Kate Middleton has ‘growing competition’ from Princess Charlotte in new Christmas card

She added: “William sports a smile of suppressed delight and pride at his family unit and he leans his head in towards Kate in a gesture that hints that he sees her as the rock of the group.”

Prince Louis, who is just two-years-old, appears to be the most care-free of the five.

In the latest photo, he appears to be enthusiastically laughing with his left hand in a fist.

The young Prince’s hair matches his older brother’s in style and shape.

Judi continued: “Louis is always the one who appears to be enjoying himself the most, while George adopts a pose we see a lot, sitting by his father, looking slightly more reserved than his other siblings.”
