What I found was that, right about when you thought you had a glimmer of hope of mastering the current stage of your child, they moved on to the next one. So I was always one step behind. I can tell you a lot about what worked for them in the past, but not much about what works on them right now :)
I will say its a miracle more teenagers aren't murdered in their sleep by their parents.
Find your own style and works best for you and your wife. There are many paths to get to the same destination. Listen to everyone, develop a good BS filter, evaluate it on your own judgment and value system, and go from there.
Establish a good relationship with an accountant, a lawyer, a doctor, and a bartender. You'll need them all.
I can tell you it's the best thing to ever happen to me. Some days are better than others, but they are all better than my life before.
And, I kick some serious tail at Lego Star Wars on the PS3 now, which is nice.
The only advice is to follow your gut. And help her out. All you can.
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).
Welcome to fatherhood. My daughter is 5 and my son is 3 and they are the cutest smartest kids in the world. They are also the best and worst kids in the world. You will feel the same way about yours. I only have two pieces of advice/wisdom: 1. Parenting is an active vocation, do not attempt it from the couch/bed/chair. 2. Revel in the journey, your child will amaze you with beauty, smiles, intelligence, everything. Enjoy it! It is awesome like nothing else.
If you have specific questions, concerns, joys to share RZ is an awesome place with real parents who would love to help/share your life experiences.
Here's a practical tip. Apricots make baby diapers into chemical weapons suitable to put down a small uprising. Avoid at all costs.
The one thing I'll add as a father of a 10-month old is to never forget that no matter how hard it is at times on you, it is always tougher for your wife. You might think you are tired, but I can guarantee she is more tired.
