No one can deny that the Duke and Duchess of Sussex, Prince Harry and Meghan Markle, have one stinkin’ adorable family. After getting married in May 2018 and having their first child in May 2019, we can’t help but swoon at all the obvious love between the whole royal clan.

So what better way to celebrate Harry’s 35th birthday than by showcasing the adoration with a precious new photo from the baby Archie archives?

At just four months old, we don’t get a ton of face-time with Archie Harrison Mountbatten-Windsor, Harry and Meghan’s son. So when we do, we can’t help but smile ear to ear!

The sweet, never-before-seen photo, was taken at Archie’s christening in July, and posted to the two’s shared Instagram account @sussexroyal. The caption read:

“Your service to the causes you care so deeply for inspires me every day,” she said. “You are the best husband and most amazing dad to our son. We love you ❤️ Happiest birthday!”

The photo was just the last photo of an entire photo collage that chronicled Harry throughout the years, starting with a photo of him being held by his late mother, Princess Diana, probably just as young as Archie is now.

The rest of the photos in the collage go through his childhood, to his philanthropic efforts, and eventually to his wedding and parenthood. It’s one of the sweetest things we’ve ever seen!

Harry’s birthday was September 15, and we’re sure it was a day to remember. But not to worry, Prince Harry returned the favor on his wife’s birthday as well. To hear how he paid her tribute, check out the video below!

Could this couple be any sweeter? How cute was the collage Meghan made for Harry’s birthday? Any guesses for what the two did afterwards to celebrate the big 35?
