      "sample": "7 parent–child pairs; children aged 12–33 months; reading at home.",
      "finding": "Parents and children smiled and laughed more with personalized than matched non-personalized books. Vocal activity was higher than with the child's favorite book.",
      "limit": "A small study of immediate shared-reading responses; it did not measure lasting reading habits."

      "limit": "Learning was low in both conditions. Format, reading context and adult interaction matter."
