Gender stereotypes in the early children's development are deeply rooted in the social and cultural forms. Children, since their early ages, learn the gender standasdized knowledge and behavior. This is all influenced by the family, educational institutions such as day-care and schools, and mass media. Ceratin toys, cartoons and books meant for children are also keeping the existing stereptypes in the aspect of male-female relations. In this paper/thesis we consider the theme of gender stereotypes of the girl character in the early and mid 20th century novels, by analyzing selected novels: Zlatni danci by Jagoda Truhelka, Iskrica by Mate Lovrak, Lažeš, Melita by Ivan Kušan, Lopovska uspavanka by Pavao Pavličić, Dnevnik Pauline P. and Drugi Dnevnik Pauline P. By Sanja Polak and Brbljava Iva by Jelene Pervan. In the analysis of the girl character we have described and written quotes with which we confirm the way the girls are formed by the example of typical femminine and masculine personality traits. We also investigate if these novels support gender stereotypes and if they have changed through time.
