My two favorite parenting books are "12 Simple Secrets Real Moms Know: Getting Back To Basics And Raising Happy Kids" by Michele Borba and "The Secret of Parenting: How to Be in Charge of Today's Kids -from Toddlers to Preteens- Without Threats or Punishment" by Anthony E. Wolf.
The first book is easy to go through and you can choose which of the 12 secrets you want to do in any order. She uses lots of stories from real mothers that help relate to each secret and make it easier to remember. The book is divided into two parts. First part is titled- "How can a real mom give her children love that lasts for always?" The second part tells us the secrets.
The second book reads very quickly and will most definitely make you laugh at some point. It has helped so much with stopping all those nasty little things that can sometimes come out of children's mouths: "I hate you!", "You're mean.", "Why do I have to...?", all the whining and backtalk that comes as they get older and try to seriously challenge you, etc.
I also like the website by Sharon Silver. She has a book as well, but the articles on her website are really great little gems of parenting advice. I haven't read her book yet. http://proactiveparenting.net/
