I didn't really learn anything new from this book. I was also disapointed in the authors lack of comprehensive, cross-cultural, and/or well researched information on the benefits of co-sleeping and extended (beyond 1 year) breastfeeding (...never mind the fact that both the World Health Organization and the Surgeon General has recommended breastfeeding for a minimum of two years.) I would strongly recommend the Sears' Discipline Book, and the Sears' Parenting the Fussy Baby and High Need Child over Positive Discipline.
