There is a way that one carries themselves and expresses their personality that gives away crucial facts about their birth order. For many, being the first born automatically qualifies them into the role of being the deputy parent, while the middle child might often be the neglected one and the last-born child is often notoriously perceived as the carefree one of the bunch. On the other hand, being an only child, usually places you in the category of mature, and responsible. According to internationally known psychologist Dr Kevin Leman, the secret to sibling personality differences lies in their order of birth and how parents treat their children differently, based on whether they are the oldest, middle, youngest or only child.
