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.
