Early childhood change occurs between which ages?

• A. Zero; eight
• B. One; five
• C. Five; ten
• D. 18 months; four years

Answer: (A)

Early childhood covers a broad span from birth through roughly the end of the early elementary years, about eight years old. This is a time of rapid changes across movement, language, thinking, and social-emotional skills, as children grow from dependents into more independent, school-ready kids. That’s why the range from birth to around eight best captures the entire period of early childhood change. Other ranges either start too late or end too soon to include the full development happening in this stage.
