It has been around for a long time. It's only lately that it's getting more well known.
I hate to tell ya, people that AP actually have better behaved kids who are more independent and very well adjusted. We don't believe in not disciplining, we just use different methods, like I said.
My niece has been parented in a "traditional" way and she doesn't know how to control her emotions. She shouts because her parents shout and she doesn't listen to anyone, aside from me and my DH. We are very firm, but fair.
I believe in mutual respect. I will respect my child's needs and emotions and I expect them to respect me the same.
ETA: Nope, I don't hate to tell you actually! I'm damn proud when people comment about how well behaved Alex is!
