This is probably not what they were bargaining for when planning their family...but it's pretty cool, in any case (especially since no fertility drugs were used).

EAU CLAIRE, Wis. - Identical twins are rare. Identical triplets even more rare. A Wisconsin couple now has both.

Matthew and Christine Rowe's family just grew by three identical baby boys. The Eau Claire couple had identical twin girls two years ago.

The Rowes say their doctor told them the births are extremely rare, perhaps one in 15 million. No fertility drugs were used.

The mother of five says other than sleep deprivation, the hardest part is telling the boys apart. She says they're keeping tracking of the boys with the help of a marker on their tiny feet.
