Ann Sullivan, 74, of Brighton, N.Y., has never had children of her own, but has always loved being around children. During the week, she babysits two-year-old Cava Webb, while her mother and father are at work. Ann feels a strong connection to Cava. "There's just something about her," she says. As she grows older, Ann worries that health problems will affect her being able to continue babysitting Cava.
