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?

r/

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.

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. 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. 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.

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?

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 any moment it could escalate to Abbie making false claims against someone and it could ruin lives. It’s not a risk worth taking. No one in your family should be alone with her at any time.

    You’re not giving up on her? You just don’t want to be stuck watching a rebellious pre-teen that’s being encouraged to start problems. You need to be very careful around her now, she could say things and make claims that could cause serious problems in your life. With her mom encouraging this behavior, it wouldn’t surprise me. Try not to be alone with her, watch out for yourself. Have your phone ready to record if you do get stuck alone with her.

    Any babysitting you decide to do is optional. You are allowed to define the terms. 

    Just be kind when explaining why you are avoiding being the only adult present when Abbie is there.  NTA!

    “giving up on abbie”? She’s nothing to you at best and and a malicious actor at worst. Get the mother to babysit or, if you do it, ask for hazard pay.

    Babysitting for a siblings step children is stupid anyway. A complete stranger gets laid with another complete stranger and now they’re somehow entitled to your time?

    It’s really reasonable to back away from a situation where someone’s behavior is so unpredictable and their parent seems more like a problem than a solution, NTA. How do you think the family can better protect themselves without putting everyone in harm’s way?

    NTA, if Abbie’s mom gives her some ideas about how to act around people and what to say then she’ll be accusing said people of some horrible things, I agree with the dad, giving up on her won’t fix her but that his responsibility not yours, he’s the dad he should be working on fixing her, you have the right to stay away as long as it take for Abbie to see that her mom is actually ba

    Nta. Explain your worry about her ability to claim things that have never and would never happen falsely because her mom said to. Did the courts intervene because of the alienation that the mom has perpetraited? Because that is what Dad should be going after full custody with monitored visits for mom only.

    It’s not fair, sure, but life isn’t fair. Her behaviour is out of your league and you’re humble enough to admit it.

    To be alone with her is asking for fake assault to be reported. You’re doing what’s best for you.

    Nta abbie isn’t yours to “give up on” Nick and your sister are the ones who need to continue to do everything they can. You shouldn’t be the one who is having to deal with Abbie’s attitude. Your sister and BIL shouldn’t be allowing Abbie alone with other family members while this is going on incase her mothers manipulation is so strong

    NTA. It isn’t giving up, it is realizing this is not your expertise. This girl could claim molestation, or that someone did drugs in front of her, or was drunk, and ruin someone’s life. No one should be alone with her.

    NTA.. Abbie is an obvious risk. If she can snoop and do her mother’s bidding, what’s going to stop her from fabricating claims against you through her mother’s influence?

    I feel for Nick and your sister, but of all people Nick should understand why and refrain from pointing even the slightest finger at you in regards to “only make things worse.”

    Abbie is treading in dangerous territory and your BIL needs to realize that she could LITERALLY ruin lives if she escalates to lying about what she’s finding or what’s happening to her. Because that’s the next step.

    It’s great that her dad is trying to help, but nothing is going to change unless her mother stops feeding into it.

    Keep yourself safe. Your safety is more important than your BIL’s feelings about his daughter.

    OP, stay strong and just say no. Don’t give in to emotional blackmail. Abby is a weapon being used by her mother and will likely stop at nothing to achieve her objectives. She will say or do anything. Never be in her company without another adult to witness the goings on. Good luck. NTA.

    How disgusting her mother is to weaponise her daughter like this.

    I wouldn’t be alone with Abbie in any way even in other houses, her behaviour is extremely problematic, she could ruin lives with false claims.
    I don’t think your BIL is taking this seriously enough and frankly neither is your sister.
    Your sister needs to protect HER children. If Nick doesn’t sort it out and soon, I would be leaving him if I were your sister.
    Her children are growing up in a household where half the time it’s toxic and in edge, that’s not healthy.

    You’re NTA but your sister and brother still deserve support. This sounds incredibly stressful for them. If someone else watches Abbie can you take the younger kids… is there another family member that can come too?

    It’s not Abbie’s fault she’s being played this way and it’s definitely not your sister’s. Have parented troubled kids (relatives) and it sucks. But don’t put yourself at risk either.

  48. JJdynamite1166 Avatar

    NTA. You’re much better off not having to deal with an 11 year old girl going through puberty, who’s being manipulated by her mom and still dealing with the split. Especially since the ex still is
    In the relationship.
    So why don’t you take a break from the family, say until she gets 16. By then that should’ve passed.
    It’s her issues that her parents have put on her. Not your responsibility to help this young girl out from the manipulation and trauma they’re putting her through. For many tears to come.

    But I get it. YOLO. Do you first.

    Abbie is not your problem. That responsibility belongs to her biological parents. If they can’t get her to behave, the consequences are that no one wants to be around her.

    Stay firm. Adding her chaos to your life isn’t helping Abbie.

  56. tabikat1421 Avatar

    NTA the way Abbies mom is influencing her behavior is ridiculous. It isnt nick and the familys fault that her marriage ended. If OP were to babysit the mom could influence Abbie to say OP touched her and that is so dangerous. If OP were to watch the kids I would say set up cameras in the main spaces like hallway, living/dining rooms, and the kitchen, lock any bedrooms leaving only the main spaces and bathroom open that way if she were to claim anything then they’d have the video to say no I was here while she was there.

    NTA- And I fully believe that any parent who creates alienation and loyalty conflicts for their child is going to hell. This is on Abbie’s mother, not on you.

  58. The-Bullfrog Avatar

    She’s being manipulated and alienated from your family by her mother, which can only be countered by showing her that you’re good people. If they’ve got custody of her this weekend, why are they going out without her? Not the greatest way to help her to feel part of the family, is it?

    “Giving up on Abbie won’t fix anything.”

    1. You’re not giving up on her, you’re just refusing to volunteer as tribute to deal with her shenanigans. 2) HE chose to have Abbie as a step-daughter, you did not. It’s great that he’s not giving up on her (and he shouldn’t), but he also should understand that you didn’t pick this battle; he did. 3) I have seen way too many cases like this where the bad behavior escalates into false allegations: There was the daughter who accused her stepfather of purposely walking in on her to see her naked, the niece who accused her uncle of flashing her, and the daughter who lied and told a mandated reporter that her mother was parentifying her, getting the mother a visit from CPS. You need to protect yourself and your peace. NTA.

    NTA- SA allegations will ruin your life. Stay away from that child at all costs. You can watch the others, but she needs to understand that she is not playing a game with her mother. That her actions and attitude come with a cost.

  61. ghostoftommyknocker Avatar

    I suppose the (very sad) question that needs to be asked is this:

    You’ve mentioned all the work being done to try and stop her from behaving this way, but do any of you know what kind of consequences and punishment would be/are being inflicted on the child by her mother if she does actually stop?

    That is the real issue — what the mother is doing to her child and how it’s going to keep escalating until something terrible happens or the mother is stopped.

    There is nothing you can do except protect yourself. You’re not giving up, you’re setting a boundary. It’s not your job to either work with or give up on the girl. Protecting and saving the child is up to Nick, the courts, the therapists and any child services involvement that’s brought into play.

    You need to tell your sister “I am not risking Abbie accusing me of sexually assaulting her. This not negotiable”

    Because mark my word, she will at some point make remarks that could be interpreted as you being inappropriate with her

    Years ago, an ex of mine was a teacher for students with behavioural problems, and one of his students (grade 2 or 3) informed him that her mother told her to say “he touched me” if he tried to stop for doing something she shouldn’t.

    Don’t risk your life over that child. It’s not worth it

  63. Tasty_Doughnut_9226 Avatar

    Nta you turn around and tell Nick, that you’re not prepared to have some horrible lies told about you and that’s honestly where you are Abbie heading, so you’re not going to put yourself in a situation that makes that possible. Also Abbie needs to realise people aren’t going to stick around for abhorrent behaviour and she needs to be told that. OP won’t sit for you because he doesn’t trust you.

    Pretty sure this is called parental alienation syndrome. As Abbie grows up she will likely turn on her mother. Many of my fellow stepmothers experienced this and it always resulted in the child turning against the parent who was trying to destroy the other parent.

    You can choose not to completely give up on Abbie while also choosing to stay safe. It seems like Abbie’s mom has Abbie looking for evidence to use in a custody battle, and if she doesn’t get real evidence, she might start encouraging Abbie to manufacture some through false accusations. You should avoid being the only adult present when she’s around until this issue is resolved.

    NTA. What happens if Abbie says you did inappropriate things to her? Because this could very much happen. Your sister should probably have a couple of cameras in her house, just in case Abbie starts telling lies that could ruin her life. They could record Abbie snooping too.
