Your babyââ¬â¢s brain is built over time: It starts during pregnancy, and continues through to early adulthood. And like a building, it needs a strong foundation. The brain is made up of several different areas that control everything we doââ¬âfrom hearing and walking to problem-solving and how we feel. Each area has millions of brain cells, or neurons. These neurons communicate with each other by passing chemical messages over tiny spaces called synapses. As the messages are repeated over and over, more links are made and ââ¬Åneural pathwaysââ¬Â are formed. Think of these pathways as the brainââ¬â¢s ââ¬Åwiring.ââ¬Â In the first years of life, these connections develop at an extremely fast pace.
