This document consists of a compilation of three separate 4-page brochures by the same authors: (1) understanding babies and toddlers; (2) understanding three to six-year olds; (3) disciplining preschoolers. The first brochure covers bonding and attachment, infant temperament, patterns of growth, and the characteristics of children during the first, second, and third years of life. The second brochure describes characteristics of 3-, 4-, and 5-year-olds and ways of promoting the child's self-image. The third brochure points out characteristics of 3- and 4-year-olds that should be considered in disciplining them; describes a way of thinking about discipline that differentiates between rigid enforcement, permissive discipline, and developmental discipline; advises parents to set limits, be a model for children to copy, and use natural consequences; points out causes of children's misbehavior; and urges parents to teach their children ways to handle jealousy, anger, and aggression.
