In the Here and Now Storybook (1921), educator Lucy Sprague Mitchell advanced the then controversial idea that books for very young children should imitate how they use language, since toddlers, who cannot yet grasp narrative or abstract ideas, seek reassurance in verbal repetition and naming. The most enduring example of this idea is Margaret Wise Brown’s 1947 picture book Goodnight Moon, in which a young rabbit names the objects in his room as he drifts off to sleep. Scholars note that the book’s emphasis on repetition, rhythm, and nonsense rhyme speaks directly to Mitchell’s influence.
