In this connection it is instructive to compare the child's regard for his brothers and sisters with that which he has for his parents. The little child does not necessarily love his brothers and sisters, often, obviously, he does not love them at all. There is no doubt that in them he hates his rivals and it is known how frequently this attitude continues for many years until maturity, and even beyond, without interruption. Often enough this attitude is superseded by a more tender feeling, or rather let us say glossed over, but the hostile feeling appears regularly to have been the earlier. It is most noticeable in children of from two and one-half to four or five years of age, when a new little brother or sister arrives. The latter is usually received in a far from friendly manner. Expressions such as "I don't want him! Let the stork take him away again," are very usual. Subsequently every opportunity is made use of to disparage the new arrival, and even attempts to do him bodily harm, direct attacks, are not unheard of. If the difference in age is less, the child learns of the existence of the rival with intense psychic activity, and accommodates himself to the new situation. If the difference in age is greater, the new child may awaken certain sympathies as an interesting object, as a sort of living doll, and if the difference is eight years or more, motherly impulses, especially in the case of girls, may come into play. But to be truthful, when we disclose in a dream the wish for the death of a mother or sister we need seldom find it puzzling and may trace its origin easily to early childhood, often enough, also, to the propinquity of later years.
Probably no nurseries are free from mighty conflicts among the inhabitants. The motives are rivalry for the love of the parents, articles owned in common, the room itself. The hostile impulses are called forth by older as well as younger brothers and sisters. I believe it was Bernard Shaw who said: "If there is anyone who hates a young English lady more than does her mother, it is her elder sister." There is something about this saying, however, that arouses our antipathy. We can, at a pinch, understand hatred of brothers and sisters, and rivalry among them, but how may feelings of hatred force their way into the relationship between daughter and mother, parents and children?
