character and that of a naughty child is strikingly evident. A compulsion neurosis, on the other hand, corresponds to a super-morality, imposed upon the primary character that is again asserting itself, as an increased check. Many persons, then, who love their brothers and sisters, and who would feel bereaved by their decease, have evil wishes towards them from earlier times in their unconscious wishes, which are capable of being realised in the dream. It is particularly interesting to observe little children up to three years old in their attitude towards their brothers and sisters. So far the child has been the only one; he is now informed that the stork has brought a new child. The younger surveys the arrival, and then expresses his opinion decidedly: “The stork had better take it back again.”[BY] I subscribe in all seriousness to the opinion that the child knows enough to calculate the disadvantage it has to expect on account of the new-comer. I know in the case of a lady of my acquaintance who agrees very well with a sister four years younger than herself, that she responded to the news of her younger sister’s arrival with the following words: “But I shan’t give her my red cap, anyway.” If the child comes to this realisation only at a later time, its enmity will be aroused at that point. I know of a case where a girl, not yet three years old, tried to strangle a suckling in the cradle, because its continued presence, she suspected, boded her no good. Children are capable of envy at this time of life in all its intensity and distinctness. Again, perhaps, the little brother or sister has really soon disappeared; the child has again drawn the entire affection of the household to itself, and then a new child is sent by the stork; is it then unnatural for the favourite to wish that the new competitor may have the same fate as the earlier one, in order that he may be treated as well as he was before during the interval? Of course this attitude of the child towards the younger infant is under normal circumstances a simple function of the difference of age. After a certain time the maternal instincts of the girl will be excited towards the helpless new-born child. Feelings of enmity towards brothers and sisters must occur far more frequently during the age of childhood than is noted by the dull observation of adults.
