" many people in our society, including children and youth, are touch-starved. Healthy touch is not well understood. We actually have schools where tiny toddlers whose impulse is to run up and hug a classmate or teacher are told not to touch; in return, the teachers and other caregivers are not allowed to touch the children. But it’s simply unhealthy for a three-or four-year-old child to go eight hours without touching or hugging or playfully wrestling with another person. "
