A 26-year-old Mexican woman gave birth to quintuplets in Tucson, Ariz., Sunday, four of whom reportedly were doing fine. The fifth was born dead.

Ana Rosa Ballesteros, of Nogales, Mexico, and her four surviving daughters reportedly were doing well. The babies were being cared for in the neonatal intensive care unit at University of Arizona Medical Center.Hospital spokeswoman Julieta Gonzalez said Ballesteros and her husband, Raul, a self-employed accountant, had known she was carrying five babies since her 17th week of pregnancy.

The babies ranged in weight from 2 pounds, 11/2 ounces, to 2 pounds, 5 1/2 ounces, Gonzalez said. The stillborn baby was a boy.
