As a teacher for 25 years, Carol Kranowitz, M.A., who holds a Master's degree in Education & Human Development, Special Education from The George Washington University, observed many young children with Sensory Processing Disorder. To help these "out-of-sync" preschoolers become more competent in their work and play, she studied sensory processing theory, learned about some differences between SPD and ADHD, and steered the students into appropriate early intervention. In her writings and workshops in the United States and abroad, she explains to parents, educators, and other early childhood professionals how sensory challenges play out – and provides fun and functional sensory strategies for home and school. Her two most popular books, The Out-of-Sync Child and The Out-of-Sync Child Has Fun, together, have sold 1 million copies. Carol's latest book The Out-of-Sync Child Grows Up has just been published.
