By showing that parent-child verbal interactions in early childhood predict critically important outcomes through age 14 years (∼10 years later), the authors of this study have made a major contribution to this topic, with strong implications for American Academy of Pediatrics policy and clinical practice recommendations.8–10 With these findings, the authors also … Address correspondence to Alan L.
