Meghan Markle and Prince Harry’s son is six!

The Duke and Duchess of Sussex celebrated Prince Archie’s birthday on Tuesday, which the As Ever founder marked with an Instagram post.

“Our son. Our sun. Happy 6th birthday to Archie!” Meghan wrote, alongside a photo of Archie turning to look at the sun.

“Thank you for all of the love, prayers, and warm wishes for our sweet boy. He’s six!” the duchess added, before asking a question all parents can relate to: “Where did the time go?”

Before signing off, Meghan thanked everyone who attended Archie’s birthday celebration.

“For all of you who came to celebrate with us at his party last weekend, thank you for making his birthday so incredibly special,” she added alongside a red heart emoji.
