Then I saw 1stTimeMumma88's thread a day or so later and she mentioned the name too (don't worry, I'm not name-stealing - I'm not even preg!) and I thought oooh it really is lovely!
It is such a lovely name, it is a modern name but its not overly common, i know only one Kailey and its spelt Kaelie (which personally i dont like). I'd only be ticked off if someone i am close with stole my name but even then id still use it.

Its funny the name came to me when i was using some silly baby name generator. I had my sights set for Summer but now its Kailey Summer and i am very happy with that.
