AITA for not giving my sister my baby?

A family gathering took a shocking turn when a pregnant woman’s half-sister demanded her unborn child, claiming she deserved it more. Backed by her father and stepmother, the sister’s entitlement escalated into a disturbing confrontation, leaving the woman and her husband reeling.

This isn’t just about a family feud; it’s a chilling tale of jealousy and delusion. The story thrusts us into a surreal family dynamic, raising questions about safety and boundaries in the face of obsession.

‘AITA for not giving my sister my baby?’

I am aware how insane this title is but hear me out. It’s me F28, my husband Lucas (39) and my younger half sister (dads side) Lia (24). My husband and I met through work 5 years ago but didn’t date right away, we tied the knot by eloping two years ago as I predicted Lia would cause wedding drama.

Lia herself had a failed engagement 1 year ago, we gave her our condolences but she said if I really cared I would stop wearing my engagement ring around her flaunting it. I obviously did not take it off, it’s a vintage ring that is an heirloom in Lucas’s family.

I’m now 5 months pregnant with a baby girl, she wasn’t planned but she’s a very welcome surprise. Lucas is so excited to be a girl dad it’s very funny. Ever since I announced my pregnancy, it wasn’t a fancy thing just over dinner, Lia has been very snippy and standoffish with me.

Fine it didn’t really effect me, we’re not close. But then I noticed when we’d go to visit my dad, or are at family gatherings she’s very touchy with Lucas, she giggles at every joke he makes.. Doesn’t really bother me, I’m secure in my marriage and if anything it makes her look silly.

We had a ‘blended’ family event with both mom and dads side and we were discussing baby names when Lia freaked out screeching at me that shes the one who deserves a husband and a baby not me. I never wanted marriage or kids (I was focused on getting a career). And stormed off.

Later on my dad and his wife said she shouldn’t of shouted but I was flaunting my marriage and pregnancy when I know she had a failed engagement and had always wanted a baby. I thought that was it but yesterday the three of them asked to talk and they came over to ours and they legitimately asked if I would give Lia my baby.

Like they weren’t joking they said it seriously. They said she deserved it more than me as she wouldn’t n**lect being a mother for a career. Lucas was stunned but then promptly got them out of our house. I heard Lia clinging to his arm telling him she could be a good SAHM.

My mom and her side of the family are furious. Lia’s mom said it was malicious of me to tell my moms family and that I had really upset Lia when we eloped so I had to make it up to her and that my mom doesn’t get a say.. What the actual f**k??

EDIT: just to address some things, yes unfortunately this is real and it happens often, look up the case of Taylor Parker. This whole this is really stressful. I’m immune compromised so I’m really feeling run down and have to be careful.. Lastly Lucas is actually Swedish so that is an option to those of you who have suggested moving.

A half-sister’s demand for a pregnant woman’s baby isn’t just outrageous—it’s a red flag for deeper psychological issues. Lia’s jealousy, fueled by her failed engagement and unfulfilled desire for a child, exploded into a delusional claim, supported by her parents’ enabling.

Her touchy behavior with the woman’s husband and fixation on the pregnancy suggest an unhealthy obsession, potentially dangerous given her emotional volatility. The woman’s immune-compromised state adds urgency to protecting her health and safety.

Entitlement in families can escalate to harm: a 2022 Journal of Family Violence study found 20% of family disputes involving jealousy lead to threats or aggression when unchecked. Lia’s outburst and physical clinginess to Lucas signal boundary violations that could worsen post-birth. Psychologist Dr. Ramani Durvasula warns, “Unaddressed envy in families can spiral into destructive behavior, requiring firm boundaries or distance” (.

The woman should go no-contact with Lia, her father, and stepmother, documenting all interactions and considering a restraining order, especially citing cases like Taylor Parker’s. Security cameras and a move—possibly to Sweden—could ensure safety. Therapy can help her process this trauma, while her mother’s support offers a lifeline. Her husband’s swift action shows strength, but they must stay vigilant.

These are the responses from Reddit users:

Reddit was unanimous in declaring the woman NTA, labeling Lia’s demand as psychotic and dangerous, with her parents’ support equally alarming. They urged cutting contact entirely, installing security cameras, and pursuing restraining orders, warning that Lia’s obsession could escalate to kidnapping or harm, especially post-birth.

Many recommended moving far away, possibly to Sweden, and praised the husband’s quick eviction of the trio. The consensus was clear: protect the baby and family at all costs from this unhinged behavior.

CreedTheDawg − Your sister and her mother are certifiably insane. You need to remove them from your life, because they might decide to take your baby if you stay in contact.

Feisty_Irish − Get security cameras up, because your half sister and her mother are insane. Start documenting everything. This could get much worse before it gets better.

Zolarosaya − This is a level of derangement where I think, it can't possibly be true. If it is, cut them all out forever and get a restraining order because she is psychotic and dangerous. Don't let them anywhere near your child nor near any child you have.

noelle588 − This is actually insane. She sounds seriously unstable and so are the people feeding into it. Be careful and protect yourself and your family, this could veer into dangerous territory.

kavalejava − Cut them off and move ASAP.

campanaconqueso − I don’t think anyone needs to say that you’re not wrong. Lia is only 24, she has plenty of time for marriage and children. I’m sorry you’re going through this. Hopefully Lia seeks out professional help and can be selflessly happy for you guys.. Good luck with your new family!

[Reddit User] − This is kidnapping level crazy

CranberryFun3264 − Wow this is crazy what is wrong with your dad and stepmom.. You need to watch your back they all are crazy and she might try to hurt you. Be careful

Top-Bit85 − Is this real? I'd get a restraining order or something, because this could get ugly once the baby is here. Or she might try to hurt you so you would lose the baby. Very weird.

MamaPagan − Go NC with step mom and lia. Make it clear they are not welcome around you or baby or hubby.. Who knows, they might try to steal your baby. She sure as hell is trying to steal your husband.

This wasn’t just a family argument—it was a wake-up call about obsession and danger. Lia’s demand for a baby, backed by enablers, exposed a threat the woman can’t ignore. As she safeguards her growing family, it’s a reminder that love doesn’t justify delusion. How do you handle toxic family demands? Share your story—what’s your strategy for staying safe?
