I've never heard of him before but stumbled upon this book while browsing Amazon, UNCONDITIONAL PARENTING: Moving from Rewards and Punishments to Love and Reason.
I may be a little premature here as I'm only half way through, but I've read lots of parenting books and this is without doubt the best, ever! So if you're thinking about getting one please make it this!
I'd love to hear any opinions you may have, those of you who have read it.
