Communication is an important means by which we create acquaintances, learn, express thoughts and feelings. Quality communication is the foundation for good interpersonal relationships and cooperation. A man learns while he is alive. We show the first signs of communication at birth. The child initially develops communication with the parents. Later, this communication develops in interaction with the environment. During life, many communication skills are developed through education in educational institutions. Children communicate in a specific way. They adapt to the situations around them and develop their communication skills. In addition to differing from adult communication, children's communication also differs in terms of age and characteristics that are specific to each child. The theoretical part of the paper includes communication skills, their forms and the development of communication skills in early and preschool children. The paper also deals with the communication competencies of educators, which are extremely important. The empirical part of the paper contains research on competencies, attitudes of educators related to children's communication skills, but also themselves, and the development of children's communication skills. For the needs of the research, a survey questionnaire was created exclusively for the purpose of research on a sample of 72 respondents. The aim of this research is to compare the communication skills of children of early and preschool age, ie to determine whether there are differences and what are the biggest differences.
