The Three Day Nanny - Season 3

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?

Kathryn Mewes visits the Smith family and attempts to ban smacking and restore order in a house where communication has broken down and chaos rules. The Smiths have turned to Kathryn in a desperate attempt to regain some control over their unruly children - Alessandro, Carmelina and Luciano. The kids rule the roost fighting and biting anyone who gets in their way, while ignoring their mum when she pleads with them to stop. After a full day of mischief they then spend every night bed-hopping, meaning no one in the house has slept properly in years. When Kathryn arrives at the family home on Stockton-on-Tees, she first has to deliver some tough home truths for parents Anthony and Angeline - it's them who have to change, not the children. Kathryn introduces a range of clever techniques. But when the kids fight back, dad is put to the test.

As a single mum to four unruly children under the age of three, Rosie Parsons's situation is an extreme test for The Three Day Nanny. Two and a half year old triplets Summer, Sienna and Jacob were an IVF miracle and when 13 month old Zach came along Rosie thought she had the perfect family. But then her marriage broke down and she was left to cope alone with four extremely demanding children who fight for their Mum's attention. At home they hit and bite and often trash the house as they battle for attention, but it's the quiet triplet that usually wins - with her extreme clinginess and constant demands to be carried she leaves Mum with no hands free to tackle the naughty behaviour of the others.
