It’s not unusual for twins to be born at Memorial Hospital and Manor’s Kirbo Women’s Center, but December seems to be a special month for twins. Not only were the Acosta twin girls and Overton twin boys born last week, two more sets of twins are also due before the year’s end. Juan and Olga Acosta are the parents of the twin girls, Andrea Rafaela and Natalia Alejandra. Levi and Lindsey Overton are the parents of the twin boys, Kale Thomas and Carter James.  Both sets of twins and their parents are from Bainbridge.
