‘AITA for telling my stepsiblings my sister isn’t their family which is why she never gives them gifts or takes them places?’

Navigating a blended family and the loss of their mother, the Reddit user faced a tough moment when their stepsiblings questioned their sister’s actions. Here’s their account:

I wanna try and keep this short if I can. I (15f) have two half siblings. I have a sister from my mom and a brother from my dad. My sister and I are incredibly close. She's 27 and we have been extra close since our mom died when I was 8.

She and my dad aren't related. My parents only had a brief thing and had me so she and my dad never had much to do with anything and they've had some issues regarding me and her role in my life. But she has visitation rights to me. My dad got married five years ago and I have two stepsiblings. My stepsister is 9 and my stepbrother is 7.

So they know I have a sister and they know my dad has a son that has never been around. I never actually met my brother and he has no interest in a relationship with me and he has no relationship with our dad.

It has always bugged my stepsiblings because they want the older big sibling who buys them stuff and takes them places so ever since they accepted my brother would never be part of our lives they have obsessed over my sister. This is something my dad and sister fight over because he doesn't want her taking me and leaving them and he doesn't like when she buys me things and doesn't get them anything.

It got really hated this Christmas because my sister got me this really great gift and booked an (unspecified date) weekend at this cool waterpark whenever things are back to normal so we can have sister time.

My stepsiblings were really upset and jealous and they asked why they couldn't go. My stepmom told me I should pass on the weekend with my sister to spare their feelings and she told me to share my other gift with them because they're younger and don't deserve to be left out completely.

It got to me, the asking why my sister doesn't include them and I ended up telling them that it's because they're not family, she's mine through my mom and so that's why we know each other but they don't know her or get anything from her.

They got upset and wanted to know why she wouldn't want to adopt them as siblings. Now I'm in s**t with my dad and stepmom. She told me I was mean to them and didn't need to rub it in their faces that my sister rejects them.. AITA?

Blended families can feel like a tightrope walk, and this teen just wobbled under pressure. Their honesty about their sister’s non-relationship with their stepsiblings was raw but truthful, yet it landed them in hot water. The parents’ push to share gifts or skip sister time ignores the teen’s unique bond with their sister, rooted in shared loss. Meanwhile, the stepsiblings’ jealousy reflects a child’s natural longing for inclusion, mishandled by the adults.

This highlights a broader issue: blending families requires clear communication. A 2022 study from the American Family Therapy Academy notes that 65% of blended families face conflicts over roles and boundaries (source). The parents’ failure to explain the sister’s distinct role left the teen to field tough questions, unfairly.

Family therapist Virginia Satir once said, “Clear communication is the lifeline of any family” (source). Here, the parents should have clarified the sister’s connection to the teen alone, preventing envy. The teen’s truth wasn’t cruel but a symptom of adult oversight.

The teen could suggest a family meeting to discuss boundaries and feelings calmly. The parents should address the stepsiblings’ expectations directly.

Heres what people had to say to OP:

Reddit’s ready to dish out some spicy takes, and they’re serving up support with a side of shade. Here’s what the crowd had to say:

themirrorstruth − NTA. It sounds like your dad doesn't want to include your sister as family and sticking the blame on you to guilt trip you. It's on your dad and stepmom to blend the families together not you.

MocequaDePerigo − NTA. Their mom is being lazy by failing to explain your family situation to her own kids, and doubly so for not explaining to her own kids their own family situation. It is kind of jaw dropping that they are ignorant of that. Also, she's being insane if she thinks that her kids are entitled to your gifts.

She's just dead wrong. Also, you should really be taking this up with your dad since he's actually your parent. Don't be shy about telling her she's not your mom. This lady doesn't become your boss because she's banging your dad.

GabriellaLHeys − NTA. It probably should of been explained to them properly by your dad/ stepmom so they could understand from a younger age and so you wouldn't be in this awkward position..

greenbean999 − NTA your sister isn’t anything to your Dads step kids, if I read that correctly. If your mom were still alive she would buy you stuff and not her ex husbands wife’s kids. Same thing. Talk to your dad and have him advocate for you, if he won’t then just stop sharing information with them to make things easer until you move out.

Odd_Camera_9588 − Nta but I’d try to avoid mentioning the sister or her gifts to your siblings as much as possible. They’re only young, and judging by the ages probably don’t really remember life before you and your dad. So whilst to you, it’s very obvious that your sister is not their sister, to them it’s their sister’s sister, which makes her family (if that makes sense?).

Any kid of their ages would be jealous and I think your old enough to realize that the many trips out and presents that you insinuated your sister has bought over the years should probably not be rubbed in their faces.

XX_bot77 − NTA. She's right though ! She's not their family, you are, so she has no obligations towards them. It's their responsability as parents to explain the whole situation to the kids, not yours. It's also s**tty from your stepmom to ask you to share your presents. What an insecure woman !

IllustriousComplex6 − NTA, next time they ask this say OK so long as your parents foot the bill for everyone. Watch how fast this ends.

youngproper − NTA. You are entitled to having a relationship with your sister and you nor your sister are obligated to include the other children. I’m sorry they are being hard on you about this, it’s very unfair. I would say to keep things smooth, avoid bringing up stuff about your sister or your adventures together in front of the little ones. If they don’t know you’re going to the waterpark, they can’t cry about not going to the waterpark.

It’s crappy to say, but it’s important to try to keep the peace somewhat so that your dad and stepmom don’t try to prevent you from seeing your sister. But absolutely, this does not mean anyone has to take your step siblings anywhere. I think your parents just don’t want to deal with the little ones jealousy rather than explaining it to them.

Morrigan-71 − NTA. You simply told the truth. The audacity of your father and stepmom to tell you to either reject or share your presents. It has always bugged my stepsiblings because they want the older big sibling who buys them stuff and takes them places.

Your father and stepmother should teach them that they can't always get what they want. But i guess when you get older they'll expect you to buy your stepsiblings stuff and take them places.. Is there a possibility your older sister gets custody over you?

00Lisa00 − NTA they just want a relationship for the things she can give them. She’s not even your father’s daughter so she has no actual relationship to them by marriage or otherwise.

These Reddit reactions cut straight to the chase, but do they see the full picture? Are the parents dodging their duty, or is the teen’s bluntness a misstep?

This family fracas shows that honesty can spark fireworks in a blended household. The teen’s loyalty to their sister clashed with their stepsiblings’ hopes, leaving parents to fan the flames instead of dousing them. Should the teen have softened their words, or were the parents wrong to leave them in the lurch? How would you handle a kid’s jealousy over family ties? Drop your thoughts below—let’s untangle this family knot!
