Congrats, very cool new things you are about to experience.
No need to worry about a name however, cause usually the female side of the child bearing thing is usually who names the child (and they are hard to budge when they pick one). Just set back and throw in your name ideas here and there.
Have fun, they soon become your best freinds.
BTW females are EXTREMELY emotional during the last few months, so prepare for that.
I once was lost, but now........... I'm still lost!
