Grandparents have become an important source of subsidized noncustodial child care provision as states have developed child care subsidy programs for working families. Based on a sample of 140 grandparents providing care in one state subsidy program, this article examines grandparent characteristics, caregiving patterns, experiences with care provision, and training and resource needs in this emerging public service context. Our findings indicate that grandparents provide care largely for altruistic reasons. They offer vital care during nontraditional work hours and are more receptive to training provision than often is understood. Based on study findings, several strategies are presented for supporting subsidized grandparent caregivers. (author abstract)
