I absolutely love the name [name_f]Bea[/name_f] for a little girls nick name. The only names I can think of that go with [name_f]Bea[/name_f] are [name_f]Beatrice[/name_f] & [name_f]Beatrix[/name_f] which I’m not too fond of. Any ideas for a first name and a middle name for [name_f]Bea[/name_f]?
[name_f]Maeby[/name_f], [name_f]Phoebe[/name_f], [name_u]Ruby[/name_u] or [name_u]Toby[/name_u] spring to mind
But I think [name_f]Bea[/name_f] could work as a stand alone name
I’d pair it with something longer/more traditional to balencd it out
Maybe
[name_f]Bea[/name_f] [name_f]Elizabeth[/name_f]
[name_f]Bea[/name_f] [name_f]Katherine[/name_f]
[name_f]Bea[/name_f] [name_f]Isabelle[/name_f]
[name_f]Bea[/name_f] [name_f]Juliette[/name_f]
[name_f]Bea[/name_f] [name_f]Rosalind[/name_f]
[name_m]How[/name_m] about [name_f]Elizabeth[/name_f]? I am thinking of using that as a first name with the nickname as [name_f]Bee[/name_f]
I agree that [name_f]Elizabeth[/name_f] nn [name_f]Bea[/name_f] would be adorable! Anything with a prominent “B” sound, or even something that starts with a “B” or contains the “bee” sound ([name_u]Ruby[/name_u], [name_f]Phoebe[/name_f], [name_u]Ashby[/name_u], [name_f]Bianca[/name_f], [name_f]Bethany[/name_f], [name_f]Belle[/name_f], [name_f]Bridget[/name_f]/[name_f]Brigid[/name_f], [name_f]Bellatrix[/name_f], etc., etc.), if you want to be more picky. I’m not usually one to go the nicknamey route, but I rather like just [name_f]Bea[/name_f], too, and I liked some of @gr19’s suggestions. [name_f]Bea[/name_f] [name_f]Isabelle[/name_f], [name_f]Bea[/name_f] [name_f]Rosalind[/name_f], [name_f]Bea[/name_f] [name_f]Elizabeth[/name_f]. I would add [name_f]Bea[/name_f] [name_f]Rosalie[/name_f], [name_f]Bea[/name_f] [name_f]Penelope[/name_f], [name_f]Bea[/name_f] [name_f]Evangeline[/name_f], [name_f]Bea[/name_f] [name_f]Theodora[/name_f], and [name_f]Bea[/name_f] [name_f]Clementine[/name_f]. 
There’s also the related (to [name_f]Beatrice[/name_f], I mean) [name_f]Behati[/name_f] or Beatriu (bee-ah-troo). I love [name_f]Beatrix[/name_f], but not [name_f]Beatrice[/name_f] so much, so I can understand not being too fond of either. I think Beatriu has an adorable sound and a funky, international look, though! I think it’s the Catalan form of [name_f]Beatrice[/name_f].
Good luck!
[name_f]Elizabeth[/name_f] would be cute as well as [name_f]Bethany[/name_f], [name_f]Beverly[/name_f], [name_f]Thisbe[/name_f], [name_f]Isabelle[/name_f], [name_f]Tabitha[/name_f].
