Prior to the concept of physical development, let us imagine a process.
Consider a newborn baby. Right now s/he has no control over her/his movements, but within 18 months s/he will be walking, in another year running, and soon after, jumping and throwing and kicking things. In the first two years, a child develops physically at a faster rate than at any other time in her/his life. This physical development forms a significant basis for the developments in cognition and emotion.
Physical growth and development refers to a process which brings bodily and physiological changes- internal, as well as external- in a child from conception till death. Here, in this topic, while we are not going to discuss infant’s physical development in detail, it forms a foundation for a child’s development- not only physical, but also social, emotional and cognitive– in later years. Let us first discuss the characteristics of physical development during childhood and adolescence.
