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.[9] *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.[10] Pleasure-sucking is often combined with a rubbing contact with certain sensitive parts of the body, such as the breast and external genitals. It is by this road that many children go from thumb-sucking to masturbation.
Lindner himself has recognized the sexual nature of this action and openly emphasized it. In the nursery thumbsucking is often treated in the same way as any other sexual "naughtiness" of the child. A very strong objection was raised against this view by many pediatrists and neurologists which in part is certainly due to the confusion of the terms "sexual" and "genital." This contradiction raises the difficult question, which cannot be rejected, namely, in what general traits do we wish to recognize the sexual manifestations of the child. I believe that the association of the manifestations into which we gained an insight through psychoanalytic investigation justify us in claiming thumbsucking as a sexual activity and in studying through it the essential features of the infantile sexual activity. *Autoerotism.*--It is our duty here to arrange this state of affairs differently. Let us insist that the most striking character of this sexual activity is that the impulse is not directed against other persons but that it gratifies itself on its own body; to use the happy term invented by Havelock Ellis, we will say that it is autoerotic.[11]
It is, moreover, clear that the action of the thumbsucking child is determined by the fact that it seeks a pleasure which has already been experienced and is now remembered. Through the rhythmic sucking on a portion of the skin or mucous membrane it finds the gratification in the simplest way. It is also easy to conjecture on what occasions the child first experienced this pleasure which it now strives to renew. The first and most important activity in the child's life, the sucking from the mother's breast (or its substitute), must have acquainted it with this pleasure. We would say that the child's lips behaved like an _erogenous zone_, and that the excitement through the warm stream of milk was really the cause of the pleasurable sensation. To be sure, the gratification of the erogenous zone was at first united with the gratification of taking nourishment. He who sees a satiated child sink back from the mother's breast, and fall asleep with reddened cheeks and blissful smile, will have to admit that this picture remains as typical of the expression of sexual gratification in later life. But the desire for repetition of the sexual gratification is separated from the desire for taking nourishment; a separation which becomes unavoidable with the appearance of the teeth when the nourishment is no longer sucked in but chewed. The child does not make use of a strange object for sucking but prefers its own skin because it is more convenient, because it thus makes itself independent of the outer world which it cannot yet control, and because in this way it creates for itself, as it were, a second, even if an inferior, erogenous zone. The inferiority of this second region urges it later to seek the same parts, the lips of another person. ("It is a pity that I cannot kiss myself," might be attributed to it.)
Not all children suck their thumbs. It may be assumed that it is found only in children in whom the erogenous significance of the lip-zone is constitutionally reënforced. Children in whom this is retained are habitual kissers as adults and show a tendency to perverse kissing, or as men they have a marked desire for drinking and smoking. But if repression comes into play they experience disgust for eating and evince hysterical vomiting. By virtue of the community of the lip-zone the repression encroaches upon the impulse of nourishment. Many of my female patients showing disturbances in eating, such as hysterical globus, choking sensations, and vomiting, have been energetic thumbsuckers during infancy. In the thumbsucking or pleasure-sucking we have already been able to observe the three essential characters of an infantile sexual manifestation. The latter has its origin in conjunction with a bodily function which is very important for life, it does not yet know any sexual object, it is _autoerotic_ and its sexual aim is under the control of an _erogenous zone_. Let us assume for the present that these characters also hold true for most of the other activities of the infantile sexual impulse.
