Dr. William Gilbert, director of Sutter Women's Services, says the odds of producing identical triplets without fertility drugs range from 1-in-1-million to 1-in-100-million.

He said the rarity makes it difficult to more accurately calculate the frequency of such births.

Abby weighed 3 pounds, 2 ounces; Brin 3 pounds, 11 ounces; and Laurel 4 pounds.

The triplets are still in the hospital until they can maintain body temperature and eat properly.
