Emotions are an important part of the overall development of everyone, from the very birth onwards. From birth, the child enters direct interaction with his environment in which there are certain factors, above all important as models that the child will later imitate: mother and father. Studies have shown that the child forms an inseparable bond with his primary caregiver, in this case the mother, whose facial expressions he directly observes and later imitates. The ability to outsource emotions is a complex process that takes place gradually. Artwork as a means of externalization of emotions provides a kind of channel through which the child releases the internal state and transfers it to paper. The child while drawing feels freedom and develops self-confidence. Children of different ages go through several developmental stages that should be borne in mind when assessing or analyzing a children's drawing. Karen Machover introduced a projective technique in the drawing of a human figure that evaluates the structure and function of personality, but the drawing, when its clinical value was shown, was introduced into a routine procedure and work with patients of all ages. The analysis of the drawing takes place by asking certain non-suggestive questions from which the whole story of the patient's condition develops. Gradually, detailed methods of interpretation of the drawings of a particular part of the body were developed, and the subject of the analysis became the size of the figure and its position on paper, perspective, symmetry, line, shading. The development of psychotherapeutic directions and a more humane approach influenced the drawing, in addition to the diagnostic agent, to become a therapeutic tool. Artistic expression allows children to express feelings that are otherwise difficult to verbalize, especially sadness, fear, anger, and happiness. The expression of emotions helps children to release accumulated emotions, reduce the feeling of helplessness and master their condition and environment, thereby reducing their sense of vulnerability.
