To ask that my nephews don’t come

My niece is going through the usual hardships that many teenagers go through at high school. So for her birthday I decided to organise a girls only afternoon tea, and I invited my mum, sister, and niece to come along with my own two daughters and my son (because I’m on mat leave with him).

However, it’s caused a major argument with my sister (whose daughter I planned the event to celebrate). She is annoyed that I didn’t include my two nephews in the invite. I said for my niece, I thought it would be nice to make it girls only and not have her brothers there now she’s older. Now my sister is saying that she’s not going to come and therefore won’t bring my niece either, unless I include my nephews. She also used as an argument that my 6 month old will be there and he’s a boy. Not sure this is of relevance but I’m paying for the event.

should I include my nephews or stand my groundy daughters are still young but I always intentionally do some special things for just them and me and plan to continue that so I didn’t think I would offend anyone by planning this.

Not sure how many people commenting on here are from big families themselves but growing up we didn’t always do things as a whole family the whole time so it’s completely normal for us an I’ve not grown into an adult who resents that my brothers got to do things I didn’t get to do.

So why can't you leave your children behind in that case so that it's adults only?

“meanwhile my mum and I are on a group chat with my sister trying to explain that it might help their relationship”

OMG why are you doing that?! I’ve never heard a dynamic like it.

Poptartz · 16/02/2026 20:20

I think you have hit a nerve for your sister. Perhaps because it’s her daughter’s 18th which is quite a milestone. Perhaps that’s why she wanted to invite the boys too. I don’t think you get to dictate who comes. That’s up to your niece. Particularly if you are bringing young children along you might as well all go. I think it’s a bit unfair to say you are closer to your niece than her mum. Teenagers swap and change their minds quite regularly about who they do/don’t like.

It's not really a nice girls afternoon tea with 3 under 5s. Taking your DC turns it into a family event for your nieces 18th, excluding her brothers.

Littlebitofthis1 · 16/02/2026 20:17

@JingsMahBucket thanks, yes we’re currently trying to figure out the way forward. My niece doesn’t know any of this is going on in the background, and meanwhile my mum and I are on a group chat with my sister trying to explain that it might help their relationship.

in all likelihood because I don’t want to cancel the whole thing, I’ll end up caving to let my nephews come. It always transpires this way and in the past they’ve even told me they were forced by their mum but didn’t want to be there

@SweeetFannyAdams ive said it’s not that deep. I didn’t plan anything for months on end and then spring it on my sister like BAM. I messaged my niece to say would she fancy a girls only afternoon tea but I’d have to bring the kids with me. She said yes, so I then called to tell my sister I was going to book it and that’s when we’ve fallen out.

So your niece is 18? Your sister can’t stop her attending. Message your sister “I would love you to come but if you can’t make it I’m very happy to still take niece as this was her treat really”

BreadstickBurglar · 16/02/2026 20:15

As an aside how absolutely infuriating for the niece that all weekend events are family events. Doesn’t she ever get to see friends or go out with just her mum/dad to the cinema etc?

BreadstickBurglar · 16/02/2026 20:13

yes she’s getting a treat - because it’s her birthday!

If you want to have a girls only afternoon tea and you’re the organiser why the hell not. But since your sister is being like this I think you’ve got two options.

  1. Just make it you and your niece, she cannot object to that or insist you invite everyone

  2. Do the girly tea but detach it from your niece’s birthday

JemimaTiggywinkles · 16/02/2026 20:07

Yeah, your updates have convinced me you aren’t actually looking for advice. You just want approval for using your niece’s birthday as an attempt to be cool aunt in opposition to the evil mother. So I’m out.

I agree.

OP talks to sister every day but forgets to mention organising an afternoon tea for nieces 18th.
The afternoon tea is suitable for little children but not teenage boys.
There is already a strained relationship between a mum and daughter.

If this was a genuine gift out of kindness for the niece it would be the two of them going for it, or as it turns out the niece is 18, then an adults outing only and no teenage boys or little children would be included.

I am not sure why the male relatives can't look after the little kids but I am sure there will be some justification (I think it has already been mentioned how much the niece loves her little cousins).

AlwaysTheRenegade · 16/02/2026 20:13

You sound like a lovely Aunty! Both of my aunt's have done things like this for me my whole life! I'm really lucky. I'm 36 and we still enjoy spending time together and I've got lovely memories.
Your sister's being a dick.

JingsMahBucket · 16/02/2026 20:13

@Littlebitofthis1 ignoring the couple of weird posters who are trying to twist your words. They’re not worth your energy and are just being argumentative goady fuckers.

Regarding your niece, is it possible for you or your mum to just collect her and take her to the afternoon tea? Since she’s 18, everyone can just bypass your sister now.

SweeetFannyAdams · 16/02/2026 20:10

Did you read the plot twist though?

It turns out her daughter is an adult.

I know! Just updated.

tinyspiny · 16/02/2026 20:11

It sounds like your niece has it spot on that her mum prefers her brothers . Just take your niece out with your mum and her own mother can miss out , at 18 she doesn’t need her mums permission to go out .

Driftingawaynow · 16/02/2026 20:11

So you’re excluding them just because they are boys? Why? Just seems so small minded and provincial.

SweeetFannyAdams · 16/02/2026 20:10

Supporting2026 · 16/02/2026 20:08

It wasn't an unreasonable plan - but you are super unreasonable to suggest "standing your ground" against the wishes of your niece's mother. In the end its her call what her own daughter does and encouraging friction between them is not ok. [EDIT - just saw niece is turning 18 - so its a bit different - but if she needs her mother to bring her then its not her call, its her mother's. My comment on it not being ok to encourage friction between them also still stands.]

Why are you forcing girls only? I dont get this girl obsession, but for someone's birthday i would ask and do what they wanted not what I had planned

I used to hate it when mil would invite dd1 to things and leave out dd2&3.

SweeetFannyAdams · 16/02/2026 20:06

Littlebitofthis1 · 16/02/2026 20:02

@SweeetFannyAdams ngl, I think this is projecting now.

And 'ngl' either, you're still not telling us why you planned this behind your sister's back.

You speak to her every single day and yet you 'forgot'?

Either way, as you've eventually told us your niece is an adult, she doesn't need her mother's permission to go anyway.

Just pick her up yourself and have a good time.

Ophy83 · 16/02/2026 20:05

Just tell your sister she doesn't have to come. Niece is an adult and can choose to come without her brothers

Littlebitofthis1 · 16/02/2026 20:05

@JemimaTiggywinkles HAHAHA I take it as a compliment. If literally arranging an event which actually gives my sister an opportunity to show her own daughter that she will attend something with her, without bringing along her brothers makes me a witch then I’m here for it 💅

I also feel like at 18 my relationship with my niece can be separate to my relationship with my sister to a certain extent

Then just invite your niece. Don't invite 2 adults, all of your kids but only one of your sister's kids.
