I ended up naming my daughter [name]Cara[/name] [name]Beatrice[/name] [name]Vita[/name]. Now Im trying to think of a nice nickname. Something more unique than [name]Cara[/name] or [name]Bea[/name] (and if ever which of these do you think sounds better?) Any comments or suggestions would be welcome. Thanks!
Its a beautiful name and [name]Cara[/name] is fine! I like [name]Bea[/name] too.
Well I really love [name]Cara[/name] and [name]Bea[/name] but you could also think about…
[name]Bea[/name] prn [name]Bay[/name]-a (like Italian) instead of [name]Bee[/name]
Vee from [name]Vita[/name] / similarity to [name]Bea[/name]
[name]Trixie[/name]
[name]Beata[/name] (Italian [name]Bay[/name]-ah-ta), kind of get it from [name]Beatrice[/name] + [name]Vita[/name]
[name]Vit[/name]
[name]Carrie[/name]
[name]Cara[/name] or [name]Bea[/name] are good. If I was the older sister, I’d be tempted to use Care [name]Bear[/name] (in a nice way!).
I like both [name]Cara[/name] and [name]Bea[/name]. I actually like the idea of [name]Cara[/name] [name]Bea[/name] as a double-barrel nn, too. Or have you considered [name]Kit[/name]? I think the “C” in [name]Cara[/name] and the “it” in [name]Vita[/name] could combine for [name]Kit[/name] (or even [name]Kitty[/name]), for a more unusual, cute nn.
Good luck!
ETA: There are also quite a few cool nns for Beatrice that aren’t just Bea–Trixie, Tess, etc. I think Tess is adorable, actually. 
The protagonist in the book Divergent is named is [name]Beatrice[/name] nn Triss. I came to quite like it while reading the book! I also really love [name]Bea[/name] and I love the sweet [name]Cara[/name] as well. Beautiful name!
