One of my friends, Ted Rubin, likes to say that fatherhood is about "moments, not milestones."
We put a huge emphasis on graduations and birthdays and the like, but the real moments, when you earn your fatherhood merit badges are in the unexpected moments.
Last night, for example, males in the Epstein household were both simultaneously afflicted with a pretty nasty stomach virus.
Now, no one enjoys throwing up and no one enjoys cleaning it up, but at 3:30am when your son is hurting and you're the one he needs for support...and you're there to give it to him, that makes you feel great.
Yes, I know...it's crazy, but even at that point, you don't mind cleaning up vomit, because these are the times where your child knows you are there for him/her, when you know you are there to be supportive, and where you have absolute clarity about what's really important in life.
He'll remember the fact that you kept him company at 4am.
