Becky! These articles were also very helpful as far as how much, etc.
P.S. Does anyone remember the episode of Punky Brewster, when Punky's friend and sibling are at the house, and the sibling drinks some of a product under the sink, and the friend doesn't know how to help because she can't read the label?? Anyway, I was thinking about that, it obviously made a big impression on me...
