Welcome to the blessed hope in our future through the children in new found life. As a father of 5, I suggest you reflect upon life now, and then reflect back some years from now. Most fathers are rather surprised by how much they themselves change in worldview.
Kids are a blessing, especially after they're grown and gone. I have 3 sons and two of them work for me in my business so I don't have to. The one thing I regret is we didn't take a whole lot of pictures (too expensive to develop back then)so the memories are starting to fade. Get lots of pics.
And if it's a boy, get the 4x4 project truck (preferably a K5 Blazer) going right around age ten so it can be finished by the time he graduates.
