The Everyday Parenting Toolkit: The Kazdin Method for Easy, Step-by-Step, Lasting Change for You and Your Child

I already reviewed it here.

Better than numerous books on the issue that I and my wife have read over the years - among them

• Jesper Juul's 'Your Competent Child: Toward A New Paradigm In Parenting And Education'

• Tom Hodgkinson's 'The Idle Parent: Why Laid-Back Parents Raise Happier and Healthier Kid'

which are also good and have different focus but which didn't as significantly alter my behavior in response to reading them.
