St. Clair Shores — A couple who have two older children are adjusting to life after becoming parents to identical triplets — a multiple birth a doctor calls rare.

The Whiteleys are celebrating the one-month birthdays Wednesday for Alexander, Nicholas and Timothy.

Lauren Whiteley, who wasn't taking fertility treatments, says it "was the shock of a lifetime" when an ultrasound revealed three fetuses.

She and her husband, Michael, say triplets don't run in their families. Their older sons are 4 and 2.

Neonatologist Dr. Savitri Kumar at Henry Ford Hospital in Detroit, where the triplets were born Jan. 25, says data on triplet births by natural conception is "very variable from one in 60,000 to one in 2 million." Kumar says one-in-a-million is "the most commonly quoted."
