Royal fans will be looking forward to possibly seeing the Duke and Duchess of Cambridge take all three of their children to church on Christmas morning for the first time.
In 2019, Prince George and Princess Charlotte made their Sandringham public debut when they met well-wishers after the annual religious service at St Mary Magdalene.
Holding their proud parents' hands, the two adorable children smiled and waved to dedicated fans who waited for hours to see them - and it's hoped Prince Louis might join them this year.
During their appearance two years ago, Kate colour-coordinated the family's outfits, and they all looked very smart in dark green.


And while fans around the world loved their style, it turns out that Kate really regretted her outfit choice for the day, and even told one well-wisher she "really shouldn't have worn it".
Kate looked stunning in a heavy grey Catherine Walker coat, with a green hat, bag and heels.
But during a quick chat with 19-year-old fan Rachel Anvil, she admitted it was the wrong choice for the unseasonably warm weather.

Rachel's mother told Metro: "Kate was talking to my daughter about clothes and how she was feeling too hot, she said 'I really shouldn’t have worn this'.
"I’m there talking to Charlotte about dolls and my daughter’s talking about fashion with Kate.
"It wasn’t fake it was a genuine discussion, it was about a minute but it was tailored to my daughter, it was like speaking to a friend. They are totally different with the public."

Meanwhile, it has been reported that the Queen will be holding her usual family Christmas gathering at Sandringham this year and may make a public appearance for the first time since early autumn.
The monarch and late husband Prince Philip spent last Christmas alone as they shielded at Windsor Castle and it turned out to be their final festive season together, as the duke died aged 99 in April.
But it appears the Covid pandemic will not force the Queen, 95, to cancel her usual family gathering for the second year in a row.
According to reports, she is planning to host her family at her Norfolk estate and may even appear in public for the first time in months.
The monarch has been resting on doctors’ orders and only carrying out light duties such as audiences since spending a night in hospital for preliminary tests on October 20, and later spraining her back.
She is also preparing to film her Christmas Day message to the nation.
