The first programme meets two couples who can't stop having babies, and asks why not. Noel and Sue Radford from Morecambe in Lancashire have 14 kids and are expecting baby number 15. Sue has spent half of her adult life pregnant and over the last 17 years has had a baby nearly every year. Thirty-six-year-old Sue loves everything about babies and is happy to keep adding to her massive family. Tania and Mike Sullivan from Kent have nine children between them and Tania is now expecting twins. As strict Catholics, the Sullivans believe that children are a blessing from God and contraception is wrong. They feel the number of kids they have is not down to them. Pregnancy for Tania doesn't come easy and over the years she has had eight miscarriages. Due to her age and medical history, and because she has had so many children, her pregnancy is considered high risk. This programme follows the highs and lows of life in both super-sized families, including a family holiday for 16 and a look at how feeding everyone is like running your own canteen. Finally, the show witnesses the arrival of yet more additions to these mega broods.
The second film meets two big families with serious sibling rivalry. The Lewis family from Bournemouth have 12 daughters, many of them vying with each other in beauty-queen shows. But what effect does all this competition have on the girls? And then there's the Bland family, where children from different relationships are struggling to live together harmoniously under one roof.
In the final film, Price and Prejudice, three supersized families are asked whether bigger is really better? The film follows mother-of-13 Jo Watson, who lives on benefits and has been dubbed 'Britain's Most Prolific Single Mother' by the papers The Hamlins, a family of 12, refuse to take handouts but are often accused of being scroungers. And the 14-strong Hanns pay their own way, but are accused of being a drain on the environment.
