It sounds like a contradiction: books with no words, recommended as books for preschoolers to learn to read. But wordless picture books are quiet pre-reading machines — because they hand the child the narrator's job, and narrating is where half of reading readiness gets built.

What the wordless book trains
When a preschooler "reads" a wordless book, they're doing genuine literary labor: sequencing (this happened, then this), inference (why is the fox hiding?), character logic, cause and effect, and — the crown skill — producing story languageout loud. Narrating pictures pushes a child into book-flavored speech ("one day…", "suddenly…") that everyday conversation never demands, and that narrative register is precisely what comprehension will later require. The emergent-literacy research at Reading Rockets consistently identifies oral narrative skill as a core foundation under later reading comprehension — and wordless books are its purest gym.
How to run a wordless session
Hand over authority completely: "This one has no words — YOU tell it." Then follow their version, however wild, asking only the light engine questions: "What's happening here? What do you think happens next?" Resist supplying the "correct" story; the child's authorship is the exercise. Reread the same wordless book across weeks and watch the narration grow — more detail, more connective tissue, more feelings attributed. That growth is comprehension developing in the open.
The confidence bonus
For the preschooler intimidated by print — the one who's noticed they "can't read yet" — wordless books are a masterstroke: a book they can read completely, right now, cover to cover, with total authority. Reading identity gets its first deposit years before decoding.
The shelf pairing
Wordless books work best alongside, not instead of, the worded shelf: the read-alouds supply the language models; the wordless titles give the child the stage to perform them. And the picture-narration habit transfers straight back — a child who narrates wordless books will happily "read" their beloved worded favorites from the pictures too, which is the same muscle, flexing.
