To think it's unreasonable to charge family for one off babysitting

Just cancel.

Have you said you'll pay her by returning the favour sometime?

Bit mean. I assume niece is a kid still? Then it means a lot to her to earn something and you’d be paying a lot more otherwise so it’s not like you’re doing her a favour by letting her look after your kids!. Grinch is next month!

Cancel. Just text her, 'Never mind, we've made other arrangements.'

Unless I’m completely misunderstanding then of course you should pay her? Coming over for a sleepover and spending time with you as a family is completely different to sitting there on her own watching a film while you and your husband are out and your children are asleep!
It sounds like you’re getting a free babysitter but you’re dressing it up as answering your niece’s request for a sleepover.

@Sparklybanana think you misread my post. I didn't say I was doing her a favour.

Actually I think it’s fair to pay her. If she’s old enough to be responsible for them while you’re out, then surely she’s old enough not to be hugely excited by the prospect of a sleepover being suitable recompense?

If you’re not happy paying her then cancel and pay a regular sitter.

I’d be more than happy to have a niece who was available and prepared to babysit (and be paid for her time)!

I don’t pay friends to babysit in a reciprocal agreement, and wouldn’t charge my brother if he had kids. But if friends’ teens babysit then I’d definitely pay, there’s no reciprocal arrangement to be made.

You definitely need to pay her - she is doing you a favour regardless of whether she then sleeps over and has lunch the next day. How much is it going to cost you for goodness sake - £10?!

I would pay and provide pizza money. I don't understand why you wouldn't.

This is exactly it.

You should pay her. You've not invited her for a nice family night and sleepover. You want her to babysit. That deserves payment.

Is niece a teen? I do think you should pay her, even if it’s not as much as you would pay an adult babysitter. When I was a teenager I used to get a ten or twenty for watching my sister or cousins for a night.

@Wheresthesandman yes you have misunderstood. She'll be having dinner with all of us. DH and I are going out for 2-3 hours and she can watch film with DC. Will put them to bed when I am back. Plan was to all go to Christmas fair the next day. Niece is teenager, my DC are younger.

I think it's reasonable to pay a child to babysit. We paid our niece when she babysat a couple of years ago. £10 for the evening plus some sweets we got in for her. I think it is normal to pay kids to babysit and your sister's earning as not relevant here, it's about what your niece earns.

Yeah another vote for paying her. Coming over for dinner and hanging out with family watching a movie is very different than babysitting young kids and then sitting watching a film on your own. YABU.

What niece’s mum earns is irrelevant to what she should be paid, or whether she should be paid!

I think that just helping out between families is lovely, but it should be part of all supporting each other. How do you support niece in return? Taking her to a Xmas fair is a bit shit for someone old enough to babysit! I mean, it’s a fun trip out and as she’s with family she’ll enjoy it - but it’s not a treat.

She’s your babysitter - pay her!

I pay my adult stepdaughters when they babysit my younger child. They always say there’s no need, and I appreciate that. But I still think it’s right to pay. (They don’t live with me, so they are using their time)

Yeah, I still think you should pay her.

Hmm. if it was an adult I would agree, but by the sounds of she's a teenager so I would expect to pay, especially as I had asked her to babysit, not just her volunteering to help you out of an unexpected tight spot.

Oh just saw your update. Less bad but I'd still lean towards paying her.

I think it’s an issue of responsibility.

When your DH and you are in the house she’s simply a cousin visiting but when you leave her with your children you’re expecting her to take responsibility and be the adult in charge- this deserves paying.

It’s totally different if it were you/your sis/mother/SIL or another adult family member then it would BU to pay or them to expect payment but for a teenager yes she should be paid, family or not!

And even if - ESPECIALLY IF! - she’s doing it for free, yes of course you should pay for her bloody bus fare!

Yeah I think you should pay her too.

If your niece is under 16 I wouldn't be getting her to babysit as she is legally under the age of responsibility.

I think your sister has been angling for you to provide a regular babysitting job for DN!
