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?

Can I ask, how much help did she give you with your kids .

Asked and answered by earlier posts - DSis lived abroad when OP's kids were small and only came back when pregnant, so not much, by circumstance.

And the Op looked after her niece one day a week to help her sister save on nursery fees. As well as babysitting when asked.

She's a great sister and aunt.

Just because you're not going away long it's your holiday for the two weeks. Tell them no and refuse to keep discussing it. Don't get into details of being tired because of the wedding or whatever, they'll only keep argue it. Just repeat, no, it's our precious holiday time together and when they bring it up again, smile and say we already discussed this and change the subject.

I don't how much time off you get, but I can only get one chance at two weeks off a year. Would not entertain childcare in this situation.

You already sound like a wonderful sister for all the help you’ve given so far . You deserve a break , your sister also sounds really fortunate with her in-laws and support. Can I ask, how much help did she give you with your kids . Always amused by people who never helped but then expect it themselves when they have kids .. I’ve had this a bit , it was assumed recently that l’d mind a sibling dc as I wasn’t partaking in a particular family activity and as I was at home (my kids are also older ) they could just drop them off but I simply said , sorry I had plans and was chilling out that day. Unfortunately it’s all a bit vicious cycle , no support breeds no support… And I’m not bitter , I had a fab day !

SheilaFentiman · 15/07/2026 10:20

@mmmarmalade the key issue with changing the date to a different fortnight is that both the ILs and OP are working. I would guess that ILs or other family (or Airbnb!) are in the holiday house on other dates.

If DSis had had a conversation with OP saying 'we want to do a long weekend at a posh hotel as a mini-honeymoon, can you have Suzy Saturday night if ILs have her Friday? are there any weekends that would be good/bad for you over the summer?" then OP might well have been OK with that. Not this, though.

BeGreySnail · 15/07/2026 10:19

Tell them you've rearranged your two weeks off for after the honeymoon. Or stick to your guns, you deserve the break!

It’s fine to ask your sister to give up her annual leave to babysit your child; it is not fine not to accept the no.

To be fair, OP hasn’t said what her sister said when she said no.
all she’s said is that her in laws have been in touch to suggest they sort it out between them. They may well have taken it upon themselves to try and make it doable.

Vartden · 15/07/2026 10:16

Im very close to my sisters but would definitely say no to this. But ,they would never have asked me because they would know its a completely unreasonable request!!

U53rName · 15/07/2026 10:15

bitmiffed26 · 15/07/2026 10:14

of course she does. I haven’t said anything debating that.

still no need for people to start slagging off a mum for being comfortable for leaving their child for fortnight.

which was the point i was making that you originally responded to.

OP doesn’t want to give up the only annual leave she has had since Christmas. She has the right to have her annual leave.

Which is fine. But your response was along the lines of ‘usually those shouting about a village are those that benefit the most’ or something along those lines. I was saying that is not the case with me.

also, ‘villages’ don’t begin and end with children. Let’s say 30 years from now the OP makes a post about how she now lives alone, children have moved away, she’s had an op and needs some assistance. Only person who can do it is her sister, but she won’t because she didn’t look after her kid for a week years ago. That would be pathetic. So saying OP didn’t receive help with childcare from her sister so why should she give her more help than she already does is such a silly argument.

SheilaFentiman · 15/07/2026 10:11

@WannaSweetie OP can absolutely say no to this because there is the option of DNiece going with them, as was the original plan

MyDeftDuck · 15/07/2026 10:10

It would be a very firm NO from me! Their child, their responsibility. Do not enter into any negotiations with her in laws and actually, I’d book random short breaks for the week in question to make really uncontactable and unavailable! CF!

Avie29 · 15/07/2026 10:08

Nope i wouldn’t do it, my sister recently asked me to look after her 6yo and 1yo for 9 hours and i refused let alone 2 weeks! Its all well and good people saying oh well can’t you just do it to do a nice thing for your sister but its not a small thing she is asking especially with your own children and busy lives.

Iris2020 · 15/07/2026 10:08

It's incredibly presumptuous of your Sister to expect childcare like that if it was her big wish to have a honeymoon, she should havr asked you ages ago and not expected any other help for the wedding.

mmmarmalade · 15/07/2026 10:07

Would it make any difference if they had arranged a date for their honeymoon around when you would be available, willing and less washed out? I'd think long terms - it's your sister, a one off, etc - (depends on how you feel about your on going relationship with your sister, her husband and in laws) - yes - they have handled it very badly but clearly she/they had a lot on her/their minds and were feeling overloaded anyway (hence your invaluable help). Let's say they could put the honeymoon off for a month or two (or longer) and then properly explore child care arrangements between you and the in laws - that's what should have happened - I assume the in laws can be flexible about when they gift them time at their holiday home.

The topic of this thread is OP’s experience; not yours. OP has provided plenty of free childcare to her sister. Her sister has never provided OP with free childcare. OP’s sister now wants a claim on OP’s annual leave.

It’s great that your sister reciprocates—OP’s sister doesn’t. So we are advising her accordingly.

WannaSweetie · 15/07/2026 10:05

I’ve been in this situation with my DGC it was a case of well we’re having a 10 day child free honeymoon, it’s booked, & you’ll all need to arrange how child care is going to work (cheers!)
I think you’re going to have to factor in that you’ll end up having to look after your neice, so be firm on negotiating how long & when - couple of nights/weekend, when it suits you, & keep repeating no a full week is not possible as we have plans/booked events etc. The PIL have gifted the 2 week break, it’s up to them to organise, not dictate

Delatron · 15/07/2026 10:03

The OP hasn’t had any time off since Christmas - she doesn’t really need to justify why she wants two weeks annual leave.

bitmiffed26 · 15/07/2026 09:54

Well, I’m glad I don’t run in the same circles as you if that’s your experience.

My sister and I are each others village, and we are very much on a level playing field with regards to effort put in.

i appreciate that isn’t the dynamic of all families, but that’s mine.

The Op IS providing childcare. She's provided plenty in the past and is providing it in the run up to the wedding. That shouldn't mean she cant take time off with her husband and kids!

i’ve said several times that it’s fine if she has said no and doesn’t want to.

I have three siblings, we're all married. My sister is closest in age to me, lives very nearby and I was her maid of honour so was most involved in her wedding run up compared to the others.

I didn't even take two weeks off to recover from the stress and overwhelm of my own wedding so I'm baffled as to how you've expended so much energy on your sister's.

If my sister had her children at the time of her wedding yes, I'd absolutely have said I'd have them for a week and my parents would have them for the other. I'd have a fabulous time doing all the local things that 8 year old love doing but 18 year olds have grown out of. Then I'd use the other week for a holiday with my husband and our older teenage children.

As someone else has picked up on, it doesn't sound like you're particularly close to your sister or your niece/nephew, especially when you refer to them as "her child". I like my nephews!

Also, how often does someone get married? This isn't just some random holiday.

Yes, it does seem unfair that the goalposts have been moved this late in the day but I wouldn't be so butthurt about it.

All that said, I haven't ever been away from my kids for a whole fortnight. Maybe 8's old enough but when we got married our older two were about 4 and 2 years old so we just went away for a long weekend for our honeymoon and our parents were very happy to help out.

Honeymoons don't have to be a trip of a lifetime to be special, they don't have to be super long or expensive or far away.

It's lovely for people who can afford to do that but we only manage to make one week away in the UK work for our family most years so a 2 week honeymoon seems an incredible treat!

Not saying I'd jump at the chance to have my nephew in a holier-than-thou way. I'd genuinely just be happy to have them. I do think 2 weeks starts taking the piss though so I'd definitely pitch 1 week with you, 1 week with her in-laws. And let her have the honeymoon then let you have a special week the week after.

And would your DH be equally delighted to spend his week’s AL doing all the things 8 yos like and you did years ago? And having a precious week’s AL used up adhering to child-friendly hours etc?

I dunno. I love my DNS but don’t now see childcare for younger children as a holiday activity per se!

Selective reading, much? OP has clearly said that she hasn't taken leave since Xmas, she's been supporting her children through exams and her DH with a very sick mother, including doing some caring.

But even without any of that - OP has booked two weeks of leave in the summer, to spend with her kids and DH, which is a very normal thing to want to do whether you are knackered or not!
