Here is a fascinating, thoughtful and informative article, Even Babies Discriminate: Nurtureshock. It is well worth a careful read, and also worth calling attention to in it's own thread.

The article is research based, but not technical. It assumes you have read at least some of the lay literature on developmental psychology, or have some basic understanding of issues around early childhood development.   If you are a parent or educator, especially of very young children, it offers some very good advice worth considering.
