Language is complex, yet almost all infants acquire a language that they can speak comprehensibly in their first two-three years of life, in a relatively similar sequence of steps. The textbook also summarizes the use of infant sign language, and notes that some infants can communicate using signs before they can reliably communicate using single words. Discuss why signs may be easier to use than words in early language development and how this might happen based on your understanding of human development and communication. What might be the benefits of teaching signs to babies, and could there be any disadvantages?
