While previous accounts of the function of food in children’s literature have mainly focused on fiction, this article examines nineteenth-century poetry and drama where ‘bad eating’ is constructed as a form of anti-social behaviour that children should be warned against and should learn to despise in others as well as themselves. Poetry for children, throughout the century, is designed to be repeated orally, often learned by heart and thus internalised: its emblematic characters, secured in memory by rhyme and metre, therefore have particular staying power in childhood consciousness that makes the trope of the ‘bad eater’ especially durable. Theatrical representations, likewise, serve to set the image of the unruly child eater within comic traditions that offer his or her body as an absurd spectacle at which the audience can confidently scoff. These tropes and images have a literary longevity that both reflects and sustains aspects of blame around ‘anti-social’ eating, which children internalise from a young age.
