Prince Louis helping big sister Princess Charlotte sends royal fans wild Prince Louis' priceless reaction to helping his big sister Princess Charlotte toast marshmallows thrilled royal fans last year.
After Louis' first bite, he turns around and rolls his head backwards in delight, before falling onto Charlotte, who looked like she needed a break!.
The lively six-year-old was snapped tucking into the treat as the Wales family took part in the Big Help Out at 3rd Upton Scouts Hut in Slough as they gave the bid to renovate and improve the building a boost.
Footage shows Kate and a scout member helping keen Louis prepare a marshmallow biscuit sandwich, which he really could not wait to devour.
Little Louis was overwhelmed with excitement as he enjoyed a messy s'more around the fire as a reward for his hard work while volunteering.
