Look at the pictures of Madonna and Child, and you will even _see_ it.

It is from this center that it draws all things unto itself, winningly, drawing love for the soul, and actively drawing in milk.

The same center controls the great intake of love and of milk, of psychic and of physical nourishment.
And it is from the great voluntary center of the lumbar ganglion that the child asserts its distinction from the mother, the single identity of its own existence, and its power over its surroundings.

From this center issues the violent little pride and lustiness which kicks with glee, or crows with tiny exultance in its own being, or which claws the breast with a savage little rapacity, and an incipient masterfulness of which every mother is aware.

This incipient mastery, this sheer joy of a young thing in its own single existence, the marvelous playfulness of early youth, and the roguish mockery of the mother's love, as well as the bursts of temper and rage, all belong to infancy.
