Royal fans were thrilled to see members of the family out in full force on Christmas Day as they headed to a festive church service in Sandringham, Norfolk.
King Charles led his relatives on the walk to St Mary Magdalene for the first time following the death of his mother, the Queen back in September, and the group notably included some of the youngest royals, like Prince George, Princess Charlotte, and Prince Louis.
There were some touching moments between the children as they walked, but one of the 'sweetest and most poignant' took place when George put a hand out on his younger brother's back, according to body language expert Judi James.
The expert claims this signal between the two siblings was like a 'mirror image' of the relationship Prince William and Prince Harry used to share when they were of a similar age, before they grew up and seemingly grew apart.
Judi explained: "One of the sweetest and most poignant body language signals was the sight of George using touch, chat, and bending rituals to signal he is now in the role of protector and 'keeping-an-eye-on' monitor for his younger brother Louis.
"As the family reached the church William put a hand out to touch George's back and leaned towards his elder son but George was already using those same rituals towards his small and rather playful brother.
"The gesture looked spontaneous, as though this is a role he is taking on a lot and, after the footage of a young William and Harry growing up together that was shown in Harry’s Netflix show, it looked like a poignant mirror-image of how their sibling relationship shaped up before they grew up and fell apart.
"William was shown in caring mode for Harry back then, just as George is now with Louis.
"The links can't have been lost on William."
The expert went on to share how the Prince and Princess of Wales shared several 'intentional gestures' with their children during the Christmas walk to show how they are now becoming more 'hands-off' parents.
She added: "William and Kate showed off their children with the usual signals of pride and it was clear they are now becoming 'hands-off' parents as their children grow in confidence.
"Charlotte was pulling ahead as they walked towards the church and George has gone from being the rather shy-looking boy holding his father's hand to the older brother keeping an eye on and showing nurturing and directional signals towards the four-year-old Louis."
