The claimant is exercising parental control and responsibility if the claimant supervises
the child's activities, participates in the important decisions about the child's
physical and mental needs, and measurably controls the child's upbringing and development.
The fact that the claimant has not lost the legal right to custody of the child, furnishes
support for the child, and retains the right to exercise supervision is not sufficient.
There must be an actual exercise of parental control and responsibility, i.e., the
claimant must influence the training and development of the child in material respects.
