I have to post too about this show. I think this is a very educational show and yes these are just Jo's opinions on how child rearing should be done, but the techniques do work.
I too would like to see what happens when it doesn't work though. Also, I'd like to see some bigger problems like a biting child worked out. What if the kid DOESN'T stay on the naughty spot? I also feel much better about our parenting styles. There are some parents out there that don't seem like they have ever read a parenting book. In my opinion, having children comes naturally but bringing them up is hard work and natural instincts only take you so far.
