Re: New Fathers?
Having three now (7, 5 and 2), I am reminded of how comparitively easy having just one was (I didn't think so at the time, of course). You'll be just fine.
As for advice from others, we mostly ignored it. But just in case, here's my suggestion:
Don't be THAT PARENT who does nothing but talk about your kids with others. Most people don't care (just like you don't care what color their kid's poop is).
