How have the courts interpreted the word "children" in the context of the definition of a biological child?

These cases span over one hundred years, and they are not, as the majority would characterize them, merely "conflicting judicial interpretations." Opinion at 1442. Instead, they indicate that the word "children" is elastic, admitting more than biological children. This elasticity reflects social conditions today, when families are more fluid and the trend in the law has been to extend to stepchildren those rights and privileges accorded biological children. See Klossner v. San Juan County, 93 Wash.2d 42, 46, 605 P.2d 330, 332 (1980).
