Princess Lilibet turned four on 4 June, and her mother Meghan shared the images to social media to celebrate.
“Four years ago today she came into our lives – and each day is brighter and better because of it,” Meghan said.
Meghan also shared photos of Lilibet with Prince Harry – one of the Princess as a newborn, and a recent image of father and daughter running together.
The social media tributes continued, with Meghan sharing a video from the day Lilibet was born.
Meghan and Harry are seen dancing in a hospital room, in a last-ditch effort to bring on labour.
“Both of our children were a week past their due dates…” Meghan wrote, “so when spicy food, all that walking, and acupuncture didn’t work – there was only one thing left to do!”
It comes after the Duchess shared a video of herself beekeeping alongside Lilibet, saying she was “harvesting honey with my little honey”.
