Dispelling Cry-It-Out Sleep Training Myths And What To Do Instead: A New Academic Anthology
This guide draws together evidence from psychology, neuroscience, anthropology, and human development to make a compelling case for why you shouldn’t be using or recommending crying-it-out sleep training techniques with babies.
Dispelling Cry-It-Out Sleep Training Myths and What to Do Instead explains what normal infant sleep is like and explores the history and context of cry-it-out sleep training methods for infant sleep.

The book ends with an in-depth exploration of alternative approaches to promoting good quality infant sleep.
