(CBS) Beth Twitty has received some much needed help this week in Aruba. Not another search team, but from one of the few people who can identify with her tireless search for a lost child: another mother. Her own.

Twitty's daughter, Alabama teen Natalee Holloway, has been missing almost three months after vanishing at the end of a graduation trip to the island.

"One thing is we're going to have to have an answer. We're gonna have to," Twitty says. "There's no way that I can just let it go with no answer. I've got to have something. I'm gonna have to."

Twitty's mother, Ann Reynolds, lives in Arkansas and, for the past few months, Twitty's televised public pleas were the only times Reynolds got to see her. Last week, Reynolds arrived in Aruba to be by her daughter's side.

They spoke with CBS News.

"It's been great having the support and for mom for being here," Twitty says.

Reynolds temporarily resumed her role as Twitty's caretaker.

"I just love her and just can't stand to see her suffer," Reynolds says.

Reynolds worries about things Twitty would like to, but just can't.

"Of course," says Reynolds, "I want everything to go, so she can go back home. Because she does have Matt back home, and that does sort of worry me. Matt's her son."
