As mothers and daughters age, their relationship shifts and changes in complex and often demanding ways. Dr. Terri talks with Sandra Butler, co-author of the book, "It Never Ends." In the book, women speak openly about the satisfactions and sorrows of mothering middle-aged daughters and discuss the issues that continue to surface, the ongoing effects of the past on the present, and the varied and often invisible ways they continue mothering. Sandra Butler and her co-author Nan Fink Gefen draw from their own experiences as mothers, as well as interviews with over 75 older moms to gather insight and information.
