Watch Jo Frost Extreme Parental Guidance online: Episode 3 Regan and Josh

Jo tackles two of today's toughest and most controversial parenting issues, attention-deficit-hyperactivity-disorder and obesity. In Middlesex she meets a family struggling to cope with seven-year-old Regan, who has recently been diagnosed with ADHD. In Manchester she visits Josh, a ten-year-old boy already classed as obese. And in a revealing study, Jo investigates how young girls really feel about their bodies. With the number of children admitted to hospital with eating disorders rising by 80% over the last 10 years, Jo joins forces with Professor Teri Apter of Cambridge University to find out what mums and dads can do to protect their daughters. Groups of girls aged six, nine and twelve, all with healthy body weights, are invited to have their photos taken before the images are digitally altered to show three bodies getting thinner and three getting bigger. Each girl is asked which image they thought was accurate and in contrast, which one they'd most like to look like. The startling results reveal many perceived themselves as being larger than they really are and that many already wanted to be thinner.
