1. Infancy: This is the period from birth to 1 year of age. The average length of a newborn baby is 50cm at birth, and the fastest growth in the first year of life is about 25cm.
2. Adolescence: most girls start breast development at the age of 9~11 years old, followed by a second peak of physical growth and development within 1~2 years, the average height of girls can increase by 8~9cm per year, and this age group is about 11~15 years old.
