AIBU for giving my step-niece less than my nieces for 17th birthday?

It’s not up to an aunt to implement equal treatment.

She got the step-niece some nice gifts, that’s more than enough.

I don't think it strongly suggests that at all, I get strong CF vibes from him so to me I strongly suspect that he doesn't.

I also disagree that most parents in blended families work hard to make sure the children feel the same, this has not been my experience at all.

It might be projecting the worst case scenario but on your side you're projecting that this man has done everything to treat them equally and projecting the worst onto the OP.

But she didn’t treat her “kindly” in the same way she treated the others, that’s the whole point. £100 vs £1000 isn’t a small difference. It’s a statement. And it’s a statement that lands very differently when the child has been part of the family for eight years.

And the “she gave the nieces £1000 seven years ago, she couldn’t have known she’d have a step‑niece later” argument doesn’t really hold water. Nobody is saying she should have magically predicted the future. The issue isn’t the past, it’s the present.

Right now, today, she has:

• two nieces who received £1000 at 17
• one step‑niece who received £50 at 17

And yes, of course the step‑niece has other family. (As do the bio nieces - their bio mum and family are still around). But that doesn’t erase the fact she’s been part of this family for nearly a decade. Families don’t operate on strict “bio‑side vs step‑side” accounting. If they did, blended families would never function.

The OP is absolutely free to gift however she wants, nobody is disputing that. But she also can’t pretend that:

• the difference won’t be noticed
• the brother won’t feel hurt
• the step‑niece won’t feel second‑tier
• the family dynamic won’t shift

And honestly, the idea that a child who has lived in the family for eight years should be treated as “someone else’s responsibility” because she has a biological mother and father is a pretty cold take. Most people don’t run their families like that.

This isn’t about demanding equal gifts. It’s about acknowledging the emotional reality of giving two girls £1000 and the third £50.

The message is loud and clear, whether anyone intended it or not.

The step-niece was 9/10 yo when OP’s niece got the driving lessons money.

I doubt it would have registered with the step-niece at that age. Why do you think it would have landed badly with step-niece?

If anyone has been telling step-niece that she can expect £1000 from a step-aunt when she turns 17, then that person is in the wrong, not OP.

They are different. Two are her nieces, one isn’t.

That’s a facetious argument. In law and every other walk of life an adopted child is recognised as having equal standing to a biological child. They also, by virtue of adoption, do not have fathers they spend every other weekends with who can pay for their driving lessons.

The birthday girl has only been in OP’s life for 8 years. 7 years ago she gave her blood related nieces, with whom she had a 17 year relationship with, a gift.

Comparing that relationship on any level with STEP children who have another parent and family, who live part-time with that parent, who are funded by child maintenance payments etc via that parent is frankly nuts. As is suggesting any equivalency between that stepchild arrangement and a fictitious adopted child.

FFS. The idiots on this thread are mind blowing.

Treading them DIFFERENTLY is the key message.

A £100 gift is very right and very kind.

A lot of people don’t spend that much on a bio niece.

That’s fine for your family dynamic, but it’s not a universal truth. Plenty of blended families do operate as one unit, especially after eight years of living together, sharing holidays, birthdays, milestones, and day‑to‑day life. It’s not “emulating a nuclear family,” it’s simply treating the child who lives in your home as part of your family.

And crucially, this isn’t about titles. It’s about belonging.

Whether you personally would call yourself an aunt is irrelevant. The stepniece has been part of this family for eight years. They celebrate together, they visit each other, they have a relationship. So of course the brother hoped she’d be treated the same. That’s not “bitching,” that’s a parent trying to protect his child from feeling second‑tier.

Your experience with your brother’s short‑term stepchild doesn’t map onto this situation. A few years is very different from nearly a decade, and every blended family works differently.

No one is saying the aunt must treat the stepniece identically, she’s free to gift however she likes. But she also can’t pretend the disparity won’t land painfully for a 17‑year‑old who’s been part of the family for most of her life.

Families aren’t one‑size‑fits‑all. Just because you wouldn’t take on an aunt role doesn’t mean it’s “weird” that others do.

Eh? I think we agree. I was replying to the poster who said ‘Why would he buy gifts for kids he has no connection too?’ and clicked quote on your post instead of hers.

Are you one of those blood relatives obsessed people? (With some royal blood presumably, lol).

I disapprove of treating step children differently. It’s not kind and it’s not right.

If you’d actually read the thread properly, the value of the gift was over £100 and the birthday girl was extremely appreciative. If it “sends a message” that she’s different from OP’s actual biological nieces that’s because she is - it’s a different relationship and a different bond. Yet OP was still very generous and thoughtful despite this.

Thinking anyone is entitled to £1000 of someone else’s money and expecting your sister to bankroll your stepchild’s driving lessons is the most grasping, grabby thing I’ve ever read.

Jeez. Well, of course - that’s the point of my original and sarcastic comment? Perhaps I should have added a /s or some sort of emoji for you as you clearly missed it.

But to clarify: There should be no expectation of the step niece’s father spending [considerable or any amounts of] money on gifts for his daughter’s step siblings - it is nuts. By by the same logic, there should be even LESS expectation of OP buying gifts for her nieces’s step siblings at all. She is even further removed - that she buys a gift at all is generous. There should be no expectation of £1000 contributions to driving lessons for an unrelated child.

OP, if your brother adopted children after having biological children, would you treat them differently too?

So treating someone like family means they should have £1,000 spent on them?

She is part of his family. He treats her like family. You did not. Of course it upset him.

OP has treated her kindly. She got her gifts to the value of £100.

7 years ago, OP gave her nieces £1000 for driving lessons. I don’t think it’s reasonable to expect OP to have thought that in 7 years time she would need to give the same to a step-niece for driving lessons. There should be other people in the step-niece’s life that want to give her that gift, like family on her mum and dad’s side. All the gifts don’t need to come from the step-dad’s side.

No, the idea that blended families must emulate nuclear ones is weird to me, and not something I encounter outside of Mumsnet.

My brother had a stepchild for a few years. I wasn’t his aunt, and our parents were not his grandparents. My brother didn’t ever expect us to take on those roles, let alone bitch because a gift wasn’t deemed good enough.

So he can save the money and use it for driving lessons for his daughters.

Adoption isn’t the benchmark for whether a child deserves to be treated kindly by extended family. Most blended families don’t go through formal adoption, it’s expensive, complicated, and often unnecessary when both households are stable. It doesn’t make the child any less part of her father’s day‑to‑day family.

And the brother expecting his sister to include his stepdaughter isn’t “cheeky.” It’s normal. He’s been raising her for eight years. She lives in his home. He’s her parental figure. That’s what matters.

If anything, the fact he did hope she’d be treated the same strongly suggests he does treat her equally himself. Parents who sideline stepchildren don’t usually fight their corner with extended family.

Saying “he hasn’t adopted her so she doesn’t count” is a pretty harsh stance. Families are built through relationships, not paperwork. The aunt is free to give whatever she wants, but she can’t pretend the disparity won’t hurt a 17‑year‑old who’s been part of the family for nearly a decade.

Adoption status doesn’t change the emotional impact of giving two girls £1000 and the third £50. The message is the same either way.

Posters on here are really stretching this.

That’s a really uncharitable leap, though. We don’t know he treated her unequally, and we don’t know he didn’t. But the fact he expected the same gift for her strongly suggests he does treat her as equal within his own household.

Most parents in blended families work very hard to make sure the children feel the same, it’s not unreasonable to assume that’s the case unless there’s evidence otherwise.

Saying “it’s far more likely he didn’t” is just projecting the worst‑case scenario because CFs exist. Sure, they do, but that doesn’t mean every man with a stepchild is automatically one. It’s a bit of a reach.

And even if he was imperfect (as most parents are), it still doesn’t change the impact of the aunt’s choice. The disparity in gifts sends a very clear message to a 17‑year‑old, regardless of what goes on inside her own home.

So yes, he can’t demand equal treatment from extended family, but he’s allowed to feel hurt when his daughter is singled out. That doesn’t make him a CF. It makes him a parent trying to protect his child’s feelings.

What you gave step niece was thoughtful and generous. Your db and sil are being grabby as fuck. SDN’s bio dad ought to pay half the lessons and her mum ought to pay the other half. Who has their step-aunt pay for lessons. Really unreasonable of them.

I’d say nothing. And think a lot less of brother.

Seriously, if you had step kids in your family for 8 years, you wouldn't want your family to accept you as one big family?

Has your brother adopted this girl? If not then he has a bit of a cheek expecting you to treat her the same as his own daughters when he hasnt done.

I'd personally think it's far more likely that he didn't.

And expecting it from his sister if he doesn't treat them equally himself could easily happen if he was a CF, and there's plenty of those out there.
