The aim of this study is to observe Swedish preschool children in their natural habitat and without any intervention. Four different observations are made and thereafter analyzed. Throughout the whole study the subject of interest is the children's communication in their play. Children can communicate with each other in various ways, for instance with speech and without speech, i.e. with their physical language, aesthetic and multi language. Their abilities are astonishing, and in all four observations, they find ways to communicate with each other and kept the play continue. In some of the observations, small conflict situations appear, but with the help of their communication abilities, with or without the language, they manage to solve their problems. Therefore I conclude that preschool children's ability to communicate throughout the play is accomplished, and continues without the help of the adults.
