The modern age offers us a wealth of information we receive through the media- through television, the Internet, books and picture books. The picture book, the first book in a child's life, plays an important role in the overall development of the child. Unfortunately, a large number of picture books encourages learning and the adoption of sex-stereotyped attitudes, and this can be observed in children of preschool age. Just a cursory inspection of the picture books come to the conclusion that most picture books promotes gender inequality. As such, they promote thinking that the boys, men, are still bolder, more interesting and more capable than girls and women, and girls and women are more sensitive, fragile and need to be "saved". Today's culture is a shared world of the blue and pink, so prevention of sexually-stereotypical thinking in children is greatly needed. The stereotypes have a negative impact on children's development, limiting their professional aspirations, shaping attitudes about their future parental roles, and even affect the characteristics of their personality. The purpose of this project is to show the extent of sexually stereotyped characterization of the characters in picture books and the attitudes about gender roles of preschool children (age of 6 and 7) in the older educational group in kindergarden Zrno in Virje.
