In a family, in happens frequently, that with a newborn has a fraternal rivalry emerges, but from a other side a kids competition is to obtain first the attention or the love of their mother (or of any other members in a given environment). This rivalry is being expressed through either positive behavior for example “a higher merit”, or negative behavior like envy, failure and breakdown (especially in the case of enuresis and encopresis). The jealous word expresses insuffiently the fraternal feeling, because they are very complex one. The child has unpleasant feelings when he need to fight for his advantages or when he is in a rivality situation, when he has reserves to be exclusive one. He could not have exclusive affection feelings for his brother when he is in a rivality situation with him, and feels ashamed for that. In reality this feelings are not bad at all, but are a secondary interpreted.
