This paper describes various theories of creativity, provides relevant data on emotions and artistic creativity of the child. Children's art is the basic means of communication between the child's inner world and the educator / parent. With the help of artistic expression, children express their emotional state and experience of the environment that surrounds them. For the purpose of the paper, qualitative research was conducted to determine the level of emotional intelligence of children of early and preschool age and to observe art techniques, motives and colours that children use in their artistic expression. The results showed that children possess a high level of emotional competence, recognize different emotions, and possess the skill of expressing them. Through children's artistic expression we can see how each child is an individual, with different inner experiences of the environment in which he is, which allows us an insight into child development, its interests, and needs, and thus provides the educator the opportunity to respond properly and encourage growth and development of the child into a positive, competent and whole person.
