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?

I agree with the poster who said the groom’s family are cheeky for volunteering your annual leave. The SIL needs to butt out, too.

Your sister is odd for not only expecting two weeks of childcare but wanting to be away from her 8yo DD for that amount of time, especially after such a huge event in a very young child’s life.

Well done to your new BIL for expecting his (step?) DD to go with them.

You are DNBU to say no.

I’m reading a few posts whilst watching the football.

When I said my sisters in laws, I meant her parents in law. Sorry for confusion.

I text them back today to say we can do a couple of days but no more and I haven’t heard anything back from them.

Also, the man my sister is marrying is my nieces biological father not her step father.

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?

Oh stop being bloody silly. You’re the sister, aren’t you.

The trouble with offering to do a couple of days is that you are reliant on whoever is next taking your niece. If they say no, don’t answer the phone or similar then what are you going to do? Unless it is the final few days and you can take her back to her mum on the last day.

Why did the in laws keep it a secret? And how does your sister going to say ‘hey kid, me and your dad are going on a really nice holiday for two weeks but you’re not. Sorry’. If they had told her ages ago all this could have been thrashed out.

We took our 6 month old baby with us on honeymoon. 2 weeks is a lot to ask of you I think, maybe do a long weekend?

I am once again begging people to read the OP's posts.

The groom was expecting to bring their DD with them. He is not an idiot man (though I don't deny those exist!)

Hello, I read the thread a bit more and actually edited my comment, realised it wasn’t the man’s fault (makes a nice change!), so your reply doesn’t make sense anymore but I just wanted to say that’s why.

Honestly OP stick to your guns- you are allowed to need a break!

I'm currently exhausted from work and my own family. If I was also dealing with helping my sibling organise their wedding it would be too much- I am literally counting down the days to my holiday now.

If it was sudden to dumped on me that I was now going to be responsible for my nephew then I'd be gutted.

Unfortunately this is what happens when you have kids, you can't just assume you can disappear for 2 weeks of uninterrupted adult time!

SheilaFentiman · Yesterday 22:31

YY @44PumpLane - when you are gritting your teeth to hang on through a stressful time, because you know you have a holiday/night out/spa day or whatever coming up, it hits so much harder if it looks like you might lose that break!

I think it’s a mistake offering a couple of days and I would withdraw that offer. It will be disruptive for the little girl anyway being shunted around. They need to have a proper plan for her care for the whole two weeks.

winter8090 · Yesterday 22:45

i think it’s best you decline if you don’t want to do it. I feel two weeks is too long to be away when you have children especially to rely on others but I also feel it’s a bit mean spirited not to offer for a few days.

Ah, in that case, I take it back about the in laws. Their offer of a holiday, shouldn’t involve you providing any sort of childcare (let alone the bulk of it!). Good for you for being clear.

Have you heard anything from your sister?

Just reiterate NO.
2 weeks is a long time to leave a child. They should take dd.

BruFord · Yesterday 23:08

@Jane143 Personally, what I find most surprising is that the Mum wants to leave her DD for two weeks and expects other people to organize the childcare. The Dad wasn't planning to leave their DD behind.

It doesn't sound as if many posters, myself included, know parents who'd do this to their eight-year-old and the fact that they're getting married doesn't make any difference. A few days away is the max - when she's older, they'll have decades to take long holidays by themselves.

Sorry, but when you have a child, you don’t get a ‘proper’ honeymoon! Not unless it comes with robust childcare that is arranged well in advanced by people who have actually offered.

Being guilt-tripped into being any part of it, is just going to lead to bad feeling.

Poor 8 year old not being with her mum/parents for two weeks at the last minute, just after they get married as well-if I was the parents, I’d be making sure she felt 100% included in family life, not shunted onto exhausted family members at the nth hour before their much-needed summer break.

No, no, no.

Agree with this 100%. You’re absolutely in the right OP. Don’t get pressured into anything. Maybe the PILs can look after the child for night or two but can’t believe the couple expect or even want much more time away from their poor kid.

Been married 18 years. Nobody has ever looked after my children for even a night away, and I certainly don’t expect them to. YANBU
