Home-educators Becky and Ben believe that for their three daughters - aged 10, eight and five - learning should not just happen in a classroom but all the time, regardless of location. They go up against Richard and Emily, who follow a regimented parenting style based on a meticulous routine, which includes daily training on a running machine and music lessons for their sons, aged six and five. Completing this week's line up are Andi and Jon, who employ a `structured chaos" approach to bringing up their two sets of twins, aged six and three, and a son aged four. Presented by Anita Rani.
