Firstborn

Eldest child

A firstborn is the first child born to in the birth order of a couple through childbirth. Historically, the role of the firstborn child has been socially significant, particularly for a firstborn son in patriarchal societies. In law, many systems have incorporated the concept of primogeniture, wherein the firstborn child inherits their parent's property. The firstborn in Judaism, the bechor, is also accorded a special position.
