Author Lauren Charpio says today's grandparents no longer want to be called Grandma and Grandpa. These days, new grandparents, many of whom are baby boomers, are "searching for a name that makes them feel cool and hip, active and diverse, all while taking on the coveted role of grandparent," she argues. Charpio has written You Can Call Me Hoppa! The Grandparent's Guide to Choosing a Name That Fits. It's available on Amazon.com or CallMeHoppa.com.
