The purpose of this study has been to investigate the concepts of children in need of special support, inclusion and how preschool teachers work with an inclusive approach in preschool with children in need of special support. The research questions that have formed the basis of this study have been 1) What does the preschool teacher's definition of the concept of children in need of special support consist of? 2)What does the preschool teachers' definition of the concept of inclusion around children in need of special support consist of?  3) How do the preschool teachers describe what an inclusive way of working looks like in preschool? 4) What previous experience do preschool teachers have of working based on an inclusive approach?

The study was conducted with qualitative interviews of six preschool teachers where the collected data material was analyzed with a thematic analysis. The theory that the study leans towards is soft and hard inclusion as well as the compensatory and the critical perspective. The result showed that all preschool teachers had a consensus of definition of inclusion with children in need of special support. It was described as allowing all children to be part of a community. Furthermore, they had a similar view of the definition of children in need of special support. They believed that it was children with and without a diagnosis, children who need extra support to make everyday life work. Preschool teachers describe an inclusive way of working as an adapted approach, an adapted environment, and activities as well as certain individual-adapted methods. They described that inclusion work is based on children being involved and that the activities are based on democratic values ​​where everyone's equal values ​​are considered. All preschool teachers had a lot of experience of an inclusive approach, but they felt that there were some difficulties.
