Most people stop at two, a few brave souls go on to have three or four. But when it comes to having kids, there are a handful of families who are bucking the trend. This new three-part series explores the lives of some of the UK's biggest families. The first programme meets Noel and Sue Radford from Morecambe in Lancashire, whio 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. Tania and Mike Sullivan from Kent have nine children between them and are expecting twins. As strict Catholics, the Sullivans believe that children are a blessing from God, sex is part of marriage and contraception is wrong. However, Tania's medical history - including eight miscarriages - means her latest pregnancy is regarded as high-risk.
