One of Geoffrey's most popular programs in the Harlem Children's Zone is actually geared toward adults. Every Saturday morning, parents file into classrooms for Baby College. During these free parenting classes, new moms and dads learn about everything from health to early childhood development.

Geoffrey says the parents also learn how to discipline their children without spanking or hitting. "We have so many of our children who end up in foster care because their parents lost control," he says. "We figured out 30 years ago how you can raise a child without hitting, and no one's ever told these parents. They're skeptical at first, but as they begin to see it work, they say, 'You know what? Maybe you've got something there.'"

These lessons have helped transform the lives of hundreds of parents in Harlem. Darlene, a mom enrolled in Baby College, says instructors helped her develop positive parenting skills. "I would say to myself, 'How can you not hit? How can you not yell at him?'" she says. "They told us, 'Take your time and read instead of always yelling.' I started reading bedtime stories to him. Now, he reads to me. What I know is that in the future, my son's going to be somebody."
