The author looks at creative literary activity in its initial form of a dialogue between the narrator and the listener. The dialogue stimulates literary development in preschoolers, development of their intellectual and communicative abilities. Findings of an educational experiment prove that development of subjectness in a preschooler occurs in joint literary activity with another child or an adult. Changing of role positions in the dyad "the narrator - the listener" (with an adult and later with another child) is a precondition for development of a preschooler's creative literary activity.
