AITA For refusing to babysit for my brother and SIL after they previously told me they don’t trust me

He lives a life unapologetically his own—embracing nights out, music festivals, and a bachelor’s freedom while thriving in a high-powered corporate career. Yet beneath the surface of his confident exterior lies a quiet sting, born from the cold dismissal of his family’s trust. When his sister-in-law outright declared she would never leave her child in his care, it wasn’t just a refusal—it was a blow to his sense of worth and belonging.

Torn between his chosen lifestyle and the yearning for familial acceptance, he grapples with the invisible barrier that separates him from his brother’s growing family. It’s a story of love, judgment, and the painful complexities of being misunderstood by those closest to you.

AITA For refusing to babysit for my brother and SIL after they previously told me they don't trust me

I (28M) have an older brother (31M) and SIL (30F) who have a 3-year old son and SIL is about 7-months pregnant with their second child. I am a single man in my 20s and live by myself.

As such, I live a fairly typical bachelor lifestyle. I enjoy going out to bars and clubs, in the past I have attended music festivals and dabbled in drug use, and I do not apologize for it.

It’s the way I am choosing to live my life right now. But I am also working full-time for a Fortune 500 company and making well over 6-figures. All in all, I like to think that I have my stuff together pretty well for a person my age.

When my brother and SIL had their first kid, SIL pretty much told me in no uncertain terms that she would never trust me to watch her son by myself. She told this to me completely on her own and when I asked my brother about it, he pretty much just sided with her and shrugged.

Now, I admit that some aspects of my lifestyle are not kid-friendly. But I also understand there is a time and a place for everything and I would never do anything to put my nephew in any compromised situation.

I have never pressed the topic with SIL or my brother and until recently it has never been a problem.

A few weeks ago my brother called me in the middle of the night and asked if I could watch their son. SIL was having stomach pains and they needed to go to the hospital but they had no one else to watch their son.

SIL’s parents were quarantined after Covid exposure, and every other option they had couldn’t do it. I was literally a last resort. I asked if SIL was ok with it, and my brother said she didn’t know he was asking me and he was desperate.

I told him the only way I would be ok with it was if SIL asked me herself because I didn’t want to cause an issue. My brother told me they didn’t have time and they would drop off my nephew on the way to the hospital in an hour.

When they got to my apartment I went down to meet them and SIL saw me and recognized where they were and started screaming at my brother. She started yelling questions at me like whether or not I have drugs on the counter, or if I have a girl up there with me.

So I told my brother I was sorry, but this wasn’t going to work. I told him I love him and hope everything works out and I told SIL the same but she ignored me and told my brother to take her to the hospital.

Everything at the hospital ended up being OK and SIL and baby are healthy. She wasn’t going into early labor and they were back home the next day. However, my brother called me after that and said I was a huge asshole for not helping.

I said it wasn’t really my decision as SIL made it pretty clear in the moment that she didn’t want her son staying with me. He said I should have just taken my nephew as SIL was in no condition to make a rational decision.

My mom called me the other day and said I should apologize to my brother and SIL for what I did, but I don’t think I was even in the wrong. Was I an asshole for not helping them?

Here’s how people reacted:

NAH. You’re all upset. It was a crazy panicked moment for everybody. You’re a responsible brother and your nephew will eventually beg and plead to stay with you, have you come over, etc. The SIL is a new mom, going to hospital. Please give her some room to make mistakes and learn from experience. Doesn’t mean she’s right, but that didn’t make her an TA. Neither is your brother. He trusts you to help in his emergency. His wife was in pain and scared. Nobody is a bad guy in this scenario. But hopefully you can be patient and let them grow up as parents. They will, and they’re still your family. Those kids are going to love you so much as fun uncle. Just let them work their stress out and don’t take it personally.

NTA – she might not have been rational in that moment, but neither was your brother. Having her screaming and fighting to (in her view) protect her child was not going to end with her going to the hospital any sooner.

Going forward, I think it might be worth trying to talk to your brother and SIL in terms of the impression she has of you. Have you had drugs lying around your house before? Was she asking about a girl as a moral judgment or a covid concern? Where did she get her idea of your place as a den of iniquity?

You’re 100% entitled to your lifestyle choices, but something is going on in the disconnect between how you describe things and her attitude/reaction.

NTA. However unpopular opinion i would apologize to the SIL ONLY! You did absolutely nothing wrong. She told you she didn’t want you to watch her kids. You told your brother you would ONLY if she approved. Your brother is the ass. And I would tell her that. Say he called me up and I told him I would only with your approval, he said you gave it. I didn’t mean to stress you out more.

You’re brother owes you and his wife an apology. She was already experiencing pain that ended in her ending up in the hospital. He added extra stress to both of you and needs to apologize for it.

NTA. Unfortunatley no matter what you did it would have ended badly. But let’s play out the other scenario. You take the child even though the mother is screaming in the background. Later, an angry mother comes and takes the child and you are never let within a mile of her or her children again. Also, she is extremely angry with your brother for leaving her child with you against her wishes. I’d say you chose the correct option.

If she, in her state of mind, had enough capacity to insist NO and to question whether you had drugs or a girl (both of which are none of her business), then she was in her right mind enough that her demand of NO should have been respected. This should be said to anyone who tries to say you’re wrong. SOMEONE should be asking SIL why she had to be an asshole, not asking YOU.

NTA, and don’t let them tell you otherwise.

SIL has some heavy emotional issues. Your brother knows it and I think he’s so embarrassed that he has to to blame you.

So many ppl (parents and grandparents too) use drugs recreationally and responsibly in the modern world.

NTA, and I understand why you wouldn’t want to put yourself at risk to this wackado should anything (even minor) go wrong with your nephew under your care

cdifl

NTA.

You are absolutely not the AH in this situation, and you did the right thing.

They can’t year you like crap at the same time as they are asking a huge favor of you. And you should absolutely not take a child against any parent’s wishes.

It’s not ideal, but you can take a kid with you to the hospital. This is not the first time this type of situation arose.

[deleted]

NTA, your Mom is though – what exactly did she want you to do? Ignore your SIL screaming and just reach into the car and grab your nephew? It seems pretty clear that SIL had no intention of leaving him with you so how could you help?
Perhaps your Mom can explain how you were supposed to help and then you can decide if you should apologise (spoiler you should not!).
idrow1

NTA – I got really mad on your behalf when I got to the part where your mom called you and told you to apologize. That takes some giant balls. Do NOT apologize.

Your brother needs to sort this out with his wife. If he wants to be mad at anyone, he should be mad at her. He’s just taking it out on you because he can’t take it out on her.

chadbelles101

NTA – you handled that like an adult (unlike your brother). You didn’t want to trick your SIL and are taking responsibility and understanding her position. Your bro put you in a bad spot and wanted to trick his wife which isn’t fair to anyone. You did the right thing and hopefully she acknowledges that you didn’t want to trick her
jkl545454

NTA – you would have helped if you had the mother’s approval. SIL is the asshole.

Edit to add: many of you have made great points! I’m seeing now that maybe the brother is the asshole… SIL was clear in that she never wanted her child watched by OP. Brother didn’t respect her wishes, or OP’s request to ask SIL first.

srhfay

Nta. What exactly does your mother want you to apologize for? Your SIL has made it very clear she does not want you to watch your nephew all by yourself. Her husband ignored her decision by asking you to babysit. This sounds like an issue between husband and wife and not something you have to be involved in
JabbaInBlueJeans

Nothing about this makes sense. How could your SIL not know where her son was being dropped off? Did your brother keep the destination a secret until they got to your place?

NTA, but something about this story doesn’t add up.

NTA, I personally believe you went about this the right way. You were willing to help, you knew SIL wouldn’t so you asked for her permission. I don’t think you owe anyone an apology.
dreadedbeedee

NTA.
Your brother is for putting you in that situation. You tried to ensure SIL was on board and she wasn’t.
You are entitled to live your life as you wish.
Chairmanca93

NTA. Thats insane. You literally were going to get screamed at and have been the bad guy no matter what you did. That’s not fair to you at all.

NTA

Your SIL made it clear that you aren’t welcome as a caregiver. Let them now live with her choices.

Conclusion

The original poster (OP) faced an emergency situation where his brother and sister-in-law needed urgent childcare, directly contradicting the sister-in-law’s long-standing distrust of his lifestyle. The OP prioritized respecting the sister-in-law’s explicit boundary, even under duress, leading to the immediate conflict being resolved by the family leaving without leaving the child in his care. The central conflict is the OP’s assertion of boundaries and self-respect versus the brother’s expectation of unconditional support during a crisis.

Was the OP an antagonist for refusing to watch his nephew when the primary caregiver explicitly rejected the arrangement in that moment, or did he correctly uphold established relational boundaries? Should immediate familial need override prior stated comfort levels in a genuine emergency?
