The Dr. Spock Company: Expert parenting and children's health advice and information.
One of the best-selling books of the 1950s was one that my mother read (along with millions of other mothers and mothers-to-be). It was by a certain doctor, and it was about raising children. Well, here it is, over forty years later, and this fine gentleman is still around, sharing his knowledge with yet another generation of mothers.

The site is called DrSpock.com and is the online site of Dr. Benjamin Spock. Here you can find out just about anything relating to raising children, from being pregnant to raising a preschooler and beyond. This educationally-based site has topical news and information, message boards, advice sections, and a place where you can ask questions of a panel of pediatricians.
