17 Y.O. Refuses to Consider Her Dad's Baby with His 23 Y.O. Girlfriend as Her Sibling Despite Her Mom's Support
“My dad overheard and said I can’t resent an unborn child.”
A 17-year-old refused to treat her dad’s new baby as her sibling, and the reason is messy, personal, and way more uncomfortable than “blended family drama” sounds on paper.
Her dad and his 23-year-old girlfriend, Kayla, have landed in a situation where everyone is acting like everything is normal. Kayla is the girlfriend, but she’s also younger than OP’s oldest sibling, and OP’s mom seems totally fine with the whole setup. Meanwhile, OP is stuck watching Kayla and her dad move forward like she’s supposed to just absorb a pregnant surprise into her life.
The conflict is less about a baby, more about control, boundaries, and whether OP is being pushed to accept a role she never agreed to.

That’s when Kayla’s pregnancy announcement hit OP like a betrayal, not a celebration, and suddenly the house felt like it was changing without her say-so.
Addressing these feelings requires open communication and emotional support.
The mother seems to be completely fine with the arrangement they have.

It's unsettling that they are both completely fine with it.

Why is Kayla responsible for these issues?

It almost sounds like Kayla is being groomed.

“Either you’re in or you’re out.”

No parent should make their children go through something like this.

“You'd be an asshole for not recognizing this new baby as a sibling...”
Reddit: r/AmItheAhole
OP can't change that, no matter how much she tries.

“Be aware that Kayla is likely being exploited in this situation as well.”

It's strange that OP's dad impregnated a 23-year-old.

OP revealed her mom and dad's ages after this user asked.

“They can't force you to have anything to do with anyone once you move out and are independent.”
Reddit: r/AmItheAhole
OP can’t square it, because Kayla is effectively being treated like a steady part of the family while OP’s siblings are barely invested and her mom is acting like nothing is wrong.
Redditers clock the age gap fast, pointing out Kayla is younger than OP’s oldest sibling, and that detail makes everything feel more unsettling than “new girlfriend energy.”
Then the comments flip to the real question, why OP is being told she has to either accept Kayla as part of the family or get treated like she’s the problem.
OP shouldn't feel forced to consider Kayla as a mom, but the child she will have will be her sibling, whether she likes it or not. She shouldn't hate her unborn sibling because of circumstances that are out of their control.

The situation surrounding a 17-year-old's refusal to accept her father's new baby with his 23-year-old girlfriend highlights the complexities of blended family dynamics. The teenager's struggle reflects a broader issue of acceptance and emotional adjustment that often accompanies significant family changes. Open communication is key in these scenarios. Parents must strive to foster an environment where feelings can be expressed without judgment. When children perceive themselves as valued members of the family unit, they are more inclined to embrace new relationships, however challenging they may be initially. It is crucial for parents to create inclusive dynamics to help ease the transition and mitigate any potential resentment.
The family dinner did not end well, because OP is not the one who agreed to rewrite what “sibling” means.
