"Your service to the causes you care so deeply for inspires me every day," she wrote of Harry, using images of him as a child, with his mother Princess Diana, with his brother Prince William, at their wedding, and in military gear. "You are the best husband and most amazing dad to our son. We love you ❤️Happiest birthday!"
One black-and-white image of Meghan, Harry and Archie by Chris Allerton made its debut in the post. In the shot, Harry kneels before a seated Meghan, cooing into the face of little Archie — nestled snugly on Meghan's lap — on the day he was christened.
Archie, 4 months old, is rarely seen on the official account.
This marks Harry's first birthday as a dad, and Meghan obviously did not want to let it go by without this extra-special gift.
