I don't have a specific book but instead I have the advice I was given three years ago before our first kid was born: "Pick a book both of you connect with and ignore the others". Up until that time my wife and I would look at any book with the word "baby" in it, read a few pages and assume it was THE book. The problem was that we typically never agreed on one which led to conflict which is something you don't want, you have enough stress already.

Looking back though we didn't really gain anything from books, it really was all on the job training. It's scary as shit and you'll reach limits of stress you never knew existed but even with all of that it is still awesome.

With a newborn the routine is pretty basic: eat, poop, sleep. If you are having issues ask your pediatrician. If your child is unhappy think about why that might be. Things are very simple in their world so don't over complicate things and think as if they were an adult (we were guilty of that).

Good luck and enjoy the snuggles while you can!
