Train yourself to observe in a methodical way. Many child therapists use art therapy techniques as part of their diagnosis and treatment, even though they may not have had formal training in this discipline. As with any technique, it is important to have a developmental framework for understanding a child's art, in order to ascertain its usefulness and meaning. Children delight in simply moving a pen or crayon around, taking interest in whatever appears. Children begin to outline forms within the scribbles.
Shapes appear to be random initially but gradually become familiar circles and squares.
By the end of this stage, children begin a drawing with a plan in mind and, if asked, will tell a story about a particular drawing. Children draw pictures that tell a simple story. We expect to see people with all their body parts in this stage, although the bodies may be distorted. Children can draw with a fair degree of realism that continues to improve with practice. During this time many children stop drawing altogether.
