A child asks questions without inhibition. This is wired into them as a natural response for how they are meant to learn about the world around them. The good parent will understand this need to grow. They nurture the child to ask and seek continuously; assuring the child will come into fullness of understanding.
Other parents become impatient with the child, stifling their curiosity. They begin to hush that child, discouraging the many questions. Eventually they begin fill the child’s mind with their own understanding. Inhibited, the questions of a child finally stop.
