17 years ago my (ex) wife and I bought a small handful of books. Despite my enthusiasm for the books, I don't think I read any of them past the preface, especially after our son was born; buy what appeals to you, and don't overthink things.
Our son graduates high school in another year. He's a viable human being, he likes people, people like him, we love each other. I have no idea how that happened.
No one knows how to raise a child, but we mostly seem to do OK.
Do what your wife's doctor says for health and nutrition. Do what your eventual pediatrician says for health and nutrition. Buy black and red mobiles.
Hold your child a lot. Play with your child a lot. Talk to your child. Read to him. Sing to him. Give him toys and books. Show him everything, but not all at once. Tell your child "I love you" for the rest of your life, and show him.
Enjoy the ride.
