Series 3

Supernanny heads to Hertfordshire, where single mum Tara Howat is being driven to despair by her aggressive four-year-old son, who swears like a trooper and humiliates her in public. Rhys and his seven-year-old stroppy sister Shannon are locked in combat with mum. Meanwhile, eight-year-old good girl Casey gets overlooked in the chaos. From the minute the family wake up right until bedtime, the family are battling to be the boss. Rhys won't walk to school properly and runs off in public. Shannon swears, throws tantrums and hits her mother. Mother Tara's behaviour is not much better - she spends the entire day shouting at her unruly bunch - although only good girl Casey listens to her. Jo's aim is to put a stop to the aggressive, dangerous and downright disrespectful behaviour of the Howat family. And that means Tara needs to put a lid on her temper.

Watch out Warrington! Supernanny's in town and taking on two brawling brothers, seven-year-old Louis and five-year-old Rhys. They have no respect for either mum Steph or each other, but when overbearing dad Simon's around it's a different story. Baby Lucie must be wondering what sort of a family she's been born into. The battle to control these badly behaved boys is only half of Supernanny's challenge. She's really got problems when their body building doorman dad decides he's had enough. Supernanny has to square up to Simon, shake up Steph and sort out the brothers' behaviour problems.

Stuart and Sarah Bates had two lovely boys and dreamt of a girl to complete their brood. But when identical twin terrors Erin and Orla arrived, they turned the family upside down. The three-year-old girls look like sugar and spice - but they sure aren't nice - kicking, scratching and bullying their way around the house and lashing out at their local nursery. Dealing with double trouble from dawn till dusk has manic mum Sarah at her wits' end, while sons Callum (5) and Haydn (7) get overlooked in the chaos.

Supernanny heads to Birmingham where four feisty children - and their dad - are driving mum mad! Six-year-old Tyler punches his mother Natalie and lashes out at his sisters. And Tia, the four-year-old baby of the family, kicks, scratches and tantrums if she doesn't get her own way. Sisters Bethany (7) and Lori (5) try to tow the line - but it's hard to behave in such a hectic home. Getting all four kids washed, dressed and out of the house is a daily ordeal, while bedtimes are a disaster. Mum Natalie battles to stay in control while father Martin buries himself in his hobbies. Contending with four feisty kids and parents who constantly undermine each other won't be easy.

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.
