The Period of PURPLE Crying starts when your baby is around 2 weeks old and generally ends when they reach their 3- or 4-month birthday. This idea that it’s a finite period — in other words, it has an end — is meant to give new parents hope that the unexplained crying won’t last forever.
The program approaches Shaken Baby Syndrome (SBS)/ Abuse Head Trauma (AHT) and infant abuse prevention by helping parents and caregivers understand the frustrating features of crying in normal, healthy infants that can lead to shaking or abuse.
