Through intellectual, emotional, perceptual and social developmental factors we gain insight into a child’s developmental stage. Various difficulties caused genetically or imposed through interactions with the environment can significantly affect a child's development and progress. In child psychotherapy, it is very difficult to achieve good verbal communication, so it is important to include other instruments that can serve the purpose of communication. One of the popular substitute instruments is artistic expression, which is used not only for therapeutic purposes but also as a diagnostic tool. Visual expression can be an aid through which a child can communicate non-verbally and thus offer an overview of his inner state. Drawing is like a play, an immanent activity for children through which they can express their fears, hopes and desires, of which they may even be unconscious. Children love to draw and their drawings in therapy talk about possible reasons for their frustration, aggression, or conflict. Interpretation of children's drawings is carried out on many levels. The drawing helps us to explain more precisely what the child is suffering from. It can be an indicator of cognitive, emotional and motor development, aggression and various traumas that have occurred after experiencing abuse. When analyzing children's drawings, we notice the appearance of specific symbols and artistic elements and the way in which the child draws certain motives such as the house, human figure and family, which can be helpful in diagnosing problems. Based on the symbols that often appear in the drawings, various tests have been designed to assess intelligence, cognitive, perceptual and associative abilities and the child's character traits. Through the recognition of signs and symbols that indicate the need for art therapy, the child is assisted in the form of art workshops so that the drawing can be better analyzed, and the child can be supported in solving the problems he faces. Art therapy in children encourages personal development, increases self-understanding and helps in emotional recovery.
