I do rather like Michellie it has a sweet sound to it but I don't really like the spelling Mikaley because it looks like it's supposed to be
Mikayla or Mikenzie, just rather uneducated looking somehow. :(
Michellie is a better spelling but could be mistaken for Michelle-ee you know. So something like Michalie or Michaelie would be better although all of these spelling look so made-up! It' too bad bacauce the name is rather cute! :)
