Owen is four years old and lives with his adoptive mother and father. Owen was adopted at three months; his biological mother was fifteen and could not care for him. Owen recently started preschool and tends to cry for about ten minutes when his adoptive mother drops him off with his teacher. Reading usually helps to calm Owen, and he enjoys explaining what is happening on each page when an adult reads a story to him. Although Owen struggles to put on his coat during winter, he can put on his pants and shirt independently. Describe the developmental stages of preschool (4-5-year-olds)
