How Does a Baby's Brain Grow and Develop?

The first three years are really important for building a baby's brain. It grows and develops faster than any other part of their body and is the fastest rate of brain development in their life.

During the first year their brain doubles in size. Babies spend 60% of their energy working out which brain neuron circuits work best. By year three their brain is 80% of its adult size and has over 1000 trillion neuron connections. It has now tripled in weight. 

By around 6 months they develop a perception of depth and a sense of colour. Their eyes begin to work together to form a three-dimensional view of the world. Everything they touch, taste, see, hear and smell helps to shape their brain. 

Every baby's brain is different and is influenced by their individual experiences. They are influenced by the actions of parents and siblings; pointing, waving, making faces and smilling. These are actions that are based on repetitive familiar experiences.
