John Kahan has a poignant photo in his office at Microsoft Corp, where he oversees customer data and analytics. The image shows Kahan, his wife and three daughters celebrating the birth of a boy, his reddish-blond hair hidden by a hat. 

A few hours after the photo was taken, Kahan received a phone call he still has trouble recounting without choking up: his baby son, Aaron, had stopped breathing. A few days later he died with no explanation, a victim of Sudden Infant Death Syndrome.
