Rachel Riley, at 12 weeks' pregnant, gets a glimpse of her own future as she heads to North Yorkshire to care for four girls - a week of cooking, discipline, arguments and dance competitions.

Chelsea girl Georgia `Toff" Toffolo travels to east London to spend four days looking after the children of single mum Soniya, encountering a world very different from her own childhood.

Presenter Anita Rani has forged a successful career on shows such as Countryfile and Strictly Come Dancing, and it's left her in two minds about whether she wants to have children of her own. In order to experience the reality of twenty-first century parenting she throws herself in at the deep end: taking over full parental responsibility for twin nine-year-old boys Luke and Daniel, while mum Sue enjoys some well-earned rest and relaxation.

Constant domestic drudgery, breaking up arguments, organising garden parties and trying to find ever more inventive ways to keep the boys entertained, leaves Anita exhausted. While she struggles to adjust to life as a parent, Anita can't help falling in love with the boy's energy and lust for life, and despite her initial reservations, she soon finds her maternal instincts awakened.

Stephen Manderson, otherwise known as rapper and musician Professor Green, was brought up by his nan on a council estate in Hackney. Now he takes on the role of parenting three boys who are enjoying a very different childhood on a smallholding in the Cotswolds.

Stephen soon learns that his role as both mum and dad to William (12), Alex (15) and James (17) means being pulled in several directions at once. From arguments over the boy's computer games addiction to worming the family's sheep, Stephen faces an uphill battle. But with his patience and sensitivity eventually winning the boy's over, it proves to be an emotional experience for everyone involved.
