The Three Day Nanny is called to Northamptonshire, where the Scott family are at breaking point. Three-year-old Bobbie and two-year-old Freddie will pinch, punch, kick or bite anyone in sight and parents Chris and Becky seem unable to stop the onslaught. Kathryn Mewes witnesses some of the most extreme behaviour she's ever confronted and wastes no time giving Chris and Becky a wake-up call - things have to change for the future of their family. Over the next three days, she teaches a completely new approach to managing their boys' behaviour and there's plenty of kickback along the way. Will Chris and Becky be able to keep up the new regime?
