Promoting interactions between preschool children is an important topic because peer social interactions provide a crucial context for children's development. However, many young children experience difficulty with peer relations, particularly children with disabilities. Indeed, children with disabilities have problems with peer interactions beyond difficulties expected based on developmental level. For children who have great difficulty interacting with peers, early educators must plan, implement, and monitor interventions to promote social interactions. This article describes the importance of peer social interactions for children's development and then suggests how early educators can intervene by: (1) setting up the environment; (2) teaching children social interaction skills; and (3) involving peers in social interaction interventions. Finally, general guidelines for implementing these interventions are provided. (Contains 6 tables.)
