Cosmo as a baby name?

Having a baby boy. Is Cosmo cool or too much? Our surname begins with a ā€œCā€ too.

It immediately makes me think of the character from Fairly Odd Parents so it would be a no from me because of that.

I don’t think it sounds remotely posh though and I do really like Cosimo as PPs have suggested, although I can’t imagine it flowing well with any typically british surnames so that might be something to consider if that’s the case for you

It has a really cool sound - and would make a fab middle name or even a nickname for a boy who adored everything to do with Space (and seemingly a lot of young boys go through a Space phase, if it’s not Dino’s or Vehicles).

But I think as a first name it’s a bit limiting for him unless you somehow know he’s going to be arty, preferably always live in a big multicultural city, have a more UC social set etc. I personally tend to sway towards names which sound like they could fit in on both a building site and a judge’s chambers for an easier life and I’m not sure Cosmo fits that brief.

You’re right — her daughter is Cosima, (and apparently used to be known as Mimi. A friend of mine taught her years back.) Much nicer than Cosmo.

I actually quite like it.

My daughter has a friend called Cosmo and he's lovely, as are his family. They are both at state school and there has been no bullying about it.

Screams of desperation and new money.

I love Singin’ In The Rain so Cosmo has nothing but happy associations for me. ā€œMoses Supposesā€¦ā€ etc

Can you afford to send little Cosmo to a private school?

Because round our way you'd get seriously bullied for being a posh git with a name like that in any of the state schools.

That's really sad. My kid(s) have slighty unusual names amd go(went) to a rough ass state school. They have never been bullied about their names and they are certainly not the only ones with unusual or heaven forbid - forgien names 🤯

Cosmo was on my list OP, I love it.
