This paper analyzes the role of educators in fostering peer support and peer relationships in early childhood education settings. Particular focus is placed on the impact of peer relationships on children's socio-emotional development and the creation of inclusive communities. Contemporary and inclusive approaches to education recognize each child as a unique individual within their own culture, while simultaneously emphasizing the importance of children's collective interactions in building a culture of belonging and identity. The paper analyzes how children in preschool learn to recognize and accept others' needs, respect differences, and build relationships based on care and mutual support, with peer support playing a key role in social inclusion and inclusive education. The role of educators is significant in creating conditions for the development of close relationships among children by shaping both spatial-material and social contexts. The paper also examines the legal foundations of inclusive education, modern paradigms, and cultural theories, as well as the characteristics of peer support, socio-emotional development, play, peer relationships, and risks of social exclusion. The final section focuses on educators' competencies and strategies for promoting peer support and preventing social exclusion.
