This study concerns a group of foreign parents' experiences with Swedish preschool. The purpose of the study is to gain an understanding of the foreign guardians' experiences of the phenomenon. Semi-structured interviews are conducted with six informants, and the results of the interviews are compiled and linked to theoretical concepts in the analysis. The concepts that I have chosen to define are culture, Swedishness (svenskhet) and life-world. In the discussion section, I link the results to previous research on the preschool's work on diversity. The results show that the custodians experience a lack of collaboration between preschool and home and a lack of communication. Cultural differences lead to prejudice, and negative attitudes and language deficiencies give custodians a sense of exclusion.
