Jaycee Lee Dugard in an undated photo
The call to Joan Curry came just after midnight. It was her daughter, Terry Probyn, and Curry could barely believe what she was hearing.
"Jaycee's alive! Jaycee's alive!" Curry yelled, waking up her husband.
Now, a week later, the task of rebuilding granddaughter Jaycee Dugard's life after she was abducted for nearly two decades is well under way – and Jaycee's mother Terry is not letting her out of her sight.
"She's like a little mother hen right now. She's got them all gathered around her and that's the way it's going to stay for a while," Curry tells PEOPLE exclusively.
Curry adds, "Terry's in the clouds. They're doing very well. She's very encouraged, very encouraged, very optimistic about the outcome of all of this."
Jaycee, who had missing since 1991 when she was abducted as an 11-year-old just blocks from her South Lake Tahoe home, was found Aug. 26 by police and reunited with her family the next day.
"We were elated. I don't think it had sunk in. We were so elated," she says. "There's not a word for how we felt. We laughed. We cried. We hugged each other. All the things that you do when something like this happens."
Phillip Garrido, 58, and his wife Nancy Garrido, 54, of Antioch, Calif., were arrested for the abduction. Phillip also allegedly fathered two girls with Jaycee. The girls, who thought Jaycee was their older sister, have just been told she's their mother.
