The most common prose type in children’s literature is the children's story which is divided into three subtypes: fairy tale, fantastic story and realistic children’s story or short story. What distinguishes these subtypes is the presence or absence of the fictional, the miraculous, the unreal. Based on this, fairy tales are characterized by the coexistence of the realistic and the unrealistic, where these two worlds do not contradict each other; fantastic stories build an unreal world on the real world which is the result of the subconscious of the characters; while realistic stories take place entirely within realistic frameworks, so there are no miraculous elements present. Realistic children's stories describe the lives of real children and real situations they go through their childhood and this paper will be about the realistic children's stories by the authors Mato Lovrak and Zlatko Krilić. The aim of the paper is to analyze and compare their realistic stories by following categories (theme, style and language, characters and purpose) and to point out its development from Lovrak’s era to the modern era.
