Zachary is the worst one out of the four. He ruled the house with his constant tantrums and always wanted to get his own way. His older sisters would have to sneak around him when they wanted to go outside. He was also very jealous of Kaia whenever Jen gave her attention. During his time on Supernanny, he got sent to timeout thrice. Once for not listening to his mom when she told him not to spin a chair, another time for pushing his little sister Kaia and a third time for acting out on a family outing.
He was 4 years old in 2009, and will be 13 in 2018.
