From the Author
Dr Robert Bucknam, M.D. acknowledged that his On Becoming Babywise is a work in progress in a 1998 article (the entire article by Dr. Bucknam, M.D. can be seen at babywisebooks.com): "We realize that some statements found in the first edition needed further clarification and in some cases, minor corrections." Dr. Bucknam, M.D. points out that these clarifications and corrections are now in the latest version. On Becoming Babywise has four prior versions that do not have all the clarifications, corrections, and latest medical update-- this version (with the blue strip at the top of the cover and isbn 1932740082) is NOT the latest version. The current and most recent version is the 5th edition, February 2012 (it has a pink strip at the top of the cover). We highly recommend ONLY purchasing the newest and most current version of On Becoming Babywise (isbn 1932740139). It has a new chapter, several important revisions, the latest in medical updates, and is 19% longer than the former version. In becoming one of America's leading infant management guides, On Becoming Babywise has continued to improve its methods and practices throughout its 30 years and this latest version is the result of all the best over the last three decades.
