Kate suffers acute morning sickness
December 4, 2012: The couple stunned millions around the world, including their families, with the baby bombshell hours earlier, while an anxious Prince William left hospital after his wife had been admitted suffering from acute morning sickness.
Barely eight weeks into her pregnancy, Kate was taken to the hospital just after lunch by her husband and immediately put on a drip to stop her becoming dehydrated.
The controversial phone prank incident
December 6, 2012: An Australian radio show was at the centre of a hoax call controversy involving Prince William and his pregnant wife Catherine. The Duchess was in hospital suffering from morning sickness when the Aussie DJ talked to Kate's nurse while impersonating the Queen.
The whole ordeal lead to the death of the nurse who took the phone call, finally resulting in the show being taken off air.
Kate gives birth to first child
July 23, 2013: "We could not be happier," William, the son of Charles and the late Princess Diana, said in a brief statement.
The Duchess of Cambridge, 31, spends ten hours in labour after she and William went to the private Lindo wing of London's St Mary's Hospital, Paddington, in central London at about dawn (local time). Catherine then gives birth to a healthy male heir weighing 8lbs 6oz at 4.24pm.
Royal baby's name revealed
July 25, 2013: Three days later, Britain's Prince William and his wife Kate named their baby boy George Alexander Louis, sticking firmly to royal tradition with a first name used by six previous monarchs.
George was the bookmakers' clear favourite for the third-in-line to the throne as it pays apparent tribute to Queen Elizabeth II's father King George VI, the infant's great-great-grandfather, who died in 1952.
