Warm, responsive interactions such as talking, reading, singing, and shared play, beginning at birth, help shape the neural foundations for communication, literacy, and later learning. A new evidence brief looks at how strong early language experiences support not only communication but also executive functioning, social and emotional development, resilience, and well-being. It also outlines how parents, caregivers, and educators can create language-rich environments through responsive “serve and return” interactions and everyday activities, while also highlighting the benefits of bilingualism.
