2 peak phases:
Weight and length grow the fastest in infancy, especially in the first 3 months, the first year after birth is the first growth peak, and after the second year, the growth rate gradually slows down until the growth and development rate of puberty accelerates! A second growth peak occurs.

Rate of development of each human body system:
The nervous system develops earlier and the reproductive system develops later. The lymphatic system grows rapidly in childhood and peaks before puberty and gradually declines to adult levels thereafter. The development of other systems such as breathing, circulation, digestion, and urinary is basically parallel to physical growth.
