I know about it, mostly through following Janet Lansbury on facebook. I like a lot of things about it, and agree with allowing your child to be independent early on, and letting them develop at your their own pace. I like her thoughts on not "walking" your child before they are ready to walk. I also talk to all my daycare kids like I would with an adult. How else would I talk to them? The more you talk to them, the more they understand.
