Sitting beside a neatly made crib, 88-year-old Vivian Guzofsky holds up a baby doll dressed in puppy dog pajamas.
"Hello gorgeous," she says, laughing. "You're so cute."
Guzofsky, who has Alzheimer's disease, lives on a secure memory floor at a home for seniors in Beverly Hills, Calif. She visits the dolls in the home's pretend nursery nearly every day. Sometimes Guzofsky changes their clothes or lays them down for a nap. One morning in August, she sings to them: "You are my sunshine, my only sunshine. You make me happy when skies are gray."
