AITA for not changing my baby’s name AGAIN after I changed it for my sister once already?

A mother’s heart is woven deeply with love and memory, carrying the names of grandmothers past as a legacy for the future. In the quiet anticipation of a new life, she chooses names that bind her children to the cherished women who shaped their family’s story, hoping to honor them both without causing rifts in the fragile bonds of sisterhood.

Yet, the tender act of naming becomes a battlefield where love and grief collide, as her sister stakes a claim on the name that holds their shared history. In the struggle to keep peace, she finds a delicate compromise—Rosalie—a name that carries the spirit of their nana Rose, a symbol of the unspoken sacrifices made to preserve family harmony amid the quiet ache of divided love.

AITA for not changing my baby's name AGAIN after I changed it for my sister once already?

I have a 9 year old daughter, and another on the way. I had 2 grandmothers: “Annie” and “Rose”. I named my oldest “Annabelle”, after nanny Annie, whose full name was also Annabelle.

I did not name her after nana Rose as at the time she was born, nana Rose was still with us. When I found out I was pregnant with a second, I decided to name her after nana Rose, who passed in 2017.

My sister, “Lucy”, got pregnant about 5 months before me. She says that she wants to name *her* baby Rose, after nana Rose. I say our kids can share the name. She says I already have Annabelle, and I could have named her Annabelle Rose or something but passed up the chance, so I can’t also have Rose.

I figure this is not the hill to die on, so I say I’ll look for something else, but reserve the right to use Rose. I then crack open a baby book, and a few entries after “Rose” is “Rosalie”.

It’s perfect. Honours nana Rose, doesn’t piss off Lucy, and my boyfriend loves it. Lucy finds out the new name and says it’s lovely and she approves, which annoys me but I say nothing.

This all takes place in the 8th month of her pregnancy, 3rd month of mine, so I don’t even know the gender yet and this is all hypothetical.

A couple weeks later Lucy gives birth. A few days ago, about a month after birth, she announces that her daughter’s name is Rosalie. At this point, I’m really annoyed, because I went to great lengths to leave the name Rose available, and she’s nicked my choice.

Mum calls me to say she knew what Lucy was planning and she hopes I’m not upset, because this means I can now name my incoming daughter Rose. Except I’m now attached to Rosalie. I tell mum that I’m sticking with Rosalie.

She says Lucy has Rosalie, I say there’s going to be 2 Rosalies in the family. She says this is impractical as both Rosalies will have the same surname (sister is a single mum, boyfriend is taking my name) and they will likely be in the same school and year group, so this will cause all manner of issues.

I say if it’s going to be an issue, then I’ll deal with it if/when it comes up.

Lucy then calls me, calling me an inconsiderate prick, and says I’m being petty, that I don’t have a monopoly on the name, and that she can name her kid what she likes. I said that’s all true, so by that same logic I can use Rosalie.

She says there can’t be 2 Rosalies, as it’ll cause problems, and I say she’s the one who has a problem with it, so she can change her kid’s name or deal with it. She again called me an inconsiderate, spiteful, arse, and hung up.

Mum, dad, and our brother all side with Lucy.

Edit – I appreciate the alternate name suggestions that stem from Ros(e)(alie), and I do find reading them interesting, but I did say that all names are fake, so, in the nicest way possible, Ros(e)(alie) inspired names aren’t really helping me lol.

Also it has been confirmed I’m having a girl.

Here’s how people reacted:

NTA yet for being frustrated with your sister. She’s put you in a weird situation for no reason other than to be difficult (and other people in your family let her so that’s also very frustrating and bizarre).

That said, I do think you WBTA if you name your daughter the same name just because you love it or it might spite your sister. If, as you say, there’s a likely chance that they will be doing things together, it will probably be irritating for them to have to deal with all the time. Kids are brutal and also sensitive- why set your kids up to dislike or resent each other just because you like a name? Also, there’s a good chance that if you both choose the name, it *will* come up with your kids and you’re going to have to be very careful to not let your kids in on any of the fighting that will almost definitely continue to happen throughout their lives. Their names will literally be synonymous with conflict and that isn’t good for anyone, let alone kids.

In fairness, I am likely biased because I was named after someone in the family and I ended up changing my name and it became a *huge* deal to everyone else who apparently had a stronger connection to the name than I did. I wish my parents specifically hadn’t gotten so attached to a name that they made me suffer through having it even though it made me uncomfortable. Don’t do that to your kids. Kids are people who are going to grow up and live with certain decisions that they didn’t necessarily make. Decisions made for kids should be done in service to the kid- not the parent. You may love the name- you’ve built a relationship and it means something to you. Your kid isn’t going to have that relationship with it- they may appreciate the memory of nana Rose- but they aren’t going to have known her like you have so the bulk of their relationship to their name will come from their experience of it, which sounds like it will be an issue.

ESH because this could cause issues for your daughter. Think of her in this. For example, what if cousin Rosalie posts something inappropriate on social media while your Rosalie is looking for a job? Of course, this happens to unrelated people but these 2 may look alike and will be from the same area. And your Rosalie (along with her cousin) will have to deal with the irritating consequences of having the exact same name at the same school. I don’t think you’re thinking about your daughter here, only how mad you are at your asshole sister. I’ve watched my father and a friend of mine deal with having the exact same name as their cousin and it ranges from an annoyance to an actual problem (the job example happened to my friend). Don’t make your daughter the “other” Rosalie to your sister’s “original” Rosalie. It’s not fair to her.

I suspect I will be downvoted here.

ESH, mostly Lucy, but please take some deep breaths. Where do you want to be 10 years from now? Do you want to have a warm relationship with your sister? Do you want two cousins with the exact same name having constant issues at school? You may have to give a little here. Sometimes family dynamics are stupid and unfair and pregnancy hormones are no joke and elevate issues that could normally be talked through like rational people. You have every right to name this child Rosalie, but is it in the best interest of the child and your family, or are you doing it because you’re pissed off and want to make a point? Is this really about your grandmother at this point? Families are complicated, and sometimes you lose the battle but can win the war.

ESH. Sister is petty and sucks for stealing Rosalie. But you are making it just as big of a deal. What actual “great lengths” did you go to to keep the name Rose available? Looking into another name? That’s a bit of an exaggeration. It shouldn’t be a contest over honoring grandma. The fighting and petty childish name competition is reflective of selfish motivations rather than the honoring of someone deceased. Do whats best for your child. Shouldn’t that matter more?

NTA. They’re going to give your daughter a nickname you hate though. Your sister and mother are jerks for cooking up/knowing the plan to “steal” your name which is exactly what your sister was accusing you of doing.

I have a friend who shares a first and last name with a cousin. It’s really not that bad. They work in a family business together too and they just get used to bouncing things between each other if/when there is confusion and they need to.

Noclevername12

ESH, I think. That said, if they weren’t going to the same school, I would be like just go ahead and do what you want. But I think having two kids with the same exact name in the same school and grade sounds like an absolute nightmare and I would not do that to myself as the parent, let alone them. Wait till their standardized test scores get mixed up.
captainsadlyplank

NTA but your sister is.

I’ve worked with cousins in the same company who had the same first, middle and surnames, and they weren’t the only ones in the family with that name. It was funny but no big deal.

Like someone says, give her an awesome middle name and she can choose what she goes by as she gets older.

SpaTowner

ESH, potentially, except your Dad.

Your sister has been an out and out arse, but it sounds like she is in a rougher place than you and, well she’s done it now hasn’t she?

Treat it as a fait accompli, find another name and let it pass.

MelonKanon

You know what? NTA.

I usually think name arguments are stupid. You keep that name and give the kid a kick ass middle name. She knew what she was doing, out of spite.

You literally went out of your way so she get the hell over it.

Shaziiiii

ESH. You “reserved” the name Rose when you were 3 months pregnant? Even though your sister said she wanted to name her rose before you said it? You are all acting childish and immature.
badasscertified4

NTA. She literally wanted Rose then changed her mind when you found Rosalie. The irony in her calling you petty is truly immeasurable.
emeraldechos

Esh

Everyone needs to have some maturity and stop acting like children. Name your kids whatever you like you and your sister both.

Ipluckingtry

ESH except your dad. Everyone is being petty AF. You, your sister, and your mom need to remember your adults and act like it.
jfeld22

ESH. Rosalie is such an outdated name… Both of your children will have issues later in life due to their names.
4thxtofollowtherules

NTA but honestly your first mistake was giving in and negotiating with your emotional terrorist sister.

Conclusion

The original poster (OP) experienced significant emotional investment in securing the name ‘Rosalie’ as a tribute to their late grandmother, a choice they made after initially yielding the name ‘Rose’ to their sister, Lucy. The central conflict arises because Lucy preemptively adopted the newly chosen name ‘Rosalie’ for her baby, which the OP views as a breach of an unspoken agreement and a direct challenge to their right to honor their grandmother.

Given that the family overwhelmingly supports Lucy’s position that having two children named Rosalie with the same surname is impractical, should the OP feel entitled to proceed with the name Rosalie, or should they concede the name to avoid ongoing family friction and perceived logistical difficulties?
