The Proven Program for Raising Responsible Children
Ratings1
Average rating4
Very quick read with lots of very useful ideas and information.
It's really just an introduction, though. The book is full of examples on how to apply the techniques in different situations, but they don't really cover each technique for each age group. I think some additional conversation around edge cases would also be useful.
Even so, this seems to me to be a very solid introductory text for non-punitive parenting approaches.
