This article focuses on the early childhood years, from 2 to 5 years of age. There are over 12 million children in this age range in the United States, many of whom face a number of challenges. In this article we discuss cognitive, language, motor, and social development, including relevant theories and major language and motor developmental milestones. We also discuss several family and environmental factors that influence development, including attachment, parenting, working parents, and poverty.
