I read this book some time ago with mounting concern. As a parent and counsellor dealing with breastfeeding women, I have never seen a better recipe for lactation failure.Babies are not dogs to be trained to sit up and beg; they are helpless, immature little humans whose only way of communicating distress is through crying. Other mammals deliver young that are much more mature - newborn horses can stand, for example - human newborns are foetuses on the outside, bacause they have such big heads, and need to be treated as such.Readers of this book need to be aware that the authors draw their childrearing opinions from a fundamentalist reading of the bible, not from a pediatrics background.Many childrearing experts have condemned this book.
