still gets his party afterwards.

I realise he's not going to be as much of a help as your mum, and your mum might be disappointed.

Absolutely, sorry, I didn't mean to be arsey @SynthWaveX - it was more in your op, it looked like you had discussed this with the ex, and I just wanted to be clear what he had agreed...

U53rName · 25/09/2026 16:32

Nope. And only cater for the 11–food, drinks, 11 paper plates & paper napkins, 11 plastic cups. Tell him it’s a Y5 party that you’re funding, and you will only be catering for the 11 Y5 guests.

Would he be bringing an entourage if the party was pizza and a sleepover?

AnneLovesGilbert · 25/09/2026 16:32

How small is this hall where 14 children and a handful of adults puts you over capacity?

If you wanted to dictate who attends you’ve muddied the waters by doing it on his weekend, as others have said. Of course he wants to be involved (he should also be paying half) and his parents and partner to attend. It’s very rude to say he can pick her up once it’s finished.

By all means cancel or reschedule but you’ll probably lose the money so why not flexible and include the grandparents and partner?

SplishSplash123 · 25/09/2026 16:33

Tell him the party is just for DDs friends. He doesnt need to know your mum is coming. He can organise something else for his own side of the family and GFs kids.

But really, you have messed up a bit by organising something on "his" weekend when you know he's like this. Don't leave things open to these issues in future.
