The idea that the order of one’s birth in a family helps shape one’s personality; slightly more respected than phrenology in this day and age…

Although some analyses include categories such as twins, adopted children, “ghost children” (a child who died in infancy, but whose significance to the family is still felt by remaining siblings), the only girl in a family of boys and vice versa,1 basic birth order theory can be broken down into three categories; firstborn/ only child, second born/ middle child, and youngest. Of course, even those who put great faith in these theories acknowledge the influence of other factors in shaping children’s personalities: these include gender, the number of years between children in a family, the total number of children in a family, parental attitudes, and the social and economic position of the family.

People who adhere to this theory have extended it beyond the impact on the family of origin to include which birth orders should marry, and which are the best/ worst to work with.

Without further ado…

Oldest / only child

Only children

in addition to the above characteristics:
  • Conscientious, well-organized; list makers, reliable.
  • Are often the center of their parents’ attention; can be spoiled or over-protected.
  • May prefer adult company, even as children; may be loners and have trouble relating to or sharing with peers.

Second born/ middle child

Youngest child
