Adults can say, "Bao Xiao, you drew a straight line (curve)." "Bao Xiao, you drew a big circle, that's great!" Let him learn self-expression from hands-on and get self-affirmation from encouragement. Adults can also make do with encouraging Bao Xiao to change his graffiti action, draw lines with different lengths and thicknesses, and experience the relationship between action and graffiti.

2. Arrange a safe graffiti environment for Bao Xiao.

Let them doodle there freely. It is best to reserve a "graffiti territory" for Bao Xiao, and stick white paper (which can be calendar paper) on the surrounding walls according to the longest height of Bao Xiao's hand. You can also buy big drawing paper in the store, and you can change it into new white paper after painting). You can take a brush with Bao Xiao at a fixed time every day, or sit or stand, draw on the wall, and collect the pen as soon as possible, "let Bao Xiao go home and sleep with the brush", and supply materials and appliances suitable for Bao Xiao's graffiti, such as crayons, markers, oil pastels, pencils, etc. A short refill is not suitable for breaking better. In addition, black, dark blue, red and green pens with high chroma and low lightness are especially suitable for Bao Xiao, which helps Bao Xiao to find the difference between objects and backgrounds.

3. Let Bao Xiao feel and experience the changes in the environment.

As he grew older, Bao Xiao began to like the bright and changing environment. Adults should take Bao Xiao out to get in touch with the outside world and observe all kinds of things. Guide Bao Xiao to see with his eyes, listen with his ears, smell with his nose and touch with his hands, to understand things with all kinds of feelings, to enrich his imagination, and to accumulate experience for later expression with painting, language and action.
