Unconditional Parenting by Alfie Kohn

The author of Punished by Rewards and The School Our Children Deserve builds on his parenting theories of working with children rather than trying to control them, argues against practices that teach children that they must earn a parent's approval, and presents techniques that promote desired child qualities through unconditional support. Reprint. 30,000 first printing.

This could easily have been a 50-pager.
Main take-away: “If you respect your kids, they respect you.” Although, it was presented from the other angle: “Don't be an a-hole, or your kids will be sh't.” Stupidly obvious and repetitive, even if it made sense.

Interesting perspective on parenting. Probably a bit too extreme, a bit too preachy, and the author spends far too much time on the “wrong” practices, and far too little on what “good” parenting actually looks like, but definitely worth a read.
I would be interested to read a similarly persuasive book(s) from the “behaviourist” camp to form a more informed opinion - especially that in general I'm implicitly biased against behaviourism - any recommendations would be much appreciated!
