But more and more, studies show that children need "rough and tumble" outdoor play in order to develop their sensory, motor, and executive functions. In this important book, a pediatric occupational therapist explains why unrestrained movement and outdoor play are vital for children's cognitive development, and offers fun, engaging activities to help ensure that kids grow into healthy, balanced, and resilient adults.
