Less than seven hours later, Middleton and Prince William emerged from the hospital with their son, heading back to Kensington Palace. To many people, this seemed like a very quick turnaround when bringing a newborn home. In the U.K., new moms average a day and a half in the hospital before heading home, according to The Guardian.
