In the context of child development, which of the following is the most fundamental and scientific distinction between the concepts of 'growth' and 'development'?

In the psychological study of child development, 'growth' and 'development' are two distinct concepts. Growth is related to changes in physical structure and size, which is primarily quantitative and stops after a certain age. In contrast, 'development' is a broad, holistic, and continuous process that includes physical changes as well as mental, social, emotional, and linguistic qualitative changes. Development proceeds gradually from conception to lifelong. For more information, Wikipedia reference can be consulted.
