Thirty Million Words explains how everyday conversation actively shapes young children's brain development. Professor Dana Suskind combines research findings with real-family examples to show that interactive talk—not simply exposure to words—supports language, self-regulation, and readiness for school.

The book translates neuroscience into practical guidance and measured interventions used with thousands of families. It highlights which kinds of parent-child interaction produce measurable gains and offers clear habits caregivers can adopt.

• Take Turns — encourage back-and-forth exchanges

Accessible and action-oriented, the book provides tools for parents, early educators, and anyone who wants to strengthen the language environment that supports lifelong learning.
