Socialization is a process during which children and young people are introduced to a particular culture, acquire appropriate attitudes and values, learn different life roles and develop acceptable social behavior. The main task of the socialization process is related to the transmission of the value system to the younger generation. This paper, entitled "Socialization of children with disabilities in preschool institutions", points out the obstacles, opportunities and opportunities for socialization of children with disabilities within preschool institutions. Full social integration of children with disabilities is impossible without improving their quality of life, which means full access to knowledge, education and cultural values that make up their personalities and their ideas about the world, as well as full participation in all forms of social and cultural life that is important for young children. It is especially important for children with special needs. No child is born with an innate skill to understand social skills, and children with special needs may need more time and effort to cope. With proper socialization, a child can learn how to communicate in the world and enjoy social situations. If a child is not socialized properly, he will struggle with these everyday things. They will not know how to share or set boundaries, which is necessary for building healthy relationships. As a result, they will struggle to establish meaningful connections with their peers that is most commonly seen within preschools. Children with developmental disabilities or special needs may struggle to interact with their peers. Every child with special needs is different. And each type of disability or need should be treated differently. Preschool institutions can change each child and gather insights about them, which they will then be able to share with parents and thus jointly help the child in his social interaction. All of the above is presented in detail within this paper.
