You can count me as at least one new dad you've, well, not necessarily met, whose primary concern is more along the lines of, "How the hell am I gonna be involved with my son's life?" (:
I’m actually in the process of changing careers due to the realization that remaining on my current track would put me at work before they get out of bed and home from work after they’re in bed for the next 15-ish years. I refuse to miss my kids growing up during this one shot at life I have.
It's really amazing to me how this child has changed us and our lives. Not to say that my wife and I expected the kid to pop out and life to return to business as usual, just that I didn't truly comprehend how profoundly this experience would change me. It's intense.
This is so huge, not only so your kids know their extended family, but also to have some basic help. We've found that even my sister who lives 45 minutes away is just a bit too far to see them as frequently as we'd like, with her busy family and all. My advice is to move closer than you think you ought to!
I’ve been able to arrange things and arrive at work a bit later, so I see my kids each morning and take them to school. Then I stay a bit later at work. It also means I don’t see them most weeknights, but I see them every morning (barring the rare unmovable meeting).
Some of my colleagues do opposite. But there are also parents that just don’t see their kids at all until the weekend.
