What percentage of children are classified as having an easy temperament?

• A. Approximately 40%.
• B. Approximately 10%.
• C. Approximately 25%.
• D. Approximately 60%.

Answer: (A)

In temperament research, the easy temperament is the most common pattern seen in infancy. Children with this style tend to have regular routines, adapt readily to new experiences, and maintain a generally positive mood. Across major studies, roughly four in ten infants fit this category, which is why the approximate percentage is about 40%. The other temperament patterns—difficult and slow-to-warm-up—occur less frequently, helping explain why the easy group stands out as the largest share of the population. This understanding helps clinicians anticipate parenting needs and guide expectations for early childhood behavior.
