Four-year-old Cameron is so aggressive and disruptive that Supernanny's renowned naughty step isn't even an option. He's so out of control that his young parents Nicky and Chris Smith-Clarke have been given three weeks notice to find a new nursery for him. Cameron's rages are so extreme that the other children fear him, the other parents avoid him, and Nicky and Chris are at a loss as to what to do. Parenthood has been very challenging for Nicky and Chris. Tragically, they lost their second child to cot death when Cameron was two and since then things have spiralled out of control. Still grieving, mum Nicky finds it difficult to enforce any sort of discipline, while her husband Chris's approach is the very opposite, and therein lies the rub. It's going to take more than a stern word from Supernanny to get this boy back on track.

Dr Stephen Brickley and Dr Ann Gormley both have PHDs in neuroscience, but when it comes to controlling their two sets of twins - all under the age of five - they've run out of ideas. After years of trying for a baby, Ann and Steve had IVF treatment and were overjoyed when they found out they were expecting twins. But just one year after the arrival of Aiden and Ella, the news that Ann was pregnant with more twins didn't go down quite as well. Steve works five days a week, leaving Ann at home, but with four children under the age of five, she feels decidedly outnumbered. Aiden and Ella, who are almost five, are at loggerheads, while toddlers Louis and Ciaron give mum the run-around and refuse to eat anything other than jars of baby food. The hurdle of taking their children beyond the toddler stage is too much for Ann and Steve. All four children still drink milk from baby bottles, and they're all still in nappies at night, even though Aiden and Ella are in school by day.

Supernanny goes to the rescue of the Wynne-Jones family in North Wales. Mum Lin is being driven round the bend by four feisty children and a football-mad husband who will do anything for a quiet life. Thirteen-year-old Simone and Andrew, 10, are constantly bickering and coming to blows. Four-year-old Ben runs riot, won't stay in bed and has a dangerous obsession with electrical appliances. And then there's Georgia, a cheeky two-year-old, who's fast turning into a little version of her brother. The house is littered with locks to keep the kids in - or locks to keep kids out - there are even locks to ensure the kids stay in bed. Lin is a nervous wreck and Dad Ronny can't stand the racket. Their ten-year marriage is feeling the strain and Supernanny is their last hope. There's a lot to sort out, even by her standards, but she's going to give it her best shot.

When Supernanny met Meghhan, they didn't hit it off. The eldest of three girls, nine-year-old Meghhan was ruling the roost with her demanding, bossy, explosive temper. Her whole family were at the mercy of her moods, parents Paul and Denise were at their wits' end and woe betide younger siblings Gabriella and Erin if they dared to cross their big sister. Meghhan felt so threatened by the change that Supernanny represented that she fought her tooth and nail. Two years on, Supernanny is back to see whether her training has kept the tantrums at bay.

When Doug and Sandra Douglas were in their mid-forties, they became first-time parents - to twins - and were overjoyed when their baby daughter and son arrived. But by the time little George and Nicole had started school, incessant tantrums, biting, swearing and kicking from both twins was driving their parents to despair. Supernanny Jo Frost took the twins in hand and turned their behaviour around. Two years on, she's back in Staines to see whether the family have stuck with her training.

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.

Jo takes on the four unruly young Collins children, who run the house by mob rule. She finds herself particularly up against it with nine-year-old Ben and four-year-old Joseph, who are not only aggressive and destructive, but are determined to be the first children to prove that Supernanny can fail! After witnessing everything from regular use of the F word to spitting and smashing up the house, Jo introduces her new zero-tolerance regime, under which all bad behaviour is punished. The children are separated into different Naughty Zones when they misbehave, and have toys and any luxury items confiscated. She encounters much resistance from the kids, and tears from mum and dad, and even has to teach dad how to better handle his children using a bit of imaginative role-playing.

Kathy Webb is a working mother. Arthur Webb spends much of each day on the road. They have three young children, one of whom has Down's Syndrome.

This episode's family consists of mum Caroline, dad Sunil and the four junior J's - Jaimin, Jasmine, Jenna and Jayan. All the children are under the age of eight, and look like butter wouldn't melt in their mouths. But under closer inspection these kids are mini-adults long before their time. Supernanny Jo Frost has a different kind of mission in this house: reminding everyone who the parents are - and who are the kids. Her techniques include setting up no-go zones and the introduction of a bedtime routine for the first time ever, with new rigid times for each child.

Older parents Doug and Sandra struggle with their four-year-old twins, George and Nicole. This pair of tag-team terrors have been known to have four-hour tantrums. The twins are at their worst when out in public. They often resort to kicking, screaming, lying down in the street, throwing items around the supermarket and generally causing such embarrassment to their parents that they just do not know what to do. Now these beleaguered parents are pinning all their hopes on Supernanny Jo Frost. Mum in particular is hoping that Jo can help her to turn things around, as she feels that her four-year-olds only ever listen to dad. Jo's clever techniques for the 'terrible twosome' include: a shopping involvement technique, tantrum control - with a calm-down zone and reward charts.

Supernanny needs to draw on all of her 16 years experience of nannying when she meets Paul and Denise Cooke and their three daughters: four-year-old Erin, six-year-old Gabriella and nine-year-old Meghann. All the girls are very bright and creative but their arguments with their parents regularly turn into shouting matches. Meghann's relationship with her mum is very stressful and the family hardly ever go out in public together for fear of an embarrassing scene. Supernanny adapts her tried-and-tested techniques to fit the Cookes' problems, with the renowned naughty step replaced by a bigger reflection room for all the girls, and attempts to improve the mood and reward good behaviour.

When Jo Frost meets Debbie and her daughters she's confronted by some of the most shocking behaviour she's ever seen. Debbie is a single mum who juggles two jobs with bringing up her three daughters, Bethany (5), Ruth (3) and Hannah (2). When Supernanny arrives, she's spat at and has things thrown at her - and mum doesn't do much to stop it. After laying down some household rules Supernanny adapts her famous naughty step into three 'naughty corners'. Then she teaches Debbie a 'roaming technique' to help mum regain control of the girls in public, before addressing bedtime with a strictly no-nonsense stay-in-bed technique - which eventually works after Ruth gets out a record 47 times. It all goes well at first, but then Ruth deliberately bangs mum's head against the kitchen door...

Jo Frost really has her work cut out when she meets Stuart and Laura, a kick boxing couple, and their three kids, five-month-old Diesel, two-and-a-half-year-old Tegan-Olivia and five-year-old Matthew, whose aggressive and violent behaviour often leaves mum battered and bruised. When Supernanny arrives she sees how bad the situation is. After laying down some household rules, Supernanny introduces a special 'work out your anger' chart and a chill-out chair to tackle Matthew's tantrums. Supernanny then encourages mum to let go of the reins and allow Stuart a more active role with Matthew, before leaving them to implement the techniques by themselves. It all goes well at first, until Matthew stages an epic one child riot leaving the house looking as if it's been burgled.

Jo Frost goes head-to-head with a seven-year-old girl who holds her whole family to ransom. Can Mum overcome the fear of her own daughter? Or will her little rebel reign supreme? Wendy Agate is struggling to bring up her three girls: 10-year-old Marie, nine-year-old Amie and seven-year-old Maryann; largely because of her youngest daughter's shockingly bad behaviour. She calls her mother a 'fat bitch', attacks her sisters, runs out of the house and across the road, and keeps everyone awake at night with screaming fits. Supernanny confronts Wendy, and then spells out how things are going to change: a reflection room for when the girls misbehave, a trust technique to allow the girls to go out to play safely, and a video diary room where the girls can express their feelings without blowing their top. Things start to improve - until Maryann uses the video to tell mum what she really thinks of her...

Supernanny Jo Frost is called in to tame the Young family of five boys. With so many kids in the house, it's a case of mob rule, and the parents are desperate for help.

Thirty-three-year-old Michelle Ball lives in South London with her two sons, three-year-old Ryan and one-year-old Kyle. Michelle used to be an outgoing woman brimming with confidence and ambition. A Latin dance champion, she lived life to the full. But four years later she's a full-time mum and things couldn't be more different. Even though he's three, Ryan is still in nappies, acts like a baby and is violently jealous of his little brother Kyle. Even with Gran's full-time help, Mum doesn't have a minute for his baby brother, and even less for herself. Can Supernanny Jo Frost put an end to the misery and give Michelle her life back? Jo shakes up the household by sending Gran away, enforcing a strict routine, stopping Ryan demanding to be carried all the time, getting rid of the dummies and nappies, and imposing a proper bedtime routine. Things pick up until Supernanny finds Michelle in floods of tears.

Supernanny is called to deal with a food-phobic seven-year-old. But it's only when she witnesses a mealtime first-hand that she realises the extent of the family's problems. Heather and Alex Bixley live with their sons Brandon (7) and Zak (4). Brandon developed a negative relationship with food after having gastric flu as a baby. What started as fussy eating has become an obsessive fear that dominates family life. After six years of non-stop battles with Brandon, Mum is at breaking point, but Supernanny has some harsh words for her and Dad. She's horrified by the way they aggressively try and force Brandon to have food he doesn't want, and tells them they've got no chance of turning things around until they stop fighting between themselves. Supernanny introduces a menu of innovative techniques to change the boys' relationship with food, including her renowned 'little chef' technique - but the biggest hurdle is the bickering Bixleys themselves.

Supernanny Jo Frost returns to see how the Woods family are doing with their three children, 13-year-old Caitlin, 11-year-old Billy and three-year-old Charlie. Previously, Charlie completely controlled the household with his tantrums. Supernanny turned their lives around, using her renowned naughty step to discipline Charlie, involving him in tasks like getting dressed to stop him resisting everything, establishing a strict daily routine, creating a calmer bedtime atmosphere and encouraging Mum and Dad to spend quality time with all their kids.

The Woods family from Grantham call upon Jo for her expert advice and no-nonsense approach to child rearing. Their youngest child, two-year-old Charlie, is a raging toddler who is destroying and dominating family life with his out-of-control behaviour. Desperate times call for desperate measures; mum Lucy and dad Steve are determined to turn their lives around and adhere to the strict guidelines Jo has laid out for them, Charlie and their older children Billy and Caitlin. But even Jo, with 16 years of no-nonsense nannying and childcare practice behind her, admits it is going to be a challenge. 'I have never seen a boy run riot and control his family like he does... I am shocked to see how you have allowed him to become this bad.

Supernanny Jo Frost faces a tough assignment when she agrees to move into the home of single mum Kelly Steer. Kelly's two young children have pretty much destroyed the family home. Out of control four-year-old Callum and five-year-old Sophia dominate the house. They fight with each other, won't eat properly, destroy their bedrooms, refuse to sleep at bedtime, and worst of all, they have been known to physically attack their mum.

Life has been tough for the Charles family since the birth of their twins 15 months ago. Their once well-behaved four year old Jacob now lashes out at his younger siblings.
