Three-year-old Matthew is spreading misery throughout the Pollard-Morris home. From dawn till dusk, he subjects parents Trisha and Daren and his three siblings to a soundtrack of whinging, whining, screaming and moaning. Everyone's sick of his behaviour. But when Supernanny Jo Frost arrives she offers a different diagnosis to the problem. She sees mum's tendency to mollycoddle Matthew with a diet of baby bottles and dummies as a key factor in the unhappy toddler's problem behaviour. Trisha lets Matthew use dummies through the day and he is pacified with a bottle several times a night. To make matters worse, sibling rivalry between eight-year-old Matt and James means there is never any peace in the house. Supernanny is clear. It's time to let these children grow up and take some responsiblity.
