A child's artistic expression during preschool period refers to artistic thinking and because of that it directly depends on the child’s cognitive development. A child’s integral development rests on the importance of integrated action in all aspects of education. This is what makes educational work with the children of the earliest age very complex. Children grow simultaneously in intellectual, emotional, physical, social and aesthetical aspect. They use the natural potential of their being and the interaction with the outside world to develop their abilities. The age from 6 months to 3 years represents a crucial period in the lives of preschool children. Today’s society expects certain procedures in the upbringing of preschool children. Children up to year 3 experience the doodling phase when they take the writing, drawing or painting tools in their hands and leave traces on the paper, wall, floor, clothes or themselves. The preschool period encourages the development of perception and hand motors skills which will serve as the basis for the next period’s artistic expression. This artistic expression is the beginning of their contact with the world of art, different artistic tools and techniques. Visual activities in this period relate to the acquisition of visual, tactical and auditory experiences that create sensory integration but also develop initial sensitivity for the notion of a line, colour, volume and space. This is how children are introduced to the elements of the visual arts.
