Why expression matters in childhood

Before language fully develops, children rely on play, drawing, and imagination to communicate what they feel inside.

Have you ever felt like there is a vortex of emotions inside you, but no amount of words seems to be enough to properly explain it? If this is how you, as an adult, with all your advanced language and social skills, can sometimes feel, imagine how difficult it would be for a child, growing, learning, and feeling those emotions with no past experience of how to express them.
