I have two daughters - [name]Haven[/name] and [name]Fiona[/name]. I’d love to name my third [name]Sophie[/name], but it’s [name]Fiona[/name]'s middle name.
I’m torn since I don’t really like many other names…love [name]Sophie[/name]!! 
But being the middle child and losing both your middle name and your spot as the baby to the younger/cuter new baby of the family I think might be too much.
Help?
I don’t think you should use [name]Sophie[/name] if it is your other daughter’s mn. [name]How[/name] about [name]Sadie[/name] or [name]Sylvie[/name]?
I would probably keep looking; if you really don’t find another option you love, then I think it could be considered, but I would try to leave [name]Fiona[/name] her middle name and find a great new option. I don’t know if you are looking for suggestions that go with [name]Haven[/name] and [name]Fiona[/name]… If you aren’t, ignore the following list, haha?
I think that [name]Haven[/name] and [name]Fiona[/name] are both spunky and sweet, not too long, but generally feminine ([name]Haven[/name] is more unisex, but has sounds like [name]Ava[/name]…). [name]Both[/name] are more modern in their usage. These might fit well with your set:
[name]Lucy[/name] (or [name]Lucille[/name] or [name]Lucia[/name])
[name]Ruby[/name]
[name]Audrey[/name] or [name]Aubrey[/name]
[name]Claire[/name]
[name]Molly[/name]
[name]Tessa[/name] or [name]Tess[/name]
[name]Ellery[/name] or [name]Ellison[/name]
[name]Rose[/name] or [name]Rosalie[/name]
[name]Annabel[/name] or [name]Mirabel[/name]
[name]Connelly[/name] ([name]Nell[/name]) or [name]Connolly[/name] ([name]Nola[/name])
[name]Elodie[/name]
[name]Alice[/name]
[name]Gemma[/name]
[name]Cambria[/name] or [name]Cambrie[/name]
[name]Isla[/name]
[name]Sukey[/name]
[name]Sylvie[/name]
[name]Celie[/name] ([name]Celia[/name]) or [name]Seeley[/name]
[name]Sadie[/name]
[name]Josie[/name]
[name]Zoe[/name]
[name]Reese[/name] (perhaps from [name]Theresa[/name])
Oh I don’t think you could use [name]Sophie[/name]…I have never heard of anyone naming a child w/ another’s middle name. It is a sweet name though so I can understand why you’d want to have it as a first name for one! I like the [name]Sadie[/name] suggestion.
