Why Developmental Milestones Matter
Developmental milestones are the skills most children master by a certain age. They help parents and pediatricians track growth in physical abilities, language, thinking skills, and emotional development.
While every child’s pace is unique, knowing these benchmarks helps spot possible delays early—when interventions are most effective.
