The purpose of our study is to investigate how preschool teachers work with children in need, how to stimulate children in language and social interaction between preschool teachers and children. The study is based on the following questions; “What conceptions do preschool teachers have about children in need of special support?” and “What strategies are pre-school teachers using in order to promote children's social and language development?”. In this study, we have chosen Vygotsky’s concepts of zone of proximal development or sociocultural theory as the starting point and previous research that concerns our area. We have chosen to conduct a qualitative survey in the form of interviews with six preschool teachers in two schools. Starting point was to use our interviews with preschool teachers. Our examination shows that interplay between preschool teachers and children has a major impact on children´s development, to become an individual, to function alone and even with others. This is done by preschool teachers’ attitudes and beliefs in how they meet and talk with children and how the conditions are met. In the result, we realized that it is important that preschool teachers create good conditions for all children regardless of their difficulties. It was about how preschool teachers have to be efficient to ensure capture of children’s difficulties in time to help them to become independent individuals and to feel included together with involvement in the children’s group. It was about how preschool teachers organize the environment and materials in a way that would benefit all children’s learning and development in different contexts so that all children get the same opportunity worthy and to feel confident in the group of children.
