I just wanted to let you all know that you can get free booklets from the United States Department of Agriculture. I recieved mine a few weeks ago and they are pretty cool. It's called the Natural Inquirer. They have several different issues. I beleive you have to order at least 5 of each but that allows you to share with other parents. Here is the address: http://www.naturalinquirer.usda.gov/educators.cfm
