According to the Facts For Life website, the first five years of a child's life are the most important time for brain development. The experiences of a child during these years impact her ability to learn later in her life, as well as her physical and mental health.
The first few years of a child's life affect how the child learns and grows throughout her childhood. The Center on the Developing Child at Harvard University says that in the first few years of life, over 700 neural connections are made each minute. Since this is a time of extremely rapid brain development, healthy stimulation is crucial.
By the time a child with college-educated parents is three years old, her vocabulary is two to three times larger than a child with less educated parents. According to Harvard, an adult who had serious adverse experiences in her early childhood is three times more likely to develop cardiovascular disease in adulthood. According to studies referenced on the Think Progress website, a child without early childhood education is 25 percent more likely to drop out of high school, 40 percent more likely to become a teenage parent and 70 percent more likely to be arrested for a violent crime.
