“Parents should also question much of the contemporary emphasis on special materials and equipment for learning in a child's environment. A clutter of toys can be more confusing than satisfying to a child. On the other hand, natural situations, with opportunieties to explore, seldom overstimulate or trouble a small child. Furthermore, most children will find greater satisfaction and demonsstrate greater learning from things they make and do with their parents or other people than from elaborate toys or learning materials. And there is no substitute for solitude - in the sandpile, mud puddle, or play area - for a yound child to work out his own fantasies. Yet this privilege is often denied in our anxiety to institutionalize children.”
