The Three Day Nanny - Season 4

Professional nanny Kathryn Mewes helps restore peace and calm to households in distress. This time, in Luton, two-year-old Sebastian is literally banging his head against the wall in frustration. This toddler will also hit, bite and kick to get his parents' attention. Mum and dad feel powerless to control him. Kathryn finds out that Livia and Paul had a long and difficult journey to start a family. She needs to get mum and dad to stop wrapping their son in cotton wool. Easier said than done.

On a trip to Lincoln to help the Clemmit family, for the first time in her career, nanny Kathryn Mewes meets parents she feels may lack the basic skills for the role.

With their three-year-old daughter Bella totally ruling the roost, the Vernons, in the Wirral, have turned to nanny Kathryn Mewes in desperation. Simple tasks, like getting dressed or brushing teeth, are a guaranteed trigger for a tantrum - epic screaming fits that can last for hours at a time. With the couple failing to agree how best to manage their daughter's belligerence, cracks in the family are starting to show. Kathryn shows Mike and Emma how to regain control and focuses on improving the couple's relationship with their daughter. But with Bella railing against the new regime, will three days be enough to get the Vernon family back on track?
