Want to help other families? Here's a free and simple way: there are so many books out there, it can be daunting to choose. If you've read a book about eating disorders that helped:
Review it or add it to the list on the F.E.A.S.T. site. http://feast-ed.org/bookreviewsbyparents.html
Another important place to write reviews is on the Amazon.com site. These reviews really do matter to buyers, and are widely distributed.
One quirk of Amazon is that you can't write reviews for a book if you didn't buy it AT Amazon. For that reason I can't review my all-time favorite book for parents: "My Kid Is Back" by June Alexander. I highly recommend this book, and ask you as a favor, if you have bought it there and found it useful, go review it: My Kid is Back.
