Lycee grad here. I rode the bus from the age of 4 on (and on, and on, and on - spent 15 years there). The bus driver always made the little ones sit up front where he could watch us. When I was in high school, my dad's coworker lived near us and her much younger daughter rode the same bus, so she would always come sit by me. If you get to know the other Lycee families near you, I bet you could find a similar "bus buddy."
There were also many carpooling families. Well, and the occasional ambassador's kids being dropped off by chauffeur
