AIBU to refuse looking after my sister's child during her honeymoon?

My sister is getting married in just over 2 weeks. I have helped her to organise her wedding and looked after her child when she has been to appointments and had wedding things to sort out. It’s a big wedding, she’s found it all quite stressful so I have done what I can to help.

I have booked 2 weeks off after her wedding because I feel like I need the rest after all the stress and I have leave to use. My husband and I are going away for 2 nights but we plan to chill out at home, get some things done around the house, go out for meals, have an evening at the theatre and just spend some time together.

My sister wasn’t planning on a honeymoon but her in-laws have just gifted them 2 weeks at their holiday home. Her partner was aware but it was a surprise to my sister until over the weekend when they told her.

We presumed they would take their child with them but yesterday they asked if we would have her when they’re away so they get a proper honeymoon. I must have looked horrified as my sister said maybe in-laws could have her for one week so could we just have her for one week.

I have said no as my husband and I also want to spend time together. My sisters child is 8 and although she is lovely, we’ll have to entertain her. Our children are older so don’t require looking after and we have had a stressful few months with GCSEs and the wedding prep. We just want to relax. My husband has also said absolutely no way.

My sisters in laws have contacted me to say that we can sort this between us and let my sister and new husband have a lovely honeymoon.

Are we being unreasonable?

My sister offered to look after my 9 year old DS so I could go in honeymoon. I'd have done the same for her. Your sisters child is your dear niece. It wouldn't hurt you to put yourself out for 1 week of your 2 week holiday.

OP had her children before her sister had hers and her sister never helped her with a single day of childcare. OP looked after her niece once a week before her niece started school and has done lots of babysitting for her sister. Her sister is the selfish one, not OP.

IDrinkTeaAllTheTime · 15/07/2026 06:14

I’m all for helping family out when needed, but this is just taking the piss. If the in-laws were expecting you to babysit, they should’ve checked you were available before giving this gift.

It was so rude of them to basically offer on your behalf and just assume you were available and willing.

Don’t feel guilty for taking your much-needed break; this is not your problem to solve.

ChateauProvence · 15/07/2026 06:09

Surely this is just one of this things as a newlywed you have to suck up if you get married after your children if you don’t have childcare then to take them with you on honeymoon. 2 weeks is a long time for the child and for any adults babysitting them tbh.

It's MN so the majority will say you're not being unreasonable because on MN everyone is ridiculously selfish and only ever wants to spend time with their DH and kids. But in real life it's unkind and a bit odd that you don't want to have your niece for a week if you're close to either your sister or your niece (or want to be).

Don't be so ridiculous. OP has said:

'before my niece started school, I looked after her once a week to save them nursery fees. We also regularly babysit. My kids babysit too.'

This has been sprung on her by her sister's in-laws with two weeks' notice. Her PILs should have organised childcare before booking the holiday. They should look after their grandchild for the two weeks their son and DIL are on their honeymoonn as part of their 'gift'.

And why didn't the sister check with everyone before booking the honeymoon?

Because the sister didn’t book it, it was a surprise.

RigsbysCat · 15/07/2026 05:57

Imo if you get married AFTER having kids, then you forfeit your right to a child free honeymoon. They can have a family holiday instead. Your poor little neice being expected to be passed around for 2 weeks among reluctant relatives.

Your sister and her in laws are being totally unreasonable here. As others have said if the in laws think a child free honeymoon is deserved, then they can provide the child care .

LokiDoki75 · 15/07/2026 05:57

“My sisters in laws have contacted me to say that we can sort this between us and let my sister and new husband have a lovely honeymoon.”

This is the bit that jumped out at me! Tell sis and her in-laws there’s nothing to sort out between you, you can’t do it. If the in-laws can’t do it either, Sis will have to either accept that they’re taking their daughter with them, which is what BIL thought they were going to do anyway, or not go for so long.

Out of curiosity, do the in-laws babysit their granddaughter very often?

Jane143 · 15/07/2026 02:40

I think you’re being selfish. You could share the child care between you. And why is GCSE prep so stressful for you? Surely it’s your child that took the exams? You all seem rather pressured when actually it’s the 8 year old that suffers the most being unwanted by all the family. I’d contact your sister and say you’ll help share the child care between you all and she can have a nice honeymoon. You could have some lovely beach days which are cheap and fun and help bonding with your neice. Your husband would probably enjoy it too, the weather is currently very nice so you could do picnics, beach etc, much more exciting than just hanging around for two weeks with your husband alone. Your children my enjoy it too and maybe help entertain their cousin?

And why didn't the sister check with everyone before booking the honeymoon?

Supersleepysheepy · 15/07/2026 05:39

I think leaving an 8 year old for two weeks is too long, they should go for a week and then it's a few days with you and a few days with other family. It's nice of her in laws to allow them use of their holiday home, but it isn't exactly a gift really, they've just decided not to go for a couple of weeks. Kind but not a huge gesture, not as big a deal as two weeks of full time childcare would be.

Take a week’s annual leave to look after their child?

No way.

Your BIL and his parents made massive assumptions.

I would just say yours and your DH’s AL is very precious and you have plans and won’t be taking time off work to childmind.

You have done a LOT of childcare for your DSis and BIL in the past and they are taking you for granted.

Did the BIL do this?

The BIL did not, he was expecting to take his DD. It’s DSis who wants to leave her at home.

permanently · 15/07/2026 05:21

In-laws need to supplement gift with a nanny to go with your niece! Two weeks is too long and completely unrealistic. Hurtful even. Your time off is well deserved and precious.

Do you not think it’s OP’s sister who is being selfish asking her to give up her annual leave when she’s already being doing plenty of childcare during wedding planning?

There is no reason her sister can’t take her child on the holiday and take her to the beach and on picnics rather then just hanging around with her husband who was expecting his daughter to be joining them anyway.

I very much doubt two teenagers who have been focusing on exams and are probably looking forward to some down time, want to entertain a much younger child and I don’t think it’s fair to expect them to be put in the awkward position to have to do it if she wants their attention.

I looked after my niece and nephew a few times when my sister went away and they missed their parents and were bored without their home comforts and wanted constant attention and entertaining and didn’t sleep well at night.
I was exhausted after two days and refused to look after them longer when she asked. I love them to bits but didn’t enjoy it and neither did they.

OP and her husband have made plans to spend quality time together so I doubt he’d be keen on giving that up to look after his SIL’s child instead.
It would probably be stressful for the whole household and it’s not an emergency situation when the obvious solution is for the child to go away with her parents.

I don’t know if you just have an idealistic view and have never been in that situation or if you just struggle to set boundaries yourself?
it’s usually people who try to always “be kind” that get taken advantage of and then try to pressure others to be the same out of resentment or by thinking they are a better kinder person sacrificing their own time and resources for others.

I used to bend over backwards for people thinking that it made me a good person to always put others first then realised I was always the one giving.
It was so deeply ingrained I’ve had to have therapy to learn how to set boundaries.

I’ve realised it’s not selfish to put myself first when I want or need to and the majority of people will also usually put themselves first.
On most threads like this it’s inevitable the “be kind” people will comment and often they are the ones making unkind comments calling the OP selfish for not being a martyr.

I’ve noticed most of the expectations are on women as well and men don’t think twice to saying no and aren’t criticised for doing so.
It gave me something to think about the next time I was volunteered for something that wouldn’t be expected of by a man.

SheilaFentiman · 15/07/2026 04:41

And why is GCSE prep so stressful for you? Surely it’s your child that took the exams?

@Jane143
It’s a concentrated period of providing emotional and practical support. It’s draining. Lucky you if you didn’t find it so - or perhaps you haven’t been through it yet?

Waitingforthesunshine24 · 15/07/2026 04:03

Hey OP!
I am dumfounded some people feel it’s ok for you to give up your time off or as if anyone has the right to question what you want to do with YOUR two weeks off! You are not obligated to do anything for anyone with your two weeks of time. I say this as someone who has been in this position many times and finally learned my lesson. Piss taking at its finest sister or not.
I echo what other posters have said, you have children and become a parent that comes first, tough titty for a long arsed honeymoon. Suck it up buttercup. A weekend at most and she is lucky to get that!
My son was 18 months when I got married, we didn’t expect anyone to do anything. We had some help in the evening from grandparents but we all went back to our home and are yet to have a “honeymoon” 5 years later because we had a small child and I’m completely happy with that, wouldn’t expect any less. Any time away we go
together.

Your sister sounds like a little princess.

Enjoy you’re two weeks off :)

Hotandpointy · 14/07/2026 21:46

This is why getting married before you have kids is a good plan!

Definitely wait 8 years to get married with a 8 year old then need a proper honeymoon. That ship has sailed.

user1492757084 · 15/07/2026 03:39

Two weeks to too long.

Given that your DH is not on board, I would look after my niece for two nights straight after the wedding then hope that her grandparents could look after her for the remainder of the time. At eight, she would be old enough to accompany GP to shops, appointments etc.

Are there other Aunts who could share as well?
It is lovely that the two are having a honeymoon. If I were on my own, I'd be happy to look after her for longer.

Mumtobabyhavoc · 15/07/2026 02:52

The in-laws gifted the holiday knowing the child either went along or needed looking after. They should be on the hook for the chikd care, I think. I would simply say, After everything I've done to help out I need a break. I have my own family to attend to.
The sister should absolutely understand and there should be any expectations, guilt or hard feelings.

You dont sound close to your sister. The wedding stressed you, and her "child" is actually your niece or nephew. Words matter. You sound like they're the neighbours kids. So you arent close to him or her either. Tbh you dont sound like a close family at all from how you describe it 😂
maybe there are some unresolved issues? Assuming no health issues etc with the niece or nephew or yourselves, typically that'd be a great gift to your sister.
I absolutely love mine and my sister so it wouldn't even be a question for me to look after them, that'd be a gift to me! If they're such a nuisance to you then don't do it of course but I guess also accept this isn't typically what a close knit family would do...

There’s nothing typical there at all. All people and families are different

reprohensiletail · 15/07/2026 02:31

Nah, they should have planned better. (What was the point of keeping it a secret at all, if they were telling her before the wedding, anyway?) Having your niece for 2 or 3 days would be enough. They'll have to find someone else in the family or among their friends who can cover the rest—or just take her with them.

bridgetreilly · 15/07/2026 02:02

Two weeks is a long time to have someone else’s child, even when you aren’t exhausted. No.

NoLifeguardOnDuty · 15/07/2026 01:53

Lemonymint · 15/07/2026 01:26

My own personal view is that ideally you have children after marriage. The least I'd have expected is a man to put a ring on my finger before I'd be risking stetchmarks and droopy boobs. Why have children with somebody who hasn't made a legal commitment? And yes, I did have a childfree honeymoon. No, I'm not Catholic or particularly religious

I have kids and I'm not married, I've been with my partner for 20 years though. All three kids are jointly ours. I'm not planning on ever getting married. I could but it would literally only change my surname.

We're obviously coming from complete opposite views on this. I doing think either is right or wrong by the way.

Can I ask why you wouldn't have a child unless he'd put a ring on your finger? If you loved each other and had been together a few years? What does that mean or what things would it really change? If you're happy and committed to each other anyway what does a wedding change?

NotHappyFamilies · 14/07/2026 22:20

My sisters partner was fully expecting that their child went with them. It’s my sister that wants to go without her.

That’s nice of her! Your sister isn’t big into considering other people - is she? Poor kid if she gets wind of this. I would consider a week long a very reasonable time for a child free honeymoon when you have a child. I’d stick to your guns and offer a weekend. You and your family are just as important too. The work and school year is long and summer annual leave is precious. As someone who is also help care for a sick in law atm I also understand the demands of this too xx
