Communication is the foundation for interaction among people, the development of social relationships, and understanding the enviorment around us. Research and study of children's verbal and non-verbal communication, help us understand how children percieve and react to the world around them. Verbal communication, which includes speech, develops through interaction with adults and peers. Non-verbal communication, which involves the use of non- verbal cues, such as gestures, eye contact, and facial expressions, plays a crucial role in eary childhood as it allows children to express their needs and desires before they have developed verbal skills. The family, environment, and preschool institutions, especially preschool teachers, play a fundamental role in the process of acquiring and developing both verbal and non-verbal communication in children. The purpose of this work is to analyze scientific literature and provide insight into the development of children's verbal and non-verbal communication up to school age, with a focus on the importance of the child's interaction with family, environment and preschool institutions. The work also highlights the importance and significance of improving the communication interaction between preschool teachers and children.
