Which spelling do you like best for a little girl, and need a middle name suggestion..?

I like the spelling Kaelyn, but I'm not sure if that's the pronunciation you're going for (Kaylin?).. of the spellings you've listed I like Kalin. I don't have any middle name suggestions..mostly because I'm a believer in the middle name having meaning, like after a family member or someone special to you..that's just me, though..otherwise, what's the point of having two names? Pretty name, though. :)
