AITA for refusing to see my parents new baby as my sibling?
A 17-year-old girl drew a hard line: the baby on the way isn’t her sibling, and the 23-year-old carrying it will never be family. Dad’s girlfriend, Kayla, already lives in the family home—cleaning rooms, handing out £60 weekly, chauffeuring teens. When the girl said she’ll vanish at 18, tears flowed and rides stopped. The twist? Mom and dad are still married, just openly dating others.
The setup screams chaos. Social media recoils at the age gap, the open marriage, the domestic-labor dynamic. Everyone agrees the teen owes no bond—but some warn: reject the baby, lose the perks. One year until freedom; the countdown just got louder.
Parents stayed hitched but opened the door to outside romance.
Everyone except the eldest warmed to Kayla—parents pushed hardest.
Pregnancy news dropped; the teen stayed ice-cold.
Kayla overheard and crumbled.
Dad piled on; perks vanished.
This isn’t a blended family—it’s a social experiment gone sideways. Open marriage, live-in girlfriend younger than half the kids, domestic duties assigned without consent. The teen’s rejection is a rational boundary in an irrational setup.
Family therapist Dr. Esther Perel, expert on modern relationships, notes, “Non-monogamy requires explicit agreements; children cannot consent to the terms.” Kayla’s labor—cleaning, driving, allowance—creates a power imbalance disguised as generosity. Refusing the “sibling” label protects emotional autonomy.
Practical moves: return the money, find alternate rides, document everything before 18. Therapy (solo) could unpack the weirdness without parental spin. Kayla isn’t the villain, but she’s complicit in a dynamic that exploits her youth. The baby arrives blameless—acknowledge biology, skip the bond. Freedom at 18 is the finish line; plan the exit now.
Here’s the comments of Reddit users:

A household built on open doors and closed logic just slammed one shut. The teen spoke her limit; the adults scrambled. Commenters call the dynamic predatory and praise the boundary. Biology may link the baby, but love isn’t mandatory. One year left—would you pocket the cash and play nice, or ditch the perks and sprint to 18?
