Would it be naff....

...to let DS call his new baby sister Elsa? He's obsessed with Frozen!
I love the name and had a lovely great Aunt named Elsa.

If you genuinely like the nane then not naff at all, rather sweet actually!

Elsa is a super name. I don't know anything about Frozen. I guess there are films being made all the time and the characters have to be called something so at some point someone's going to name their kid the same thing as a character in a film.

I wouldn't overthink it, and I'd just be pleased he's not obsessed with Spider-Man or Godzilla!

Thank you very much Ditzy and Uri.
He did say that he didn't want her to have magic powers!!

We named ds while watching the tennis - turns out MIL's dad had the same name as a certain top-class player Nadal

One that basis, it's a lovely name and a lovely way for ds to be involved with his little sister!
