Twins have twins

Two twin sisters are seeing double - or make that quadruple - after delivering two sets of twin boys yesterday.

Twenty-one-year-olds Ashlee Spinks of Indianapolis and Andrea Springer of Conyers, Georgia, delivered their boys by Caesarean section about an hour apart at Northside Hospital.

The women were six months pregnant when they found out they were both going to have twin boys due on the same date - January 1, 2005.

The two couples said twins run in the families of all four parents.
