Chantal was a very active, rebellious child. She tended to argue with her mother & fought with her younger brothers. She wished to have a sisters. During teaching she wanted Jo to disappear. After teaching, she started to make progress with her behavior.
Sometime after "Supernanny" Chantal's wish to have a sister came true. Her sisters were a set of twins.
She was 7 at the period of her debut on Supernanny, and is now 18 as of 2016.
