Child: biological, adopted or foster child,
a stepchild, a legal ward or a child of a person standing in loco
parentis, who is either under age 18 or age 18 or older and incapable
of self-care because of a mental or physical disability. Persons who
are in loco parentis include those with day-to-day responsibilities
to care for and financially support a child or, in the case of an
employee, who had such responsibility for the employee when the employee
was a child. A biological or legal relationship is not necessary.
