Congratulations on the good news.

I listened to many fathers, asked their opinion on how to be a great Dad, when my Daughter was born 33 years ago.

Several pieces of advice that seemed to be good to me then and now:

1.  It takes a lot of time to build them up, but only a word or two to tear them down.

2.  Teach them to say no.

3.  After 21, if they haven't learned what they need to know from you, just stand back and wait for them to ask if they need help. 

BIL told me #1, he had 4 girls and a son, they are all great people, and it seemed to be true for me.

Good friend and lay preacher, guy I taught with, told me #2.  As the years go by, I see so many people that have never learned to say no, and it tells in their behavior and they way they live their life.  My Niece is currently taking education classes after raising all her girls (3) told me they are teaching teachers to not say no to kids under four years old.  Sure seems a mistake to me.  Charlie (Luther) Miller was that friend and raised two great sons and a daughter that all live great lives.

Another BIL told me #3, he raised 3 great boys, they all come to him for advice now.

Listen to those successful Fathers around you, they have great advice and experience for you, some you ignore, some you take to heart, as all will not be excellent.

Use common sense, which is not that common.
