Prince Louis appeared to tug at his mum the Princess of Wales' hand as he grew restless meeting the crowds who had gathered at Sandringham to see the royals on Christmas Day.
Prince William and Kate proudly walked with their children Prince George, Princess Charlotte and Louis as members of the Firm made their way to their annual festive church service.
George, nine, and seven-year-old Charlotte have carried out the walk before, but this year was the first year that four-year-old Louis, who donned shorts and long socks, joined them.
After the service, the royals stopped to chat to some of the wellwishers who had lined the route, with George, Charlotte and Louis all appearing to have been given gifts by the crowds.
But at one point as Kate held Louis' hand as she chatted, the cheeky wellwisher seemed eager to get back to Sandringham House and was seen adorably pulling at her arm to hurry her along.
Meanwhile, today also marked the first time that King Charles led the family to and from church - with him hosting Christmas at Sandringham for the first time this year since the death of his mother the Queen in September.
Charles led the way alongside Camilla in blue with William, Kate and their children following behind.
Among others that were spotted were Queen Consort Camilla, Zara and Mike Tindall, Edward and Sophie Wessex with Lady Louise Windsor and James, Viscount Severn as well as Princess Beatrice, her husband Edoardo Mapelli Mozzi and his son Wolfie.
A surprise appearance at the church was by disgraced Prince Andrew, who was seen alongside his youngest daughter Princess Eugenie and her husband Jack Brooksbank.
Christmas at Sandringham follows a break, when, due to the Covid pandemic, the late Queen spent the festive period at Windsor Castle two years in a row – the first with the Duke of Edinburgh, separated from her wider family in lockdown.
After the morning trip to St Mary Magdalene Church and the greeting of well-wishers, the family are expected to tuck into a lunch of turkey and all the trimmings.
Afterwards traditionally members of the royal family sit down to watch the Queen's televised address when it airs after lunch at 3pm on December 25.
This year, they will watch King Charles' first ever Christmas address, where he is expected to to pay tribute to the late Queen.
An image of Charles, taken during the recording of his inaugural festive address, has already been released ahead of the broadcast being screened later today.
The annual festive message was recorded on December 13 at St George’s Chapel, Windsor Castle, a religious building which has a strong association with the late Queen and where she is buried alongside Prince Philip.
It was filmed in the quire of St George’s Chapel, where the royal family sat during the Queen’s committal service, and during the broadcast the choir of St George’s Chapel, Windsor performs the National Anthem and sings a carol.
The monarch is pictured standing while delivering his address. Although in recent years the Queen recorded her Christmas broadcast sat at a desk, she had also stood in decades past.
