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?

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!

Maybe he hasn't "booked to be away with work", because he does one of those jobs where there isn't much option about when you have to be away from home.

My question would be whether a 7 year old wants to go on holiday with a family she has met twice. My DS is 8, has been away with his grandparents this summer and got homesick after a few days.

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

I'd frame it as unfair that your family holiday has turned into something else.
Go back to just going by yourselves and telling her to bring the kids herself when her husband is available.

This. Nice and simple.

this is your family holiday. Your children are old enough not to need you frequently and you can relax. Taking another set of children means you don’t have your much needed family holiday.

surely they can visit your parents as a unit another time. Convenience for them would mean you sacrifice your holiday.

also I’m freaked out by the potential complexities of taking the little 7 year old to another country.

In any case, nappies and help with getting dressed are unlikely to be applicable to a 7 year old and would usually only take a few minutes a day anyway. A 7 year old is going to need looking after well beyond that. It's not a relevant example.

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.

Mumtotornadoes · 23/08/2026 20:01

No I wouldn't take someone else's 3 kids on holiday. Even to visit family. That's you in charge of 5 kids, that's alot of kids. Most of them not being yours.

As a mother I also wouldn't agree to my exes, girlfriends sister taking my DS out of the country either.

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.

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.

Looking after 5 children is a big difference to looking after 2. I think tbh it's cheeky of them to ask you.

weirdoboelady · 23/08/2026 20:00

I've read the OP's posts, but not all the replies.

I have two different ways of making this decision, which lead to different answers. Your choice whether you use either or neither!

  1. A seven year old is too much responsibility 24/7. She either comes and joins a kids' club, or she doesn't come. The child themself can be involved in this decision. Looking after a 7 yr old is totally different from looking after teenagers.
  2. The object of the holiday is for that generation of children to see their granny and grandpa again. The 7 yo hasn't met these people, so it doesn't meet the holiday objectives to take them!

My choice would be #1, because it can be explained to the child in simple terms. It would be ridiculous to take her WITHOUT her attending a kids' club. Let her join the other kids in the evening!

A final note - it goes without saying that if you take ANY of the kids, your sibling owes you big time!

And DO CHECK that you could even take the 7yo out of the country without either parent being present!

I hope you've got someone to pass you the smelling salts! That's quite an over-reaction. You're being very dramatic.

yamsam · 23/08/2026 19:59

It would be a hard no from me, and not just because of the seven-year-old stepdaughter. I wouldn’t take any of the three children abroad without their parents.

What if something happened to one of them? An accident, illness, hospital visit, anything like that. Their parents wouldn’t even be in the country to deal with medical decisions, and I’d find that far too stressful and far too much responsibility to take on for someone else’s children.

And with the seven-year-old especially, you’re not even related to her, which adds another layer to it. I just think it’s a huge ask and, frankly, a ridiculous request. I personally wouldn’t agree to it.

AnneLovesGilbert · 23/08/2026 19:57

TY78910 · 23/08/2026 19:55

You either take them all or none at all.

Rightsraptor · 23/08/2026 19:50

I can't get over the 7yo having a mother, a father and a step mother yet none of them are available to look after her?

Definitely don't take her with you whether or not the older ones go.

This!

OnlyUsername · 23/08/2026 19:55

InterIgnis · 23/08/2026 19:50

Yes, their own family. The kid has an entirely different maternal family.

And they've only met her twice! I have cousins who grew up 6 hours away who I have only ever seen at (rare) weddings in 45 years and I barely class them as family.

They don’t want to, and this isn’t their sibling/cousin. They want to spend time with their own family, not provide childcare for OP’s sister’s husband.

Ophy83 · 23/08/2026 19:49

You are doing absolutely nothing wrong saying you are only willing to take the older 2.

The easiest 7 year old in the world can't be left at home if you want to pop out with your DH for an early morning swim or a drink/dinner in the evening. She will need entertaining as she is the only child that age around and can't hang around with the older ones as they won't tolerate it (no teen would, for anything more than a short time each day). That completely changes the holiday for you.

Her parents will have to find alternative arrangements.

HelloUpThere · 23/08/2026 19:49

No absolutely not. I have a 7 year old and you’re right, it will not be the same holiday for you all. And I find it odd that her mum would be happy with that arrangement.
Who’s paying for the extra 3 children to come by the way? If it is your sister then surely she can afford a holiday club for the week instead for the 7 year old. By sister, I mean the girls dad really! It’s not either of your responsibility. I have to work during school holidays and have little family support. So I use paid childcare. Tell them to do the same.
It’s sad that your nieces won’t be happy if they end up missing out because of this. But that’s also not your problem, as much as you love them. That will be your sisters decision. Just firmly say you are happy to take the two older children but that’s it. Up to them if they accept.

ThisHeartySloth · 23/08/2026 19:47

Have they thought of family on her dad’s side looking after the 7 yo? Does she have grandparents on his side for example? I know it’s not your job to sort her childcare, but maybe they need a no from you to make them think more about who they could ask.

Exactly. And "They don't want to" isn't more valid than your no, because you don't want to either.

InterIgnis · 23/08/2026 19:48

Mumtobabyhavoc · 23/08/2026 19:44

I disagree that it's some sort of hardship to have older children help out with younger children, etc. I don't believe they should take on full parental roles, but fgs, my 4y/o changes diapers on younger sibling and helps them get dressed.

They don’t want to, and this isn’t their sibling/cousin. They want to spend time with their own family, not provide childcare for OP’s sister’s husband.

Her DH thinks you are a mug. Don't be.

I'm not of the opinion that relatives outside of the household of a blended family (grandparents/aunts/uncles/cousins) always have to treat their stepgrandchildren or step niece/nephew exactly the same as their biological relatives. They've normally got their own grandparents or aunts or uncles on both sides unless they have lost a parent. There's a family on DH's side where the relatives did this and then they split 3 years later. Much upset. That mum is on her 3rd marriage now, different set of stepkids.
