DH and I were sold on Florence but agreed to keep it to ourselves till DD was born.
Then SIL has a surprise girl and DH has a meltdown over whether SIL would choose the name Florence so we agreed to tell her early, turns out it was on her shortlist and she agreed not to use it.
Since then I found out it's a more popular name In the UK than I thought (#19 for 2018, stupid USA baby centre had it at 900+) and I've fallen out of love with it a bit. It was important to me to choose a name that was recognizable but unusual enough to be special so I'm sad it doesn't have that quality after all, it's still a lovely name.
DH is livid I'd think of changing it after we 'stole' it from SIL but I don't want to be beholden to a name when DD isn't even here yet.
How popular is it really? Are there lots of Florence's in playgroups and classrooms?
