Which age group experiences very rapid growth and development?

Infants experience very rapid growth and development due to their crucial developmental milestones during the first year of life. During this stage, infants typically triple their birth weight and undergo significant changes in physical, cognitive, and emotional development. This age group is characterized by considerable brain growth, with important neural connections being formed as they learn to interact with their environment.

In contrast, while adolescents undergo growth spurts and significant changes associated with puberty, the pace of growth is not as rapid as that seen in infants. Children continue to grow, but their development tends to be more gradual and steady compared to the explosive growth observed in infants. Adults do not experience growth in the same way, as they have typically reached mature physical development. Thus, the period of infancy is distinctive for its extreme growth and development compared to other age groups.
