I quite like Kai too, but come from where I come from it means food, so that's a no-no...as is Mimi, which I also love, but means wee!
Friend used to teach a little boy called "Baki" which was short for "Back of the Regent Theatre" (where he was apparently conceived) Horrifying! I can't believe it was allowed!
My friend in Australia has called her 4 boys Lachlan, Lincoln, Lleyton and Landon.
Friend called her little boy Hubert, which I initially chortled at (to myself!) but have got used to now.
