Co-authors and co-parents, Kathleen Ann Harper and William Paul White are the couple behind Signs of a Happy Baby and an integrated online learning center for parents. Since 2004, William and his network of instructors have taught fun, interactive, and educational sign language classes and playgroups to more than 13,000 parents. William's brick-and-mortar programs are offered at locations throughout the San Francisco Bay Area, including Kaiser Permanente, Dignity Health, Sutter Health, Blossom Birth, Families@1st at Cisco Systems, and many others. Always fascinated by how people learn, William earned his Bachelor of Science degree from the University of California, Santa Cruz, in psychobiology, the study of behavior from a biological perspective. Kathleen is a certified life coach and the author of the Amazon bestseller The Well-Crafted Mom. In her groups and one-on-one coaching practice, Kathleen integrates coaching support with creative activities to help moms manage the transitions and challenges of motherhood. She holds a Bachelor of Arts degree from San Francisco State University in integrative healing, a specialized major incorporating studies in psychology, philosophy, religion, holistic health, and kinesiology. Kathleen and William live in the San Francisco Bay Area with their two sons (who both still sign).
