Wow! I [name]LOVE[/name] [name]Dahlia[/name], and [name]Louisa[/name], [name]Eloise[/name], [name]Beatrix[/name], and [name]Eliza[/name] are among my favorite names.
You said you have three children. Is [name]Lily[/name] your only other daughter? If you have three daughters, with only two having floral names, the third daughter’s name will feel like it doesn’t belong, but if this baby will be your second daughter, and you aren’t averse to a floral theme, why not? I think it’s truly a matter of personal preference.
On the bright side, not everyone will associate [name]Dahlia[/name] with the flower (I was so surprised by this when I recently asked people about the name), so that’s something to keep in mind if you’re still uncertain. (There’s another name, [name]Dalia[/name], that isn’t a floral name.)
I honestly think it comes down to what you think and how you feel. If I met you, and you introduced your little [name]Lily[/name] and Dahila to me, I’d notice their lovely names first, and then think it sweet that they’re your little flowers.
I [name]LOVE[/name] [name]Dahlia[/name] [name]Beatrix[/name] and [name]Dahlia[/name] [name]Mae[/name], and [name]Eliza[/name] [name]Beatrix[/name] is the name I plan to use someday (hopefully sooner rather than later!).
P.S. I think [name]Lana[/name] is destined to encounter pronunciation issues ([name]Lon[/name]-nuh, Lan-uh, [name]Lane[/name]-uh, etc.)…
