While I'm busy improperly supervising someone else's kid, let's name my brother's baby!
My favorites are Wyatt Alan or Griffin Garrett. I also like Parker Vance and Ace Alexander.
Here are some others I've been kicking around:
Ethan
Everett
Alexander
Caleb
I know he liked Gavin and she likes Mason, and both of those are fine. Ashley has been suggested several times, being the uni-sex wonder that it is, but no dice. I also love, love, love Truett with the nickname Tru, but with his last name it becomes a kick-ass, movie title-like phrase, which isn't what they're going for.
Now give me your suggestions, he needs them and naming babies is fun!
