This paper explains that the birth-order effects theory assumes that the order in which a person is born into his or her
family can have an everlasting impact on the way he or she interacts in society; there are four general categories: First-born,
middle-born, last-born and the only child. The author points out that there are several factors to consider when examining birth order and its effects; spacing,
gender, sequence of gender, genes and sibling deaths are a few. The paper relates that stereotypically (1) a first-born child is described as reliable, hardworking and a natural leader; (2) the middle-born child is the mediator, independent and jealous; (3) the youngest child is manipulative, charming and a people-person and (4) the only child is selfish, high expectations of oneself and unrelenting-a "super first born".
