Each one can produce almost 15,000 synapses. Those synapses that are used repeatedly tend to become permanent. Those that are not activated tend to disappear. It is also in the first three years that the child makes the most dramatic gains in language. There is an explosion in vocabulary and sentence use.
Children bring all that they know without words to the task of learning language.
The child's early experience of the world is active. He or she seeks order and to understand the basic functions of the objects and people in the world - what one can do with things, what things can do, and the flow of how different people interact with each other. Pathways for language will be cultivated. When we communicate with our children, which involves both speaking and listening, we are teaching far more than words and sentences. We are letting them know that what they have to communicate and share is important, that they are important, and that we value their contribution.
