There are so many firsts in a child's life, but few can compare to this one. It's almost too much for Mavis Malone: She can hear for the very first time. The 2-year-old was born a genetic defect, leaving her with profound hearing loss. Hopes were high a four-hour surgery would change that. Doctors put cochlear implants in both ears, the devices delivering sound directly to the auditory nerve. Now, without her mom signing, Mavis understands and a trip to the park with her older brothers is a whole new world.
