Based on lectures given by Dr. Montessori, The Absorbent Mind is an analysis of the physical and psychological aspects of a child's growth during the most significant period of life, birth to three years. During this period, the child learns motor coordination, language, and social skills, and establishes work habits and routines that set patterns for life. Dr. Montessori illustrates the mental powers of children that enable them to construct all aspects of human personality.
