Um, I don't mean to rain on your parade but my youngest daughter's name was supposed to be Nicholas Ryan so I am of the belief that until the baby is actually on the OUTSIDE you should be prepared for either one.....Although you could always call her Danni :)
I'm going to guess around 10:00 PM tonight (because they will be late inducing you, as hospitals are ALWAYS behind schedule) and the baby will be about 8 lbs which is HUGE for a joey!
And I can't believe you're not naming him Joey!
Oh or Rudy (the Christmas Joey!)
Edited to add: I guessed these without your previous history since it took me forever to type it while changing diapers and cutting out foam Santa Claus' and Christmas Trees for our Christmas cards that we are making this afternoon!
