What are developmental milestones?

Developmental milestones refer to normative events that indicate typical stages in human development. These milestones serve as benchmarks for evaluating a child's growth and progress across various domains—such as physical, cognitive, social, and emotional development—within expected age ranges. They help parents, educators, and healthcare professionals understand whether a child is developing in line with broader societal expectations.

For instance, milestones such as walking, talking, or counting are signs of reaching certain developmental phases that most children will achieve at roughly similar ages. This concept enables comparisons among children and identifies potential developmental delays or issues that may require attention.

The other options refer to aspects of development but do not encapsulate the comprehensive notion of milestones. While individual achievements pertain to personal growth, they do not specifically define normative stages. Emotional growth phases are focused exclusively on adolescent development and do not apply to all childhood stages. Factors influencing cognitive abilities are relevant to understanding development but do not directly define developmental milestones themselves.
