Congratulations.
Having a child changes your whole perspective on things. There is nothing I've found so transforming in my life. It really helps you understand your meaning, purpose, and everything about life. Every day is a new adventure.
Cherish the first few years. They go by so fast. I can't believe my little guy is starting 3rd grade on Monday. Before you know it they're off to college.
PS - the first 6 months are a lot of work with the diapers, feeding at all hours, crying, etc. You have to have lots and lots of patience. Its very stressful on your marriage. The women get that post partem thing sometimes too, which you have to work with. It gets a lot easier after the 2nd year.
