Prince William's wife, Kate, cast aside British tradition when she picked the team that helped her deliver her baby on Monday.

Instead of turning to a midwife, an option favored by a majority of women in the U.K. as well as Queen Elizabeth II, the Duchess of Cambridge followed the U.S. practice of having doctors on hand for the birth of the boy who will be third in line to the British throne.

The royal birth was supervised by Marcus Setchell, who serves as the queen's gynecologist, and Guy Thorpe-Beeston, an obstetrician who practices at St. Mary's Hospital in Paddington, central London, where Kate's son, weighing 8 pounds, 6 ounces (3.8 kg) was born.
