Divorce can be really tough on kids, especially when one parent tries to turn the kids against the other parent.

What would you do if you were asked to babysit a child that was known to be a snoop, spy and troublemaker? Would you say yes because you know your sibling really needs a babysitter, or would you say no and opt out of the drama?

In today’s story, one man who used to be the “fun uncle” no longer wants to babysit his sister’s step-daughter.

Read the whole story to find out why.

AITA for refusing to babysit for my sister because I don’t want her stepdaughter in my house or to be on my own with her?

My sister (30s) has been married to Nick (30s) for 6.5 years.

Nick has an 11 year old daughter Abbie from his first marriage and my sister and Nick have two bio kids together. Nick shares custody of Abbie with his ex wife.

For a while things were okay. Everyone in our family got along with Nick and adored Abbie.

But then Abbie’s mom got divorced again.

Things changed when Abbie’s mom’s second marriage ended five years ago.

After that the woman became a nightmare for my sister and Nick and she was doing her very best to turn Abbie against my sister and our family and later her younger siblings.

For over a year now they’ve had a problem with Abbie snooping in private areas for her mom and sending photos and giving info to her mom.

Abbie has really become her mom’s spy.

Nick and my sister had to start locking their bedroom door during the daytime.

They were locking up medications extra tight because even those Abbie’s mom wanted proof of.

Abbie was doing the same snooping at other houses to like my parents, my other sister and my aunt’s houses.

Abbie’s whole personality around us has changed too.

It’s not just that Abbie’s growing up.

I know she’s at an age where that stuff happens anyway but she’s just so rude and around Nick’s family she hasn’t changed.

She’s outright denying we’re her family now and she claims she’s an only child and she only has cousins from her mom and dad even though when she was younger she claimed my other siblings kids as cousins too.

And I (20s) was the fun uncle but she doesn’t see me that way anymore. Not only the fun part but the uncle part too.

He really doesn’t want to deal with all of Abbie’s drama.

I’m not dealing with that alone and I’m certainly not watching an 11 year old like she’s 1 and ignoring the other kids because there’s a risk she’ll snoop around my house the second my back is turned.

This is something Nick has brought to court and I acknowledge that he’s trying.

They have Abbie in therapy too and she’s faced consequences for snooping.

But she gets encouraged by her mom, and rewarded for it, so why would she stop?

He told his sister why he’s not willing to babysit.

My sister wanted me to babysit the kids this weekend for several hours and I didn’t have plans but I said no. This weekend they have Abbie and I’m not doing that.

My sister offered to let me stay at their house if that would work out better.

But I told her that would still mean having to deal with Abbie’s attitude/behavior.

She understood but Nick didn’t and he told me giving up on Abbie won’t fix anything and that I’m going to make things worse.

AITA?

At least his sister understands why he doesn’t want to babysit. No is a complete sentence after all.

Let’s see how Reddit reacted to this story.

Abbie could tell a big lie.

Her mom might encourage her to lie.

He really needs to tell his sister why it could be very bad if he agreed to babysit.
