I was not familiar with Dr. Karyn Purvis until I visited Christine at her blog yesterday and watched her videos. Dr. Purvis is the director of the Institute of Child Development. I feel Dr. Purvis is a great example of what Nancy Thomas calls the correct combination of Grandma and Arnold Schwarzenegger. Gentle and yet strong. I love that. I am not saying I agree with all her views. I am not familiar enough with her work to say this. But I do love the two videos on Christine's blog.
