The first five years of life are a very important time for children's language acquisition and development. By the time children are old enough to start school, they have already learned much of their language. Sometimes, however, there are differences in children's vocabulary development. Differences are expected but there are typical developmental patterns and they are presented next. Related information is also available under Developmental Milestones for Children's Literature, Reading, and Speech Language Development.
