AIBU to be confused by sibling invite?

I have somehow managed to get my child to 10 without having to hold a birthday party (born at Easter so we always go on hol instead!) so next week we are having our first party. It's at the house, small scale, drop off and go as the kids are all old enough. We invited 6 kids from school and out of this, 2 have asked if siblings can join and my mind is blown! Is this normal?

For context, one of these asked siblings is 3 years older, the other 3 years younger! My daughter doesn't know or play with them. They will be strangers at the party to everyone except their sibling, who will then be forced to stick to them. The party girl won't be as comfortable when 2 out of the 8 guests she doesn't know and didn't invite. I now have to not only buy more stuff, but also think about whether the activities I had planned cater for these new kids who I do not know. And if you're wondering why I said yes, I was kind of blindsided and it was put to me as if this was the done thing. Which having spoken to some other friends about this, it does indeed seem to be normal!

This has blown my mind. Never when I was younger would I have thought to be invited to my sisters parties. And as a parent, what goes through the mind when you ask? I know your other child is the most important person in the world to their sibling, but they mean nothing to the rest of the friend group - and if they did, they'd have got an invite! Am I out of touch on this and do I need to change my attitude? I'm doing my best to accommodate them and hope they have fun, before anyone thinks I'm a terrible grouch! I just feel like Lucky's Dad when he realised the rules of Pass the Parcel have changed since he was a kid 😂

I have a 13 and 10 year old. There is absolutely no way in this world the 13 year old would go to a 10 year olds party. Are the parents planning on staying or dropping a the teenager off aswell?

Violetparis · 04/04/2026 18:30

It's cheeky behaviour from the parents and I would have had no problem saying no to them.

Juswannaget · 04/04/2026 18:30

I have three children who all had birthday parties and siblings never came to the parties unless it was a toddler party involving family friends. It was totally unheard of for parties with the older age group . I think it’s very rude to ask and I would definitely have said NO .

Tramone · 04/04/2026 18:29

It’s not normal at those ages.

Out of interest, has your son been to others’ birthday events over his ten years, whilst you have never hosted?

Wtafdidido · 04/04/2026 18:26

Always put on the invitation “sorry we are unable to accommodate siblings in this occasion” and if anyone asks just say “No unfortunately we are unable to accommodate siblings “ No explanation needed. It’s cheeky fuckery for parents to expect siblings who have not been invited to attend. You’re not a babysitter.

ExplodingCarrots · 04/04/2026 18:24

You say more the merrier but my DD at 10 would have been fuming if I’d agreed to a 7 year old sibling she didn’t know to come to her party. She’s now nearly 13 and definitely wouldn’t want to go to a 10 year olds birthday party. It completely changes the dynamics. The parents are absolutely mugging you off and using you for childcare so they can have a child free afternoon . I’ve never experienced this for a party at home .

The more the merrier, I don't mind! Just baffled as it was 1/3 of the invited guests that asked and something I'd never come across before

But if it was more the merrier you would have invited more of your child's friends.
It seems weird that a 13 year old wants to come to a child's party. There is a good chance these extras will ruin things.

amber763 · 04/04/2026 18:22

It's weird.

MyLimeGuide · 04/04/2026 18:21

Don't say yes! How unbelievably rude of those parents!

MeatyMagda · 04/04/2026 18:20

It’s definitely not normal to ask if your 13 year old can come!! My 13 year old couldn’t be dragged to a primary school party at a strangers house - how odd and rude of them!

More fool you for saying yes.

I'm with @Caterina99 I think there is a difference when it is a small party at someone's home so they have clearly catered for that number & don't necessarily have the room / man to man marking capability to look out for 2 extra of quite dissimilar ages - in that case I think it's OK to say , no not convenient. Even if you have said yes I think you could phone back and say "On reflection I'm not sure how this will work - sorry "

Watchoutfortheslowaraf · 04/04/2026 18:18

Why have you said yes if the answer is no?

Revrin · 04/04/2026 18:15

some parents dump siblings at parties. It pisses people off. One party I did, I specifically said we couldn’t accommodate siblings. One mum still dumped two siblings and ran off. DD was not happy as she would have rather had two more friends but numbers were limited.

Caterina99 · 04/04/2026 18:09

I think that’s really weird for a 10 year old.

5 year olds, toddlers, soft play etc, I totally get it and can see why people ask. But a house party for a few friends at age 10? Why on earth would a 13 year old want to go? And a 7 year old is a big difference too. Especially if these kids aren’t great friends with your kid!

My kids are 8 and 10 and I’d never dream of asking if one could go along to another ones party at a friends house. Except maybe if it was a very close family friend or I had some kind of childcare emergency!

RealEagle · 04/04/2026 18:08

More fool you for saying yes.

YourHeartyFatball · 04/04/2026 18:07

Can my kids come? I’ve only got 3. 😂

GTTSR · 04/04/2026 18:03

My mind is blown along with yours OP. Go back and say no…it’s a small party and if you go ahead effectively 1/4 of the guests will be unknown to you and the birthday girl. You’d rather invite other friends of your child but couldn’t because space so it’s not appropriate. Cheeky fuckery of the highest order!

Moonnstarz · 04/04/2026 18:02

YABU for not saying no. I would message them back and say that there isn't room for siblings.
Is this a weekday and they are looking for a cheap activity for all children or free childcare during the holidays?
My daughter is 10 and I would never say could her brother attend a party, especially one at home. No parent stays at this age so there is no reason a sibling needs to come too.

PearLover4 · 04/04/2026 18:02

ColdAsAWitches · 04/04/2026 17:56

I mean, you're overreacting by having your mind blown. What's the harm in them asking? Just say, no sorry it's just a small party for her immediate friends.

My mind is blown because I'm just baffled as to when this became a thing and why! If I got invited to a work mates wedding, I wouldn't think to ask if my best mate can come to. This isn't done under any other circumstance is it, and it never used to be done and now it's clearly the done thing, so sorry lol but I am blown over by it. There is no harm in them asking - or coming! - I'm just baffled as to WHY they asked and why on earth they'd think their child that doesn't know the party girl would be included?

Just say if you are bringing siblings you need to stay.

whitehawthornblossom · 04/04/2026 18:00

Well, at our soft play there is a separate party room so siblings go up but don’t have food or a party bag. (But there generally is food left over; kids never seem to eat much at parties. I don’t know why as I love a party buffet!)

It does seem really odd but there sometimes are unwritten rules which vary place by place.

Longtimelurkerfinallyposts · 04/04/2026 17:59

You've got time to rescind the invitation.
Go back to the CF parents and say that you've now had a chance to speak with the birthday girl, and she would rather just have the small 6-person party that she originally asked for, in your not-massive house, so sorry, but the siblings will have to do something else that day.

PurpleEmerald · 04/04/2026 17:59

A 13 year old? Unless they are one of those kids who love younger siblings (then they might be helpful?) they will probably sit on their phone if you let them. A 7 year old is tricker…..

PearLover4 · 04/04/2026 17:59

whitehawthornblossom · 04/04/2026 17:49

Kind of. Soft play parties are the parties of choice round here and people take siblings but pay for them to enter the soft play.

I do think there’s a different ‘done thing’ ranging from school to school and possible even class to class. I mean I wouldn’t do it myself but I probably wouldn’t accept the invite for a home party either.

Haven't come across this but I get it! Mum is sitting in soft play so why don't take the other kids too. The whole soft play isn't booked out so they're just like other customers aren't they. Or would they expect to be sat at the birthday table, having cake and a party bag? Surely not!

Honestly I can't understand the reasoning behind it and I'm genuinely curious. Do people worry the uninvited children are missing out and will be sad? Is it a chance to get rid of all kids at once as childcare?
