Learn about the Period of PURPLE Crying (PoPC), an effective intervention designed to educate parents on normal infant crying and coping strategies. Developed by Dr. Ronald G. Barr, PoPC has led to positive behavioral changes, reduced pediatric emergency room visits, and a 75% decrease in injuries related to Abusive Head Trauma (AHT) among participating parents. This evidence-based program is crucial for preventing AHT and supporting parents, especially in economically disadvantaged communities.
