Sisters children and step child and our holiday

My parents moved back to my dad’s home country in March. We plan to visit them in October in the school holidays.

My sister has asked us if we will take her children and step child with us so that they get to see our parents but mainly to help with childcare as she and her partner have to work. Her partner is away with work that week and the week after.

My parents are ok with us bringing them all but I know it would end up with us looking after the youngest. Our children are 16 and 14 so we are at the stage where we can relax on holidays. My sisters kids are 15 and 13, step child is 7 so she still need looking after and more supervising.

Are we unreasonable not to take them with us or only take the older 2? We haven’t had a summer holiday this year so we were looking forward to relaxing holiday. We suggested just taking our nieces but got the usual stuff about treating them all the same. She’s not the same because she is 7 and needs looking after, and yes, also, she isn’t our niece so it is different.

DS can’t take the week off as she is too busy at work with a project at that time apparently. My husband says we may as well stay home if we aren’t going to be able to relax properly and it’s gone from something we were all looking forward to, to something that we don’t want to do. We are all reasonable happy to take our nieces as they don’t need looking after as such and they won’t change the vibe of the holiday.

My sister insists step child is ‘easy’ so we will be able to relax. That won’t be the case as I will feel very responsible for her and obviously she may miss her dad, my sister and her mum. She lives 50/50 between her mum and dad. Her mum is on holiday and this is her dad’s time. He’s away with work which annoys me more. I also find it strange that the little girls mum is fine with her coming away with us when we have only met her mum twice. I feel sorry for the little girl quite honestly, but we really want a break.

Sorry if it’s all a bit jumbled but hope I’ve explained it all. What do you think?

YADNBU,

Your BIL has dropped your sister in it and she is trying to pass the buck.

There is no way I’d take responsibility for an unrelated child I don’t know well on a foreign trip for two weeks when it’s not even clear if one or both biological parents have given consent. Anything could happen. And that’s before you consider the extra work involved. There will presumably be extra cost?

Lots of children are not keen on holiday clubs but as most parents don’t have bottomless annual leave, they are a fact of life.

mindutopia · 23/08/2026 19:35

It sounds like she needs to organise some annual leave for another time and actually visit her family. You aren’t the nanny. It’s perfectly fine to not want to take other people’s children on holiday with you.

Also like hell would I allow my 7 year old to be hauled off to another country with my ex’s new girlfriend’s sister, some random adults she’s never met and a bunch of teens.

JaninefromEastenders · 23/08/2026 19:34

This isn't your problem OP, it's your sister's problem. She wants the children in her fairly new blended family to be treated in exactly the same way, but her relatives are not yet ready to do this because they don't know the little girl very well, and it doesn't help that she's much younger than the other children and needs different things. You need to tell your sister that, and repeat that the older children can come with you but not the younger one.

"Most 7 year olds are easy to look after."

Sorry, but they're really not. They can be lovely kids and interesting, but they want to do small child things which OP, her husband and the teenagers won't want to do. They'll whinge and cry when you have to leave an activity, you'll have to cajole them into coming with you and leaving the playground etc. and if they're at all spoilt by their parents they'll be demanding toys, fairground rides, etc. all the time.

I don’t think I’ve ever met a 7yo that winged and cried or had to be cajoled into doing things.
I don’t think most 7yos are difficult in that way.

But it’s the having to look after them that’s the issue.

The older ones can be left to their own devices all day and night without much worry but the 7yo needs actively looking after.

On top of that, a child that is not related needs extra looking after too.

BudgetBuster · 23/08/2026 19:34

Haven't read the full thread but if you weren't going on this holiday... what would they be doing for childcare? The 7 year old has a mother, a father, at least one step-parent... and none of them are willing to take a few days off to look after her?

GreenCaterpillarOnALeaf · 23/08/2026 19:33

I would say yes but in our family we have a time honoured tradition of paying the older ones to babysit on holiday. My mum babysat her younger siblings, my siblings babysat me, I babysat my brother’s first child and now she babysits my kids. Obviously depends on the maturity of the older kids, and no you can’t have them do it the whole holiday - but it works great for us. Also as a teenager I really actually enjoyed it. Once you’re older you can’t really play without being seen as weird, but if you’ve got a little kid with you then suddenly you’re a saint for looking after them.

Obviously speak to your kids about it and do what fits your family, but in my experience it’s always been great. I really think it’s part of the reason we are a close family. I also think it kind of helped me decided I definitely wanted children. I mean nothing prepares you for the reality of being a parent but having some experience with little kids and tantrums ect did help me.

Another vote for no. With bells on.

JLou08 · 23/08/2026 19:27

I've never met a 7 year old that behaves that way. I suppose it's dependent on the family/group and the dynamics. I've done big holidays with extended family and the teens and primary school kids all hang out together, sometimes with the adults, sometimes without. It's only been babies and toddlers who have needed things to be adapted or thrown any tantrums.

Clue there might be primary school kids plural. The 7 year olds have age mates. That won't be the case here. She'll have nobody of similar age to play with.

Maybeitllneverhappen · 23/08/2026 19:32

Also (!) which country are you going to? Some places it is very difficult to take a child that isn't yours and you need all sorts of paperwork or even authenticated documents which are checked on entry. Teenage nieces are related and can speak for themselves; an unrelated 7 year old is completely different

Her mums side of the family won’t help out when it’s on her dad’s time. Her dad’s sister helps with childcare odd days but will be at work. She doesn’t have children so keeps her annual leave for non school holidays. Sensible woman. 😂 My sister and partner usually sort the holidays between them but he’s away for 2 weeks and she has a big project ending in October so it’s not good timing.

Then stepniece will have to go into holiday club even if she hates it and wants to spend time with her stepsiblings.
Id also point out to your sister that she is going to destroy her relationship with her own children if she refuses to let them go and then expect them to babysit the 7 year old during the holidays especially when the could and should be spending time with their extended family. Your sister needs a reality check asap.

TBF nothing OP has said suggests she'd be willing to take a 7 year old niece to whom she was biologically related either. She has clear objections to providing the care a child of that age would inevitably need.

I don’t think I’d want to take a niece who was 7. It would be easier though. When my nieces were little and would have a tantrum or be whinging, I would feel ok to be a bit stern with them or ignore them, like I would do with my own children because ‘biology’ I suppose. They know they’re loved, it’s soon forgotten because you have that history and bond with them. With someone else’s child, I wouldn’t feel I could do that. It would be like having a guest constantly where you all make an extra effort and don’t quite be yourself.

I know I would spend the holiday making sure the 7 year old was ok, eating enough, drinking enough, watching her more than I’d have watched my own, worrying more if she fell over etc. I would be very aware that she could feel uncomfortable or sad so I would be constantly compensating for that and not relaxing. If it was my actual niece, I wouldn’t feel that way. If my niece had an accident in my care, my sister would know it wasn’t anything suspicious, but another person wouldn’t know that. It’s just not the same.

Would you even be allowed to do this? I have to travel with a letter as does my ex husband with permission from each other to take OUR kids abroad. We've never been challenged but surely this could potentially be flagged at customs.

I personally would never let my kids abroad with my ex husbands partners siblings that they'd only met a couple of times.

Anyway though I'm calling out the dad as being a childcare dodger here.

ThatBreezyScroller · 23/08/2026 19:31

Purely from the step child’s point of view - you should definitely not take her.

How awkward for her to be in a home with people she doesn’t know and around only older teens or adults.

I would say take the older girls but then you say they want to spend the week seeing friends and going hobbies etc - something they won’t be able to do if they come with you.

I would say to your sister that you will not be taking the 7yo but that you’re happy to take the older ones if she wants.
If she says no, she says no.

I was with a 7 year old today and a different 7 year old a couple of weeks ago. I don't have kids of my own, but I can see what 7 year olds are like. I love both these kids very much, but they are hard work. Perhaps you've forgotten what it's like?

outerspacepotato · 23/08/2026 19:30

Taking a 7 year old that you have no legal relationship to out of the country is extremely problematic.

Has the girl even met your parents?

This is batshit and I wouldn't do it. What if she becomes ill?

TeaCupTinsel · 23/08/2026 19:29

I'd refuse to take any of them. Explain that you just want to enjoy a family holiday and you don't want the responsibility of any other children. They'll most likely see it as unfair if you agree to your nieces going and not your step-niece.

OlderGlaswegianLivingInDevon · 23/08/2026 19:27

Wow another father who isn't actually doing his 50/50 and is happy for extended family to take his child out of the country.

has your sister's partner even met your parents ?

If I were the little girl's mother and knew about this in advance it would be a firm no.

Poor little girl, father can't be bothered. He needs to sort his week out.

MissRaspberryRipples · 23/08/2026 19:26

You're not unreasonable. Your sisters partner and his ex are the most unreasonable. He should have informed work that he couldn't work away that week due to it being his time with his child. Her mum is ridiculously unreasonable and downright stupid for thinking it would be ok for a couple of virtual strangers to take her child out of the country. As much as you'd look after her she doesn't know you. I would say she either accepts that you can take her teens but not the 7year old or you don't take any of them at all. Seems your sisters partner can't plan his time properly if he wants childcare he will have to sort it out himself rather than find it ok to leave your sister to figure it out for him

Mumtobabyhavoc · 23/08/2026 19:26

"and yes, also, she isn’t our niece so it is different."

This says it all. 🙄

Wowzel · 23/08/2026 19:23

Surely your sister and her DH just need to book a weeks holiday club for the 7 year old?

Maybeitllneverhappen · 23/08/2026 19:22

What did your sister do with the 2 older ones when they were little?

Loulou4022 · 23/08/2026 19:21

Why on earth has your sister’s husband booked to be away with work when he should know that his daughter is on half term holidays and with him! Actually that would have been an ideal time to have some one on one time with her if the older 2 were away with you and the grandparents. Does the DSD mum even know about this suggested plan would she be happy with it!
TBH regardless of any of that her Dads lack of planning does not constitute a problem
for you!

However lovely the child and regardless of the relationship to you, it would completely change your trip. None of the teenagers are going to want to hang out with her much and you are going to be less relaxed with a child (who is not your own) and so much younger. Repeat your offer to take the older girls, it's up to your sister and her DH to sort childcare. Are there no family of the mum's or dad's who can help?

Her mums side of the family won’t help out when it’s on her dad’s time. Her dad’s sister helps with childcare odd days but will be at work. She doesn’t have children so keeps her annual leave for non school holidays. Sensible woman. 😂 My sister and partner usually sort the holidays between them but he’s away for 2 weeks and she has a big project ending in October so it’s not good timing.

We feel like we should be able to just take the older two without it being a huge issue. My nieces are aware that my sister is trying to make us take all of them and have said it’s unfair that they might not be able to go just because we won’t take the younger one. I sympathise with them. They should be able to do things without their step sister.

If it has to be then we will take none of them but it doesn’t feel right to me to make them miss out. It doesn’t help anyone really for the older two to miss out.

I’d offer to take your nieces, and if she refuses unless you take all three I’d say no and not take any. I’d also find a way to ensure your nieces know that they are invited. She’s yet another person that has fallen into the myth of the “blended family” that just never exists.
