Some parents think that one child is more comfortable than the other. According to them, since they do not encounter the unpleasantness of a single child competition, they reach an emotional balance in adult age, and a superior character gains safety. In reality, this is the opposite. Because the child who is the only child of the family has difficulty in adapting to various aspects of social life (school, marriage, etc.). The reason for this awakening is that there is no sibling competition at home. The presence of a brother at home is a kind of rehearsal of a number of situations the child will encounter in the future, as well as rehearsals made within the family walls/ismail.
