I think Faith is perfect!!!! I agree that it may not be your MOST favorite, but it sounds soooo beautiful with Gavin, Finn, and Grace!!!! If this was your first baby, then you would choose a different name, but it is a perfect fit.
I LOVE that you are using your name as the middle name!!! If we have a boy this time, his name will probably be Christian...since I am Christina. My DH is Daniel so Emmie's name is Emilia Danielle.
It's funny that we are both expecting baby #4!!! Now.....please help me find a baby girl name to go with Collin, Elizabeth, and Emilia!!! Awwwww!!! :)
