Buckle up, your life is about to change and it will be an adventure. You essentially get a "mini me", and your wife will get someone who will crawl right into her heart and stay there. There are a TON of books on raising boys but rest assured yours will find a way to be uniquely your special brand of crazy. Enjoy every minute of it, even those screaming/crying fits at 2:00am. Yes, he will do the random disgusting things that only baby boys can do (projectile poo comes to mind, and the magical snot rocket sneezes). He will also melt your heart when he calls your name with excitement and launches himself into your arms. God Bless you and your wife on this adventure, stay close to each other through the exhaustion. The best gift you can give that little guy is parents who love each other, love him, and look out for him.
