birth order
Firstborn, middle, youngest
Birth order is the sequence in which siblings are born into a family—first, middle, last, or only child.
The term appears most often in discussions of personality development, where birth order is thought to shape traits: Studies on birth order suggest firstborns tend toward leadership roles.
The concept is popular in folk psychology, though its scientific support remains debated.
