Children's literature represents a special and important part of literature intended for children from a very young age to adolescence. Children's literature has many divisions and types, but its main characteristics are that it is written for children, that the characters are relatable to children (objects, things, people), and that it is defined as such by publishers and/or bookstores. Picture books are a type of children's literature and represent the most important and first book a child encounters. They are a fusion of the art of words and visual art. The contents of picture books can vary. In contemporary Croatian and world literature, increasing attention is given to the child as a character. The child character actively drives the plot and is at the center, with their concerns, problems, and desires taking precedence. As child characters are becoming more prevalent in children's literature and are presented to children as motivational texts, the question arises: do children have distinct opinions about themselves and their behavior? This work presents the results of research conducted in September 2023 with preschool children aged five to seven years. The aim of this research was to discover whether children have distinct attitudes towards the child characters in Croatian children's literature that they encounter through various oral forms of work in the context of language and communication development, as one of the fundamental areas within early childhood education and preschool curriculum. Additionally, it will explore children's perception of characters, i.e., their experiences with selected child characters, which forms the basis of this thesis.
