How about Milagro? It's Spanish for miracle, which seems appropriate since you're apparently a guy...

Seriously, congrats. You and your love are the only ones who can name your child, but do try to remember that your future son is the only one who has to live with your choice. Considering that you're one day going to teach him how to sneak up on wary critters and kill them for recreation I'd be careful with that choice if I were you.
