The royal family reunited for the annual Christmas Day church service in Sandringham.
The Prince and Princess of Wales were once again joined by their three children, Prince George, ten, Princess Charlotte, eight, and Prince Louis, five.
After attending the service at St Mary Magdalene, cameras picked up a rather sweet moment between Kate, 41, and her youngest child, Louis.
As the King and Queen emerge from the church with the Waleses in tow, the Princess, dressed in a blue Alexander McQueen coat, can be seen chatting to her young son.
Kate can be seen gently guiding Louis towards the exit, holding his hand briefly before sweetly stroking his hair.
Watch the mother-son moment in the clip below…
Louis, who is in Year One at Lambrook school in Berkshire, has joined his parents and older siblings at a number of major royal events this year, including King Charles's coronation, Trooping the Colour, his mother's Christmas carol concert and his first ever public engagement with the Scouts in May.
As the Waleses walked to church, they were also joined by Mike and Zara Tindall's eldest child, Mia, nine, who was seen holding Louis' hand.
