Humor in children becomes an important topic for studies, but still remains underestimated. There are several directions of children humor research that need a thorough critical analysis. The purpose of the study involves identifying the main trends in the study of the sense of humor in children in actual scientific works. The main method of the critical review was a bibliographic analysis of sources published since 2000, found in the international citation databases Scopus and Web of Science using the VOSviewer tool. This tool made it possible to identify the total number of publications for the search query “humor” and “children” with further identification of keywords. When filtering keywords, clusters were obtained that form conceptual spaces around which the topics of research for children humor were formed. The search for the specified conditions found 624 records in the Scopus database and 380 records in Web of Science. A review of studies in international citation databases showed that publication topics are grouped into clusters reflecting the psychological, psychotherapeutic, clinical and humoral aspects of the study of the comic in childhood. Humor in childhood is considered either as a developing phenomenon or as an independent value inherent in childhood.
