Kensington Palace released the Prince Louis photos

To mark Louis’ first birthday, Kensington Palace unveiled the portraits taken by the Duchess of Cambridge earlier this month in the garden at their Norfolk home, Anmer Hall. The Palace included a statement with the pics, noting: “The Duke and Duchess of Cambridge are delighted to share three new photographs of Prince Louis ahead of his first birthday tomorrow. The photographs were taken earlier this month by The Duchess at their home in Norfolk.”

The chubby cheeked tot looks adorably happy and rosy, seen in one image wearing a red sweater with three shoulder buttons while he looks upward, exposing his two bottom teeth. In another pic, he wears a blue sweater with a dog image on the chest, staring into the camera with a more serious expression, his big eyes shining brightly. A third picture shows a more playful Louis moment, looking ready for some fun with his mouth expressively open in excitement.

A source told PEOPLE: “He really is the most cheerful, smiley little boy — he’s always so happy and content.”

Fans last caught a glimpse of Louis in the Cambridge family’s Christmas card portrait, where he posed along with his siblings and parents while sitting on Middleton’s lap.

Louis, who was born on April 23, 2018, looks a lot like dad, Prince William as well as his brother Prince George. Prince Louis is the fifth in line to the throne.

Louis’ latest milestone

While there are few details about what Louis has been up to now that he’s one, Middleton revealed last month during a visit to a children’s center that Prince Louis was getting ready to walk.

He was 11 months old at the time when she chatted with another parent about her youngest child, noting that he was active and enjoyed “bombing around” in a walker. She explained, “He just wants to pull himself up all the time. He’s got these little walkers and is bombing around on them.”

Prince Louis’ puppy sweater is winning over fans

Fans were quick to not only fall in love with Prince Louis’ cherub face, but also his cute puppy sweater, reminiscent of the whale sweater that Prince George wore for his third birthday photos in 2016.

The blue puppy sweater is available on the Trotters Childrenswear website for $47, in sizes 3-6 months through 24 months. The sweater’s description explains: “Our bestselling Puppy Jumper for baby boys now comes in a smart denim blue colour and features our sweet puppy intarsia design on the front. Made in a soft, warm cashmere mix it’s a must have for layering this spring. It also comes in a lovely pale pink to create the perfect matching outfits for little brothers and sisters.”
