Hi all. I have a coworker whose 3 year old is obsessed with motorcycles. Apparently he dresses up like one to go to school and tells everyone that he is a "Motorcycle dude". She's buying him some battery powered ducatti (?) for xmas, but says he really wants a helmet (lucky kid right?). Does anyone have any suggestions? It would have to fit him and be functional, but I doubt in needs to be DOT.
