There are three children in the family but five year old Nathaniel is undoubtedly the ruler of the home. Ever since he was a baby he’s had diabetes and has learned how to use his illness to make his parents feel guilty and give him what he wants. He screams and throws tantrums all day, mostly for food and snacks, but his controlling behaviour even goes as far as dictating whether or not the TV is on, what his younger brother can and can’t do, and what he will wear and where he will go. Mum is so frustrated, she just shouts at him. Can Supernanny rein in this most demanding of boys?
