Does anyone else use this? I wondered if I could find someone to enthuse with. I bought it because a child psychiatrist I know said that she worked with him briefly and he really knew his stuff. It's amazing. DS is an angel now, I'm enjoying him so much. Lots of it is stuff that I'd tried anyway (sticker chart, positive parenting, time out etc) but it was the specifics of exactly how to do it that I was sometimes doing differently to how Matthew Sanders recommends and my god, the change in DS is just fantastic. So does anyone else use it?
