Margaret Wise Brown said this quote
“ In this modern world where activity is stressed almost to the point of mania, quietness as a childhood need is too often overlooked. Yet a child's need for quietness is the same today as it has always been--it may even be greater--for quietness is an essential part of all awareness. In quiet times and sleepy times a child can dwell in thoughts of his own, and in songs and stories of his own. ”
