Congrats!
Sleep now, it won't come again for several months after
Be a part of your kid's life. Coach, go to school meetings, know what happens at school. Work is NOT more important than your kid.
If you have a boy, kiss him good night EVERY NIGHT. My father is a serious homophobe and won't even give my son a hug. But I kiss him, at least on the forehead, every night when we say our prayers before bed.
Oh, and work is NOT more important than you kid.
Do NOT get jealous of the attention your wife lavishes on your child. She still loves you, even when she blames you in the delivery room for getting her pregnant
Did I mention work is NOT more important than your kid?
