I have noticed a lot of change both for better and worse. Alfie Kohn used to be very big as was NFL with very little dissent and a lot of attacking. I sometimes laugh now at what people see as attacks because it is rare for it to get as bad as it was when very few ideas were accepted as gentle. I think some of the change came because as kids get older most children do go through a stage that throws their parents for a loop and humbles them. Or, it's hard to see well adjusted school age children everywhere and still hold yourself above everyone else.
I do miss the hard core NFL and Kohn followers though because their ideas helped me question my own parenting. It would be nice to see a bit more balance. I feel like we are currently seeing backlash against the hardcore that was in control before.
