Child development is the process by which the dependent infant matures into the independent adult, functioning within society. It is a complex interweaving of biology, psychology and environment where each skill builds on the ones that have come before and provides a foundation for those skills yet to develop.

Development in humans follows a predictable pattern and a rough schedule but no individual develops in exactly the same manner as any other. It follows an orderly pattern (unlike almost everything else regarding children); from top to bottom, central to outer and simple to complex. What is important, when considering normal development, is progress and parity; that children are moving forward in the different areas of development at roughly the same rate.

Disparity in progress between areas of the body (e.g. the right side and the left or the lower limbs and the upper limbs) or between domains of development (see below) is concerning, as is regression (i.e. loss of previously attained skills).

This article will outline the typical stages of development that children go through. The features typically seen at each age are described below.

Speech and language

We often talk about speech and language interchangeably, but they are two distinct concepts. Speech is the actual sounds of spoken language, produced by the co-ordinated action of the muscles of the tongue, lips, jaw and vocal tract. Language is the systems of words and symbols that we use to communicate with each other and encompasses written, verbal and non-verbal (gestures and body language) communication. Speech and language development relies on intact hearing, good muscle control and exposure to language, through interaction with other people.
