AITAH for not babysitting for my sister on prom night?

At the heart of a night meant for celebration and youthful joy, a sophomore’s anticipation of prom is shadowed by unexpected sacrifice. Invited by a senior friend, she was ready to embrace the magic of the evening, only to have her hopes dimmed by family needs and unyielding responsibilities.

Caught between her own dreams and her half sister’s chance to reclaim a lost moment, she faced a quiet heartache, giving up her night to care for a baby, a choice wrapped in love yet tinged with unspoken longing. The echoes of that decision linger, a tender reminder of the cost of family loyalty and the silent weight of dreams deferred.

AITAH for not babysitting for my sister on prom night?

Our school’s prom was a few weeks ago. Even though I’m a sophomore I got to go to prom this year because one of my best friends is a senior and she invited me to go with the rest of our friends.

My half sister was also going to go. She couldn’t go to her junior prom because she was pregnant at the time. This year her boyfriend’s parents were supposed to watch her baby that night, but his dad was having chest pains so his mom had to take him to the hospital.

Our mom couldn’t watch her baby because she works nights. So they were trying to find someone else to watch the baby.

They tried calling a bunch of people to babysit, but couldn’t find anyone else, so they asked me to skip the prom and babysit so my sister could still go. My sister offered to pay me to babysit and for my dress and share of the limo eventually.

I didn’t need the money though and I really wanted to go with my friends.

It’s almost been a month since and she’s still keeps bringing it up and won’t leave me alone about it. My mom also said she’s disappointed in me for not helping out my sister since it was her last chance to go to prom and I still have two more chances to go.

I don’t think that’s fair though because it was still my only chance to go to prom with my friends who were seniors.

Here’s how people reacted:

NTA. It’s tough being a parent and even more if you’re a teen parent, but if she made that choice then she needs to understand she will have to give up certain experiences. Now if you lived somewhere where she didn’t have access to abortion and she didn’t want to be pregnant and a mom than I’d have more sympathy, but that time has passed and she’s a parent now. If you wanted to be nice you could offer to babysit so she and her boyfriend/baby daddy could get dressed up and go out to a nice dinner so she could wear her dress, but only do that if you want to. Don’t let them try to guilt you.

NTA. When your sister decided to become a parent and keep her baby, she took on the responsibilities of that role. I know she’s too young to be a mother, but she chose that instead of abortion or adoption. Baby comes first. Other people do not owe her childcare. It’s a hard place to be and I feel for her but you did nothing wrong.

Also your sister fucked up her own first prom. That’s not on you or anyone else to fix.

**edit: please see comment from u/ka-ka-ka-katie1123 below as I definitely dropped the ball here in regards to the abortion/adoption comment**

As a loving sister and aunt. YTA. She lost her last opportunity to go to prom. You were privileged to go early and will still have two opportunities. I wouldn’t forgive you for the lack of empathy you showed.

Edit – You guys can down vote and disagree all you want. At the end of the day, she was selfish vs being selfless. And the amount OP would have lost by not going is significantly less than what her sister would have gained.

Her baby, her problem. I have no problem with younger mothers, some of them are absolutely amazing, but this is a deal you make when you get pregnant. You’re going to miss out on stuff, for years, and you have to deal with it. You didn’t have a child young, so you shouldn’t have to sacrifice your experiences for her sake.

Your mother should have either stayed out of it or used it as a learning opportunity for your sister. This is the reality of having a child.

Where are your father and hers? Could neither have them babysat? She and the father of her child are now parents and you don’t get to do what you want when you want.

Good on you for standing up for yourself. You are NTA.

Remember that “No” is a complete sentence. If they bring it up again, walk away. Tell your mom that you’re disappointed in her for raising a kid who got pregnant in high school.

NTA.

Half-sister can’t blame OP for missing prom. Her responsibility to her child should be *her first priority*. And sacrifice is part of a parent’s job description.

This goes double for single parents.

Tell your mum and your sis that she decided to have the baby not you so it isnt your problem if you dont want to baby sis as its not your baby and she should have thought about it before she had it
CampClear

NTA, when you become a parent, you have to put the baby first and that means sometimes missing out on things. It’s not your responsibility, it’s all on your sister.

Absolutely not! Tell them to knock it off. It’s not your problem she couldn’t go to her prom and her kid is not your responsibility!

This is the reality of being a parent. Sometimes you have to give up doing something you want to care for your child.

NTA. Parent’s responsibility to take care of their own child, even if it means missing prom…twice.

Would it have been nice for you to babysit? Yes.

Were you under any obligation to do so? No.

Conclusion

The original poster (OP) feels conflicted because they prioritized their commitment to their friends and their own desire to attend prom over their sister’s last-chance opportunity to go, leading to ongoing friction with their sister and disappointment from their mother.

Given the OP’s desire to maintain friendships versus the family expectation of sacrifice for a sibling’s special event, is it reasonable for the sister and mother to continue pressuring the OP when the OP had already made a significant sacrifice by attending prom with senior friends, or should the family accept the OP’s decision as a valid prioritization of their own experience?
