congratulations, 2 years from now you will be wondering what you used to do with all the free time you used to have....... BUT you wouldn't trade him for anything.
More work than you ever imagined, and more fun than you ever thought possible.
I believe that being a good parent is the single greatest thing that any human being can ever do.
Creating a human being is a marvelous and wondrous thing to accomplish but parenting one to become a good and productive human being surpasses everything else you will do in life.
