THE MANIFESTATIONS OF THE INFANTILE SEXUALITY

For reasons which we shall discuss later we will take as a model of the infantile sexual manifestations thumbsucking (pleasure-sucking), to which the Hungarian pediatrist, Lindner, has devoted an excellent essay.
Thumbsucking. - Thumbsucking, which manifests itself in the nursing baby and which may be continued till maturity or throughout life, consists in a rhythmic repetition of sucking contact with the mouth (the lips), wherein the purpose of taking nourishment is excluded. A part of the lip itself, the tongue, which is another preferable skin region within reach, and even the big toe - may be taken as objects for sucking. Simultaneously, there is also a desire to grasp things, which manifests itself in a rhythmical pulling of the ear lobe and which may cause the child to grasp a part of another person (generally the ear) for the same purpose. The pleasure-sucking is connected with an entire exhaustion of attention and leads to sleep or even to a motor reaction in the form of an orgasm. Pleasure-sucking is often combined with a rubbing contact with certain sensitive parts of the body, such as the breast and external genitals.
