Painting is a very important part of children’s development. Kids start to draw long before they learn to count, write, or read.
Before they can write the word "Mama," they can draw her shape. Drawing is the bridge between the physical world (Mom) and the abstract world of symbols (This mark on paper means Mom).
When kids draw, they aren't trying to be Picasso. Adults are bogged down by rules, techniques, and the fear of "bad art." Children don't care about perspective or realism, trends and scores. It is art in its most raw, honest form - pure unfiltered honesty.
