What is a normal child like? Does he just eat and grow and smile sweetly? No, that is not what he is like. The normal child, if he has confidence in mother and father, pulls out all the stops. In the course of time, he tries out his power to disrupt, to destroy, to frighten, to wear down, to waste, to wangle, and to appropriate . . . At the start he absolutely needs to live in a circle of love and strength (with consequent tolerance) if he is not to be too fearful of his own thoughts and of his imaginings to make progress in his emotional development.
