The author describes the love idyll of two boys and a girl, who are from three and a half to five years of age, in the form of a novel. He wishes to bring before psychiatrists what they always refuse to believe, namely, 'that the first infantile expressions of sexual sensations in children are generally as old as, say, the first attempts to walk, if not older'. The work fulfils what it promised. It shows that the sexual instinct manifests itself in infancy, and can be expressed in the mental sphere in 'bashfulness, caring for others, willingness to make sacrifices, and chivalry', just as in adults.
