Buying this idea really requires a fundamental reorganisation of how to relate to children! I think it's a complicated area, and the research is certainly confusing at times and more needs to be done.
I wonder how you see this happening in an ideal world. Personally, I "praise" my DD3 in the same way I "praise" adults. That is, I don't really "praise" at all, but I do express my feelings honestly and sometimes in a complimentary way. So for me I think changing how I talk to DD would necessitate changing how I talk to
anyone. It's a pretty daunting prospect.
