Q. 1. What is a "Godchild?"
A. 1. A Godchild is a child that is about to be admitted into the Catholic Church through the Sacrament of Baptism.
For the Baptismal Ceremony, the Godchild needs one or two Godparents, called Sponsors, who promise to assist the parent in raising the child in the Catholic faith. If there are two Godparents, it must be a male and a female.
A female Godchild is called a Goddaughter and a male Godchild is called a Godson.
So when a woman (a Godmother) refers to her Godchild (Goddaughter or Godson), she is referring to the child for which she made a commitments to be raised in the Catholic faith on behalf of the child who was too young (ex: a baby) to make such a commitment.
