The National Center on Shaken Baby Syndrome announced they have expanded their website to be the most comprehensive source on Shaken Baby Syndrome/Abusive Head Trauma (SBS/AHT). The site includes new information about the evidenced based SBS/AHT prevention program, the Period of PURPLE Crying. The Period of PURPLE Crying® program incorporates 25-years of research on normal infant crying to help parents and caregivers understand the frustrating features of crying in infants that can trigger shaking or abuse. According to the National Center, SBS is the leading cause of death in abusive head trauma cases. An estimated 1,200 to 1,400 children are injured or killed by shaking every year in the United States with actual numbers possibly much higher as many likely go undetected.
