Jo visits the Naszkiewicz Family in Royal Palm Beach, Florida where Jen (35) and Roy (40) are having a hard time with their four crazy kids: 12-year-old Jordan, 9-year-old Tanner, 4-year-old Zachary, and 2-year-old Kaia.
Jordan and Tanner fight aggressively with each other like they have a hatred of each other. Kaia throws her fits like any other 2 year old. These 3 girls are not the biggest problem though.
Meanwhile, only boy Zachary is a dominant and stubborn child that rules roost. He would throw violent temper tantrums and gets jealous of his sisters getting more attention than him, so he acts out. He would lash out at Kaia and his mom.
Jen doesn't discipline the kids, constantly gives into Zachary's tantrums and pacifies him to make him stop. The father, Roy is the exact opposite, he often loses his cool with the kids. However, thanks to Zachary's control, Jen and Roy are not on the same page when it comes to discipline and their relationship is starting to fall apart.
On the Submission Reel, Jen tearfully tells Jo that Supernanny is their last shot or they'll end up getting divorced. Can Jo teach them how to properly tame Zachary's tantrums and repair their relationship?
This is one of the times where the kid who throws tantrums greets Jo at the door.
