Small children are astoundingly flexible visual readers – they can take in packed scenes just as easily as bold, simple images; they can follow adventures in silhouettes against bright backgrounds and turn without a flicker to the comic-like abstractions of Mr Men. This openness is on a par with their acceptance of magical transformations, upside-down houses and flying through space, and their tendency to anthropomorphise everything, from rabbits to trains and from dinosaurs to umbrellas. They know no boundaries. They also linger over pictures, with a time-defying immersion that grown-ups tend to lose.
