When she was a preschool teacher, Carol Stock Kranowitz was curious about why certain young children responded in unusual ways to sensations that did not bother most kids. She learned about sensory integration and processing and wrote the first edition of The Out-of-Sync Child in 1998 to help parents and teachers understand and support kids who may be over-sensitive, under-sensitive, confused, poorly coordinated, and/or challenged in other mystifying ways. In April 2022, the third edition of The Out-of-Sync Child was published with a revised subtitle: Recognizing and Coping with Sensory Processing Differences. The word "Differences" replaces "Disorder," to be more inclusive and appreciative of the diverse ways individuals manage and use ordinary sensory messages coming from their bodies and the environment to function smoothly in daily life. Several books and materials have received awards from Mom's Choice, Creative Child magazine, and Learning magazine. Carol is a graduate of Barnard College of Columbia University and earned an M.A. in Education and Human Development from the George Washington University. She lives in Maryland with her partner Mark and has two sons and daughters-in-law and five grandchildren. She writes a column in the quarterly magazine, "Autism Digest." She plays the cello, walks three miles a day, and answers every email.
