The purpose of this paper is twofold: (1) to describe an adaptation of the Schaefer Circumplex Model to age-related parenting theory and techniques, and (2) to illustrate its application in relation to the emerging numbers of single-by-choice mothers. The method described superimposes both a child's and a parent's cognitive and psychosocial timelines onto the Schaefer Circumplex Model, assigning appropriate parenting styles and techniques to the corresponding cognitive and psychosocial stages of the child. The application of the developmental parenting process model to the mentoring process practiced by a support group for mothers who were single by choice illustrates the model's usefulness and highlights its appropriateness for this particular parenting population.
