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?

I would say no to all children. I wouldnt want to be responsible for a 13 yo either.

They can arrange their own holiday to see them when they can get time off work.

Arranging a family holiday and excluding a step child who has been part of your family
for years is a horrible thing to do. Declining to take a young step child on a holiday you didn’t invite them on but have been asked to take them on because their parents want you to resolve their parent’s childcare issues is very reasonable, even if you’re giving more serious consideration to taking your nieces. Looking after a 7 year old is absolutely worlds apart from caring for teenagers. It’s an unreasonable request to have made of you and an unreasonable expectation that a seven year old would be able to navigate a big trip like that without a parent.

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.

It's not you who's making them miss out though. It's their mother. Their grandparents want to see them, they want to go, you're happy to take them - it's your sister who would be the one saying they can't go because she doesn't want them to go without their stepsister. That's up to your sister, it's a parenting decision she's making for her own DC and nothing to do with you.

I wouldn't worry about excluding the stepchild. As nice as she may be, she's too young for this holiday, she barely knows you (has she ever even met your parents?!) and she's not your niece 🤷.

It's the two step parents who need to treat the DC in their blended family equally, nobody else. They're the ones who chose to blend their families. None of their extended relatives asked for that situation, weren't consulted about whether they accepted it and didn't agree in advance to treat all DC equally. So it's a bit much for the parents to have decided for you, without your knowledge or permission, that you're to treat all DC equally and as if they are all your blood relatives.

It's not for you all to have to treat the stepchild as if she was a blood relative if you don't want to and don't feel that way about her. It sucks for the child of course, but that's life. You can't be responsible for the emotions of random children just because their parent and your relative decided to remarry/cohabit. So I wouldn't feel guilty at all about inviting your nieces and saying you won't take the younger child.

It's not even a difficult situation regarding potentially making the stepchild feel like the odd one out for no reason. If she asks why the others are going on holiday and she isn't, she can be told they're going to visit their grandparents. Why would she want to go visit their grandparents?! It's weird. Do they go with her to visit her grandparents? I somehow doubt it. It's really neither here nor there that her step siblings grandparents just happen to live abroad. All things in life are not equal.

Dearg · 23/08/2026 18:05

YANBU.

From the standpoint of the 7 year old, she’d be going away with two adults whom she barely knows, because her own parents and stepmum are useless.

Not acceptable. Your sister needs to sort it out with her own husband.

@Dearg Exactly. It's totally unfair on the poor child. Visiting your parents is a red herring tbh, what it really boils down to is that her parents are unwilling to organize childcare for her so they're trying to guilt you into taking her.

Plus, you may even have trouble taking her to another country as you're unrelated, her parents will need to give permission for her to travel with you (No idea how that's done, an affidavit perhaps?)

CandidRobin · 23/08/2026 21:49

If OP treats all children the same as her sister demands and declines to take any of them with her, her sister is still left with her original problem and potentially additional resentment from her children. She cannot compel her children to babysit for her partner's child so they will need to use clubs even though the child doesn't like them as there's no other option. The teens will miss out on time with their grandparents and likely be bored. The sister will achieve nothing by preventing her children from going so should just do the right thing and let her children go.

WonderingAndOverthinking · 23/08/2026 21:49

Yeah, childcare is not your problem to solve. Hell, it’s not even your sister’s problem to solve!

Crazylittleworld · 23/08/2026 21:47

If they’ve been together nearly 6 years and little one is 7 then she’s been in your life a long time still. She would have been very young when she joined your family, she probably sees you as family more than you obviously see her.
I understand that it would mean you wouldn’t relax as much having a younger one, but don’t take any if that’s the case. Being so young when she came into the family she probably wants to see the grandparents as much as your biological nieces.

pinkyredrose · 23/08/2026 21:47

Unfortunately your sisters partner won't be able to go away for work as he has his child that wk. That's parenthood for you.

IJustMight · 23/08/2026 21:47

I would just say no, it's your only holiday this year and you're planning on enjoying it, not watching a 7 year old or requiring the young teens to look after a 7 year old.

You will take the cousins, but not the 7 year old if she wants you to. But if she insists they all be treated the same, they can all stay home with her. Be firm.

TheFlandersPigeon · 23/08/2026 21:46

TY78910 · 23/08/2026 21:35

Honestly, fair enough.

Would I still want the potential fall out with DSis? This has a lot of risk of becoming a family drama no matter how much OP explains its to do with age and levels of supervision.

It does, but there isn't a way around this that removes the possibility. If OP sucks it up and ends up not having the rest she wants because she's got lumbered with looking after a 7 year old she barely knows, she might not be able to contain her resentment. Since it's her sister, other family members present might resent OP for not having the spine to say no if entertaining a 7 year old has any kind of negative impact on the holiday. Or if (let's hope not) DSN has an accident, gets ill, ends up needing medical treatment, are Dsis and/or the parents going to have something to say then?

Dsis has introduced the potential for drama here, unfortunately, and there are now lots of ways it could ensue because of her unreasonable expectations.

What if the DCs see their step sister as a sister and equally wouldn’t want her to miss out? 6 years is a long time to form a relationship between kids.

@FallingDream has already said the stepsiblings dont want her to come and they want to go away with their cousins and aunt

How do your parents feel about seeing your step-niece, @FallingDream? They've known her for 6 years, since she was just 1, so they've seen her grow up and may want to see her too. Certainly, my grandparents felt this way about my step-cousin despite him joining our family when he was older than your niece. They were very hands-on types who loved being with kids though and I do appreciate not everyone shares this temperament; my in-laws can barely tolerate their blood relatives!

Obviously they mainly want to see us and their grandchildren but they don’t mind if she comes with us. They won’t be the ones looking after her though. That will fall mainly on us.

Shedsqueek · 23/08/2026 21:44

7 is too young and surely your sister shouldnt be arranging such things when the child has a mother who might have a say?

Hoardasurass · 23/08/2026 21:41

TY78910 · 23/08/2026 20:55

She’s not a random 7yo though. She’s the eldest sister… she is OPs step daughter, but her sibling’s sister.

She's not she a stepsister to both of the children. She has no blood relationship with any of the people going on holiday or to visit.
So yes she is a random 7 year old

TY78910 · 23/08/2026 21:35

TheFlandersPigeon · 23/08/2026 21:31

Yep. OP has said they don't want the youngest coming @TY78910. Dsis not only wants to add her to the trip against the two eldest's wishes but is also doing something that could lose them the holiday altogether. This is a lot of resentment to risk creating in the wider family because for whatever reason she can't just send the 7 year old to clubs whether she likes it or not and look after her solo in the evenings.

(I did suspect DBIL was being a deadbeat, but looking after each other's DC when the parent is working away seems a norm in their relationship so fair enough).

Honestly, fair enough.

Would I still want the potential fall out with DSis? This has a lot of risk of becoming a family drama no matter how much OP explains its to do with age and levels of supervision.

Well my brother was 6 years younger than me, and half the time I didn’t want him around, poor kid, when I was a teen, as I was a mardy so and so. Like a lot of teens, I should think. Luckily he’s forgiven me and and I grew out of my horrid stage.

Dependsoncontext · 23/08/2026 21:31

I would say no to all. I think your parents will much more easily be able to accommodate just your family. Your sister needs to organise her own visits to her parents with her children and step child.

Your sister can hate your decision but that is her discomfort to deal with.

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.

But they aren't her siblings and she only lives with them at most 50% of the time (assuming that they see their dad aswell its likely less). She is old enough to understand that her stepsiblings are going on holiday with their family as im sure she does when with her mum.
Also the older kids deserve time away with their extended family without having a much younger stepsister foysted on them, they didn't choose to have this child in there lives and shouldn't have their extended family time impacted by her father's inability to sort out suitable childcare on his time.

I missed the part where OPs sister’s kids had a father other than the DP, but regardless my opinion still stands -

I always find it rather strange that people in blended families on MN choose to see the blended more as layered - not quite a family. Blood isn’t always the be all and end all of someone’s relationship, family is what you make it. I would be absolutely devastated if I got in to a relationship with a man with a child and my family didn’t accept them as part of my children. It’s interesting OP mentioned somewhere upthread that DSis always insisted they should be treated equally - so there we have it really - if OP wants to say no, say no to all. Surely it’s a better holiday for her without any extra kids involved.

Because that is the reality of many blended families, if not the majority of them. In a blended family the children don’t have the same relatives in common, and it isn’t necessary to pretend that they do. The DSIS can choose how she considers her stepchild, but she cannot decide that for the rest of her family.

Perhaps the actual nieces are devastated that their mother married a man with a child, is now not only trying to insist that said child is something she’s not to them, but would allow them to miss out on their own family because of her.

TheFlandersPigeon · 23/08/2026 21:13

Yes, it's interesting that there's nothing about the feelings of the two elder DNs in the post you're replying to. I'd have thought Dsis would be more cognisant of the risk that her insistence creates resentment. Maybe she doesn't think OP would actually call her bluff and treat them all identically by not taking any of them.

UraniumFlowerpot · 23/08/2026 21:17

Even when everyone is exactly the same amount of blood related you don’t have to treat them all exactly equally in every single thing. It could be entirely reasonable to say we’re having a teen focused holiday this time, even if they’re all full siblings.

Add in that part of the point of the holiday is to visit relatives that are not actually relatives of the seven year old and it’s even more obvious that she would be a strange addition, the odd one out. 7yo must have holidays etc that she goes one with her mums family that her older step siblings don’t join in with? She must understand that the family is blended and there are different relationships to extended family?

TheFlandersPigeon · 23/08/2026 21:13

AnneLovesGilbert · 23/08/2026 21:09

You’re suggesting that OP’s sisters kids miss out on a holiday with their grandparents, aunt and cousins because their mum met someone who has a child with someone else. That’s what none of them going means. OP wants to take the older two, the older two want to go, OP’s kids want their cousins to go. The grandparents want all their grandkids to go.

All of these people will miss out on something lovely because the 7 year olds parents are away the same week and her step mum has to work and no one can be arsed to arrange suitable childcare.

Yes, it's interesting that there's nothing about the feelings of the two elder DNs in the post you're replying to.
