Vote! Which name do you like more?

We need a girl name for our new baby. We got stuck in a C name theme. Which name do you like better to go with big sister Carmen? We like both, but have minor concerns with each. We’re certain it’s one of these two so no need to offer other name suggestions.

Caroline (A little concerned its spelling is too close to Carmen. Does the pronunciation seem different enough?)

Charlotte (Number 1 or 2 name in our state. Should we be concerned that there will be a ton of other Charlotte’s or Charlie’s? Do kids care if others have the same name as them these days?)

Thanks!
