A lot has happened for the Royal family in the last five years.
But if you cast your mind back to 2014, you might remember that the Cambridges embarked on a tour of Australia and New Zealand.
Arguably the highlight of their tour was Prince George , then a chubby-cheeked nine-month-old who won hearts Down Under.
So much so, he was even dubbed the Republican Slayer, which is a pretty hefty nickname for a baby.
Why Meghan Markle's due date for royal baby could be sooner than we think
It was on the New Zealand leg that photographer Simon Woolf took a candid shot of the Duchess of Cambridge and the young prince.
Taken at a group play date in Wellington, it showed an incredibly tender moment between mother and son.
Kate certainly seemed to like it too.

Woolf later revealed that the Duchess gave him some glowing feedback saying, "She [the Duchess] said it was just lovely and that it was her favorite photo of the tour," Vanity Fair reports.
He added that he delivered her a black-and-white version of the photograph, when the New Zealand part of the tour was over.
The Duchess of Cambridge is famously a keen photographer, and loves to snap her own growing brood.
No doubt she has a whole trove of photos at home, but it's lovely that the world got to witness this moment.
