Developed and refined by two successful pediatricians, the "Jassey Way" boasts more than a 90% success rate of getting children to sleep through the night in their first 4 weeks of life. A safe and proven technique, the Jassey Way uses a feeding schedule that allows newborns (and their parents) a full night's sleep at a younger age than other sleep training techniques. | The Newborn Sleep Book by Lewis Jassey, Paperback | Indigo Chapters
