Quoting Momma Of Girls:" Im 25wks & still no name for baby girl. Our daughters are Kaylee & Kennedy & hubby wants ... [snip!] ... & cant agree on one we BOTH like. Very frustrating any help is greatly appreciated because we are completely stumped!"
How about Kimberly?
Maybe Kezia (I believed it's pronounced 'Asia' but with a K in front, I personally like it) Korissa, Katrina, Katerina, Kaia (like 'Maia' but replace the 'M' with a 'K'), Karoline, Keelin, or maybe Kelley (Unless this may sound too similar to 'Kaylee' - you have another daughter who already has this name, right?).
Or what about Kelsey? I know it's not particularly unique, but it hasn't really been that common a name nowadays, people seem to be going towards more original, unique names. So Kelsey wouldn't be the type of name you'd find three girls in the same class with, along with it being able to be spelled in a different number of ways to add to the originality.
Also, I think the names Kennedy, Kaylee, and Kelsey flow well together. =)
But that's just my input.^^
There's also Kiana, Khloe, and Kirby.
