The Duke of Duchess of Cambridge introduced their lovely baby son to the world on Monday, just hours after Kate gave birth after being admitted to the Lindo Wing in the early hours of the morning.
Cradled in the arms of his mother, the royal baby was swaddled tightly in a crocheted wrap and wore a matching beanie for his first public appearance.
Kate gave birth to the 8lb 7oz new prince - who has yet to be named - at 11.01am on St George's Day.
In a clip, the Duke can be seen holding his kids by the hand.
With the palace announcing Kate and her son were "both doing well", and that the Queen, Prince Philip, Prince Charles, Camilla, Prince Harry and members of both families were "delighted with the news", the waiting game then recommenced as the world anticipated the hospital doors swinging open for the first glimpse of the newest royal.
The Duck left the hospital, telling crowds, "I'll be back in a minute", before returning with George and Charlotte to introduce them to their new brother. William is now second in line to the throne, behind his father, Prince Charles, who will take the reins as monarch when Queen Elizabeth II dies.
According to a royal photographer, an ideal photo when Middleton leaves the hospital after delivering the new baby would be capturing the family of five.
The Duke and Duchess reportedly used luxury design company Dragons of Walton Street, Knightsbridge, to create their children's nursery - the same company who designed William and Harry's childhood nursery.
