The Duchess of Cambridge has broken from royal tradition by taking the official photos of the Prince George , Princess Charlotte and Prince Louis herself, rather than bringing in a professional.
Kate is a keen amateur photographer and has shown off her skills with adorable snaps of the Cambridge kids over the last few years.
She's been widely praised for the photos and the royal tots always look happy and relaxed in the pictures she shares with fans.
But eagled-eyed fans have spotted one thing they all have in common, and it's very, very cute.
In almost all of the pictures she's taken at least one of the children is wearing some sort of hand-me-down item of clothing.
In many of the photos of Charlotte, Kate has dressed her brother's old shoes or jumpers.
In the first official snaps of Prince Louis, the princess is wearing a blue jumper George wore for the Queen's 90th birthday photos.
Her little brother is wearing a white jumper that she wore for her official photos a few years previously.
In the most recent official photos of Louis, he's wearing one of George's jumpers that is several years old.
While Charlotte's outfits for her first birthday photoshoot are new, the shoes are the same ones we've seen George in on several occasions, including during Royal Tours.
It's hardly surprising that Kate often recycles her kids for important moments, as it's something she does herself.
Since stepping into the public spotlight the Duchess has been known for re-wearing a lot of her fashion pieces - something many other royals don't do.
Photographers have been largely impressed by her skills behind the camera, including the Mirror's photographer Ian Vogler.
He said: He said: “It’s always hard to get a nice picture of very young children. I know from my own experiences. But the Duchess of Cambridge has done a really good job with the picture of Princess Charlotte and Prince Louis.
“It’s a really charming image of a big sister proud of her new sibling.
“Both pictures are nicely lit with natural daylight the best way to photograph children. The picture of Prince Louis on his own is more formal looking but at the same time it’s very good.
“Just getting such a young baby to keep his eyes open is an achievement.”
