Just when we thought that Prince Louis couldn't get any cuter [1], the Duke and Duchess of Cambridge decided to share another adorable photograph of the little royal. In the precious snap, which was taken alongside Louis's official christening portraits [2], a radiant Kate can be seen cradling her laughing baby boy in her arms in the garden of Clarence House. And while we might never know what prompted such a sweet reaction from the 2-month-old, we have a feeling that cheeky Prince George and Princess Charlotte [3] might be the reason behind those giggles.

Prince Louis's christening [4] was the first time we got to get a glimpse at the tiny royal since his official photos with sister Charlotte [5] in May. As the precious christening portraits were released over the weekend, Kate and William enjoyed some couple time [6] at Wimbledon to watch the men's singles final, and the Duchess of Cambridge also spent some quality time with Meghan Markle [7] when the duo checked out Serena William's match.
