Perfect Parenting: The Dictionary of 1000 Parenting Tips, by Elizabeth Pantley.
This book is neat. When you have an issue with a child and just need some ideas as to how to handle it, just turn to one of hundreds of alphabetized topics, from "Allowances" to "Nightmares" to "Yelling and Screaming". What I liked about this book is that it is useful no matter what, if any, parenting philosophy you subscribe to, and does not claim to have only one answer for every child in every situation. Endorsed by Dr. Sears, too.
