What's a must read book for new parents?

I flipped through the pages of "No Regrets Parenting: Turning Long Days and Short Years into Cherished Moments with Your Kids" by Harley Robart on a whim one day because it was lying around on a friend's coffee table. Later, I borrowed it from her because I felt weirdly attached to it. It is a wonderful book with nuggets of wisdom for busy parents about being present in the life of your children. The book's size in its own right is a statement to busy parents -- they have no excuse not to read it no matter how busy they say they are.
