While some would assume that being a royal, regardless of age, is associated with poise and perfection, Louis proves in these new photos that there’s always time for some fun in the grass — even if that means getting dirty and being caught in the action!

As he was captured playing outside, Louis’ red sweater and navy pants became covered in grass. Still, that didn’t stop Kate and William’s youngest child from enjoying the moment as he showed off his giant smile and blonde locks, which were combed to the side.

Louis’ cheerful demeanor in the images is typical of the little royal, according to a source close to the family.

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