Which of these two names for a girl?

Husband and I are trying for number one, but we wanna decide on a name now so when we find out the sex, we can get personalized baby items right away. It's between two girl names right now…
First a little background info on the mommy and daddy:
Mommy is 23 an Daddy is 25, both Caucasian. Daddy has Irish and Italian in him, Mommy has Irish and supposed to be Cherokee but I don't see it. Both are fair skinned, but daddy tans better, mommy freckles. Daddy has hazel eyes and mommy has dark brown. Both have natural light brown/blond hair.

The names we're between are
Kairi Anne Smith (nick named Kai)
Yuna Lynn Smith

Kairi is not pronounce Care-ree. It's pronounced Ky-ree.
