Growth refers to an increase in size through structural changes, while development is a series of progressive changes that occur in an orderly pattern through maturation and experience. Development follows certain sequences, such as proceeding from head to toe (cephalo caudal) and from center to periphery (proximo-distal). Growth and development are influenced by both hereditary and environmental factors like nutrition, home environment, education, and hormones. While growth mainly deals with physical changes and is limited to early life, development encompasses all aspects of personality and is a lifelong process.
