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?

Because a 7yo is more than capable of understanding the ‘my siblings are going on holiday but I’m not’ dynamic. It’s not fair on the kid. I have a 6YO DD who would be absolutely devastated. No matter what adult reasons there are for this split, there is a kid at the end of this. And I can imagine her parents thinking the exact same way if OP was to propose otherwise.

There are three kids. Two of whom want to spend time with their own family without an unrelated seven year old tagging along. They shouldn’t have to miss out on their own family because of a step sibling, and. nor should they be lumbered with providing childcare for her.

That isn’t going to promote cohesion, but will be instead almost certainly cement their view of her as a burden.

We are told that the youngest doesn’t like going to holiday clubs and wants to be with the older two. We have been told for years that we should treat them the same. I think it’s a shame that my nieces don’t get to see my parents because otherwise she will say we are favouring them but maybe it will cause less trouble to say no. It won’t solve her issue though.

Why can’t your sister take them to your parents another time?!

OneTipsyDreamer · 23/08/2026 20:26

Agree with others who have said the dad is a cheeky fucker. He only has her 50% of the time. How long has the step sibling been in the family? Does she even know your parents?
I don’t think anyone should be treating them all the same, they have different families, by that logic the 2 older ones should also go on holiday with their 7 year old step sister when she’s with her mum…. Which is ridiculous.

FallingDream · 23/08/2026 18:06

Part of it is that she isn’t our niece though. I would feel that I had to make more effort with her to make sure she’s comfortable.

Just don’t mention it. You’d have to make a lot of effort for a 7 year old regardless. Say you can’t take any extra kids. It’s ok to say I don’t want to be responsible for them.

TheFlandersPigeon · 23/08/2026 20:23

Mumtobabyhavoc · 23/08/2026 20:12

I don't agree.

Well, if you want to explain why a 4 year old helping with dressing and nappies is actually a relevant example despite all the obvious differences I'm ready to hear it.

canklesmctacotits · 23/08/2026 20:23

Your sister completely, totally understands what you’re saying and why you’re saying, and she can’t argue with the reasoning either. But she doesn’t like it. She’s got herself into a situation she can’t manage, and she guilt tripping you into not solving it for her at your own expense, rather than she sorting it out at her own expense.

It boils down to her work project versus your family holiday.

(Well actually it boils down to this poor child not having a mother or a father or a step-mother willing to out her first, and having to spend her school holiday with her step aunt visiting her step-siblings’ grandparents. It’s just awful).

Your sister and her husband need to sort this out between themselves. This isn’t your job. They blended their family, they didn’t blend yours and neither did you. I don’t know how they could keep a straight face saying that their jobs are more important than your annual summer holiday/visit to your parents. Outrageous. And why aren’t they thinking about this poor 7yo? With a shitty dad who puts his job first, a shitty mum who would rather go on holiday, and a shitty stepmom who tells her she’s the same as her own children but clearly doesn’t treat her that way?

ETA it’s actually really miserable, thinking about this little girl, spending her holidays with someone else’s grandparents rather than her own. Why can’t she go and stay with her maternal or paternal grandparents, her own family? Why should the poor thing have to spend it with people she doesn’t know, who aren’t related to her, who haven’t asked her to come stay with them? She’s just a childcare problem to all the parents and step-parents in her life. Heartbreaking.

samthepigeon · 23/08/2026 20:15

So what would happen to this little child if you don't take them with you? (I am not saying you should by any means, but I am wondering what the arrangements would be if he her dad is away and her step mum is working.)

They'd have to arrange childcare such as a daily holiday club at home or whatever

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.

This is exactly the reason that my parents won't have my step daughter overnight or really at all even though they will do that for my kids. It's not because they don't like her it's just that they feel as though they can't tell her off (like they would with mine) and would be too worried about something happening to her under their care.

I wouldn't take the 7 year old, absolutely not. It sounds as though you're quite happy to take the older two so I'd tell your sister that you won't take the 7 year old (due to her age) but will take the older two. If she refuses then her kids miss out I suppose.

TheFlandersPigeon · 23/08/2026 20:17

thepariscrimefiles · 23/08/2026 20:08

That's ridiculous. OP doesn't have to do anything of the sort.

It sounds as though this little girl's step-siblings don't want her to come in case they are expected to entertain her and look after her. They want a care-free holiday with their wider family, as does OP who was looking forward to this holiday.

I feel very sorry for this little girl but unless she is very self-sufficient and confident, I think she might be homesick without her mum, dad or step-mum and she won't be with anyone really close to her.

I think it's a bad idea and her father shouldn't have made plans to work away from home when he knew that it was his time with his daughter.

Agreed. And I wonder whether the 7 year old wouldn't prefer the holiday club anyway. OP barely knows her so can't be sure how she actually feels about them. In addition she appears to think she'd be getting time with her sisters, when actually it sounds like the teens want to spend time with each other not her. It's possible she'd actually prefer being in a familiar environment, and with agemates at holiday club.

Devonshiregal · 23/08/2026 20:14

wait so your sister's kids are not related to his daughter? (the 7 year old) how long has your sister been with this man?

and no it really isnt appropriate to take a 7 year old to another country. if anything happened it just isn't worth thinking about. Is the mum even that lax that she'd not put a stop to it?

on a random note, a 12/13 year old really does need supervising on a trip. I mean maybe not in terms of tripping over or being upset, but they're still kids in a foreign country.

eta why on earth would this kid want to go and see your parents in another country? so weird that your sister would even think this was a good idea.

SpottyPyjama · 23/08/2026 20:13

Your sister is a cheeky fucker and her husband is twice as bad. Imagine only having your child for 50% of their life and then trying to palm them off on your in laws who are going abroad? Awful human.

Apart from the obvious inconvenience you are being expected to to suffer, there is too much potential for things to go wrong. What if the child gets injured by accident and needs and emergency operation? What if the immigration authorities don’t accept that you have permission to be taking an unrelated child abroad with you? Fuck that.

Take your nieces on holiday and you will still be doing your sister and her husband a massive favour.

Mumtobabyhavoc · 23/08/2026 20:12

TheFlandersPigeon · 23/08/2026 20:08

It isn't.

The 4 year old presumably has met the baby more often than OP and her DC have seen the 7 year old. And nothing about what you've said explains how the very long hours of being responsible for a 7 year old OP and her family barely know would be covered.

It's correct that this situation is probably primarily about want, notwithstanding any potential issues travelling with an unrelated child. BIL doesn't want to take charge of his own child, Dsis doesn't want to take charge of her stepchild, OP and the teenage kids want to enjoy their free time. But your example clearly isn't of a situation where the 4 year old doesn't want to help, even aside from how totally different it is to taking responsibility for a 7 year old.

I don't agree.

Redburnett · 23/08/2026 20:10

I have no idea why anyone would expect you to take an unrelated 7 year old with you to another country. Would you even be allowed to, thinking about border controls and parental responsibility?

thepariscrimefiles · 23/08/2026 20:08

TY78910 · 23/08/2026 19:55

You either take them all or none at all.

Mumtobabyhavoc · 23/08/2026 20:02

Of course it is. Everyone in a family can help out according to age and ability.
This situation is simply about want and, I think, not considering the dss as family.

OP, does your sister, or more to the point, her husband, have a letter from the 7 year old’s mother explicitly saying it’s OK for you to take her out of the country ? I presume we’re talking about a trip involving Border Control and passports.

To be honest I wouldn't take responsibility for the child, step or not.

This is really important.

Sounds like a shit holiday, and completely different to what was planned.

They don’t want to be responsible for any 7 year old, let alone an unrelated one.

Deckchairsatdawn · 23/08/2026 20:07

This is madness.
What about the little girl's own grandparents? Surely that would be better all round?

Noadded · 23/08/2026 20:03

I wouldn’t take my 8-year old niece on holiday, never mind a child I’m not connected to.

If you’re in the teens already, holidays are easy! Add a 7-year old and you’re back into policing the pool, making sure they eat/drink/sleep enough, then there’s applying sun cream all the time.

Definitely not unreasonable to say no to the 7-year old.

GreenCaterpillarOnALeaf · 23/08/2026 20:03

FallingDream · 23/08/2026 20:00

My kids are mature but they don’t want to be arsed with looking after a 7 year old. I’m mature and don’t want to. 😂 I don’t think it’s mature to want to look after a child as a teen.

My kids and nieces aren’t thinking about whether they want kids or not. They are teenagers. They don’t need to be prepared for the realities of being a parent. My children are close to their cousins as they spend a lot of time together. I think they’ve got sense to not want to be around younger kids and their tantrums.

Edited

I mean we got paid… as a teen I saw it as “fuck yes I’m getting money” and then it helped form my opinion of having kids. I wasn’t a teenager thinking I wanted kids, but it’s something I looked back on. That’s fine if they don’t want to do it, but it’s an idea.

OnlyUsername · 23/08/2026 20:03

FallingDream · 23/08/2026 20:02

We have met the 7 year old more than twice. It’s her mum that has only met us twice.

Edited

Ahh I see! That makes a bit more sense.

MCF86 · 23/08/2026 20:03

The older two would just hang out with your own teens and be no extra work, your sister must know that even if she refuses to admit it!
I'm a step child and usually very much "treat them all the same!", which is what I was lucky enough to experience. But you cannot treat a 7 year old like a teenager!

Also, how would it be a fun half term for her anyway, stuck with a bunch of adults and teenagers.

grumpygrape · 23/08/2026 20:03

FallingDream · 23/08/2026 19:36

I meant in previous holidays when my sister has tried to tell my oldest niece to babysit, she hasn’t wanted to because she wants to see friends etc. Both nieces are happy to come away with us. They just don’t want to spend their school holidays babysitting and I don’t blame them.

OP, does your sister, or more to the point, her husband, have a letter from the 7 year old’s mother explicitly saying it’s OK for you to take her out of the country ? I presume we’re talking about a trip involving Border Control and passports.
