“Our dream girl” reads the caption over the little girl with auburn hair, perched in her father’s arms, back to the camera. Princess Lilibet and her brother, Prince Archie, might once have been off-limits on the Duchess of Sussex’s social media feeds – but now, they are an integral part of brand Sussex.

Since Meghan reactivated her Instagram account last January, around a quarter of her posts either mention or feature her children, according to analysis from Sky News Australia – often in relation to or in proximity to products she is trying to shift, or speaking engagements she is to attend.

Last month, on Archie’s seventh birthday, Meghan posted a photo of her son – unusually, with his face visible – as a baby asleep on Prince Harry’s chest. This week, for Lilibet’s fifth birthday, she has shared two new images, with her face covered by her hair.

With the Duchess recently releasing a range of candles through her lifestyle company, As ever, starting at $64 (£48) with one collection costing $256 (£190), many are now expecting more artfully curated photos of the family to appear. In one post last year, an off-camera Lilibet had a speaking cameo in one of Meghan’s videos, describing As ever’s jam as “delicious”.
