During a break time, George, Charlotte and Louis enjoyed some s’mores (toasted marshmallow and chocolate sandwiched between two graham crackers) and at this point of the day, Catherine revealed what her nickname for little Louis is.
“Pop that on the fire Lou-bugs,” Catherine said while teaching her youngest how to toast a marshmallow.

The Big Help Out actually marked Louis AKA Lou-bugs’ first official royal engagement.
But Louis and the rest of his family weren’t the only royals who took part in The Big Help Out.
The Duke and Duchess of Edinburgh took part in a puppy class at the Guide Dogs for the Blind Association Training Centre in Reading.
Sophie, the Duchess of Edinburgh, is actually Patron of the Guide Dogs for the Blind Association, so it makes sense that that was the volunteer program she and her husband Prince Edward helped out for The Big Day Out.
