Good deeds from a mother's love
After experiencing the loss of a child, Liam, a preemie who died at just five weeks, Mattie Mitchell has been the unseen hand behind an untold number of joyful surprises in Nashville, Tennessee. In the 10 years since she formed the nonprofit Liam Changed the World, Mitchell has performed hundreds of good deeds, each time reuniting in spirit with her son. Steve Hartman reports.
