I'm going to be totally honest with you. This is not a "how-to," a "when-to," or a "what-to-expect" book. It's not even endorsed by anyone remotely connected to the medical profession. "But if I have only one book to buy," you ask, "shouldn't I go for the helpful one?"
Let's compare:
Those know-it-all books tell you how to care for a newborn child.
My book describes how tired I am.
Those books give you essential information you can use in a life-threatening emergency.
My book has some very amusing anecdotes about poop.
So really, it's up to you.
