Hey man, congrats. It is amazing, isn't it? My daughter, also Abigail, just turned 10 months. I can't believe how much she has grown since she was that tiny, helpless creature. Of course you are nervous. You are now in charge of raising and caring for a human. An entire life depends on you and what you do. What an awesome responsibility, and such an honor to be the most important man in her life. Take pride and joy in everything she does and everything she is. Remember when it's hard (which it will be sometimes, those first 10 weeks were uh...challenging) that EVERYTHING about her will change in a few weeks. That also goes for every time you AH-HAH! figure it out...as in...this is how to get her to eat, sleep, stop crying, etc....it will work for 48 hours at best...then you get the "pleasure" of figuring it out again. Evertyhing, the joyous and the challenging...is "for now."
Now if you'll excuse me, I have to go help my wife clean the avocado and ouatmeal off the wall next to where Abby was "eating."
