Excerpt from The Mental Development of a Child, Vol. 3: October, 1896The period of infancy is said to extend over the first two years of life. In order to give an introductory outline Of the move ment and direction of development, I have subdivided infancy into four periods, each of which is characterized by the vigorous growth of some form of activity.
