Prince George is pictured in the arms of the Duchess of Cambridge and surrounded by his immediate family in an official christening photograph that's been released.
The royal baby was baptised on Wednesday and his public appearance gave the world only its second glimpse of the future king.
George appeared happy and content throughout the day and his father William even joked just before the ceremony began that his son was the "quietest" he had been.
Later that evening the Queen described the baptism, carried out by the Archbishop of Canterbury, the Most Rev Justin Welby, as "very nice" when she appeared at a reception.
And Kate on Saturday night said George was "such a good boy" throughout the ceremony.

The duke and duchess chose celebrity portrait photographer Jason Bell to take the official pictures to mark the christening at the Chapel Royal at St James's Palace.
In the image that has been released Kate is shown seated on a sofa cradling her three-month-old son, with the Queen sitting on her right and William on her left, both pictured with their hands in their lap.
Baby George is wearing a replica of the intricate lace and satin christening gown made for Queen Victoria's eldest daughter, Victoria, the Princess Royal, in 1841.
Standing behind the sofa are the infant's immediate family - the royals and the Middletons.
George's seven godparents are not in the official pictures.
The picture was taken immediately after the christening service in the morning room of Clarence House the official London home of Charles and Camilla.
It is an historic image as it shows the Queen with three future monarchs - Charles, William and George.
The photograph has similarities with a picture taken in July 1894 during the christening of the future Edward VIII, showing the royal baby with his father, later George V, grandfather, the future Edward VII, and great grandmother, Queen Victoria.
Bell is renowned for his images of Hollywood stars and rock and pop legends like Sir Paul McCartney, actress Scarlett Johansson and former England footballer David Beckham.
