Picturebooks aid children's developing social understanding because they are dialogic, relational contexts where child readers have opportunities to engage vicariously with a wide range of imagined others. We use research by literacy and literature scholars, including our own past work, to showcase a series of visual and linguistic elements in picturebooks that invite readers to co-create characters' consciousness via social imagination, the equivalent to a Theory of Mind in the world of story. We ground these relational and dialogical invitations by presenting an analysis of these elements in the picturebooks (in: Pak, "Dear Juno," Puffin Books, New York, 1999; in: Soto, "Chato and the Party Animals," Puffin Books, New York, 2004).
