Sunday is Mother's Day, one of the year's high points of gratitude. So as we honor the mothers among us (and those no longer among us), there's no better time to tap into that gratitude and draw on the qualities that make mothers such a force for good -- their generosity, their nurturing, their unconditional love. We're doing that with two initiatives, the Global Mom Relay and Mom+Social, both harnessing the power of motherhood and social media to improve the lives of mothers and children around the world. In the course of the Relay, we've heard a range of voices, and each time you share a post, a $5 donation is made by Johnson & Johnson and the Bill & Melinda Gates Foundation. And there's still time to join.
