The Mason Family is an episode of Supernanny. In this episode, Jo heads to Sanford where for the first time ever, it's the children calling for her help. Anna (18) and Trent Mason (16) have become third parents to their younger siblings, Grace (9) and Robert (7 1/2) because parents Frank (51) and Cheryl (48) would rather work than be with their own children. This has caused Grace and Robert to both misbehave and Anna and Trent a lot of emotional and physical draining. Can Jo get Frank and Cheryl to step up? Or will she be sent out the door?
