That is the coolest...
I am not trying to teach you how to raise your kid, but let me say this now.

I have a daughter that graduated HS last year and is attending college with honors and my son just graduated HS and will be starting college in the fall...
I am telling you this because there has not been one college graduate in either my wife's nor my family in several generations. Many members of the military, regrettably, myself excluded...

Read to her every night. Sounds over simplified and maybe even a little silly, but they will thank you for it later. Just sit down on the couch after bath time and have your quiet 20 minutes and read ANYTHING, I will make my personal favorite as a recommendation, the Dr. Suess "B" book...

Let them fail once in a while, it is healthy, you want them to succeed, in order to do that they need to know what failure feels like. I am a firm believer in the fact that you learn more from your failures than from your successes.
Help them to help themselves, this one was hard for me.
You have no idea how awesome the next 19 years are going to be.
You will get frustrated, don't think for a moment you wont. But this is your education.
Congratulations.
I had no clue what I was getting myself into... Thought I would pass on what hit me as s surprise.
