The aim of this paper was to point out the significant role of emotions in children's artistic expression. Art activities favor the overall children's development and this can be progressed with quality and appropriate incentives from educators who recognize the value of children's artistic creativity. Children react to everyday situations driven by emotions, so they create according to current emotions, thoughts and interests. As the child develops and grows, he also goes through four developmental stages of artistic expression, starting from the simplest drawing up to the realistic representation of objects. When drawing, children pay the most attention to lines, colour and content, because through these three determinants of the drawing, they can most faithfully express their emotions. Apart from the fact that children's emotions are manifested in the drawing, art works on them by turning their negative emotions into positive ones and making them happier. The very process of artistic creation brings out the best in a child, therefore the process is much more important than the product itself, i.e. finished drawing. Collecting thoughts and feelings and transferring them to paper requires preparation and a certain amount of time in order to reach a finished children's drawing. Children do not like to leave drawing unfinished, so they will rather set aside as much time as is needed to draw everything they have imagined. A group of ten preschool aged children can be given the same task - to draw a certain vase with flowers that is placed in front of everyone, but after the activity, ten drawings with visibly different vases and different flowers would certainly be exhibited, exactly because the children do not reproduce reality, but draw according to their own experience and feeling, which differs from child to child.
