Charlie is such a cute name for a boy! Mia is a lovely name too!
For our girl name I have Renley picked out---Ren for short. I am dead set on this name and it works with our others boys names which can all be shortened to 3 letters. We have a Sam, Dex and Ted.
and thanks, I DO have just as good of chance as anyone else at having a girl! I have a lot of people rooting for me too which is nice. I know I will have a lot of baby showers if I hear pink!
