‘Peppa! Peppa!’ my daughter cries. We are in a shopping centre, but we could just as easily be on a high street, at a petrol station, or on the tube. Right now, she has discovered an inflatable Peppa outside a gift shop in Dublin. They say a shark can detect one drop of blood in 100,000 litres of water. Well, last month my daughter ran 40m across a crowded motorway services to scream and point at a tiny Peppa colouring set on a high shelf. To walk anywhere with her is like padding around parliament with a sniffer dog. There is no escape for any book, toy, activity pack or magazine that sports that flattened pink hairdryer face and stick figure arms.
