The Period of PURPLE Crying® is the phrase used to describe the point in a baby’s life when they cry more than any other time. It is a new way to help parents understand this time in their baby’s life, which is a normal part of every infant’s development. The Period of PURPLE Crying begins at about 2 weeks of age and continues until about 3-4 months. There are other common characteristics of this phases, or period, which are better described by the acronym PURPLE. All babies go through this Period it is just that during this time some can cry a lot, some far less, but they all do go through it.
Dr. Ronald Barr, Developmental Pediatrician and World Expert on Infant Crying, explains the Period of PURPLE Crying Program.
