to tell my sister NOT to continue the name theme her DH started with her DSC?

[ZeldaMae]

DSis is married to BIL, nice enough guy and loves her to bits.

He has 3 DC - two mums (this is relevant).

His DC's names have a 'theme'. Think like the Kardashians, names spelt slightly unconventionally to go with a first initial which is also BIL's name and first initial.

So let's say he is Karl Kooper and his kids are Kolin, Khloe and Kathy. All have his surname.

Both his XPs happily accommodated his preferences and all DCs have his surname too.

DSis now expecting their first DC. She likes Olive for a girl and Ben for a boy. She did take BIL's surname.

BIL says baby won't 'go' or feel like part of the family (DSCs around a lot). He wants another K name. His suggestions are 'real' names like Kylie and Kevin.

DSis is wavering. I think she needs to take a stand! This is their DC not just his! Feels like an ego trip to me.

On the other hand, the DC will be part of a larger family. Maybe they would like to 'match'?

AIBU?

you're all right I can't and shouldn't and won't 'tell' DSis anything.

Her DCs her choice what to name them. I just want it to be her/their choice not all about BIL's little army of clones.

I will support her whatever she chooses.

Just say no

But if she doesn't maybe she could go with some kind of compromise. So having a non-K name that can be nicknamed with a K, e.g. MacKenzie can go by Kenzie for Dad. Or the other way round and Katerina can be known as Trina.

I know someone whose kids are all named after a particular premiership football team's players.

All pathetically sad well and good, but one of he names is forrin so the parents just pronounce it wrong, anglicising it.

And no thought for when the overpaid prime donnas move clubs.
The father started this nonsense with marriage number 1, words fail at the stupidity of the wife number 2.

Your dsis is the 3rd to perpetuate this frankly egotistical and idiotic trend.

I'd say no, and allow him the K name as a middle name. No way I'd lump my kids in with half a dozen other women's kids for the sake of a now thrice married bloke

They should both get a say but it should be a name they both like and agree on.

Siblings with the same letter sound daft so I can see why she wants to break the trend.

However, given his past form of having children and moving onto the next new family I'd say the childs name is the least of her problems to come.

I personally think it's absolutely fine if they don't 'match', they're people not teacups. But it doesn't even make sense, imo, to 'match' all the children's names as they are all a part of an extended, blended family. For this type of theme it seems that the man is the important part, the nucleus; the children are am extension of him and the mothers are largely irrelevant. Even if the mothers' names' did fit a theme it's purely coincidental. He's not choosing women based on their names/initials (right?!)

It makes more sense to me to begin a new pattern with a new family (or new branch of a family) if you're going to go down this route at all.

Themed names are wanky, I know three sisters whose names begin with, say, Z. The third one is completely made up, it's just daft.
