From the folks at Media Wise (www.mediafamily.org):
Research proves it: "Self discipline is twice as strong a predictor of school success as intelligence. We need to help parents foster this trait."
Hmmm... the author speaks a lot about consistency in setting limits. This sounds like it might be very Love and Logic friendly.
These folks have a website named after a new book they just released called Say Yes to No. http://www.sayyestono.org/
Of course they are a little heavy on "enforcing consequences" when Love and Logic would use language like "allowing children to experience the consequences of their own choices." Howvever... consistency, not rescuing, helping kids learn responsible behavior... that's all Love and Logic!
