One of the measurements that can be used to determine a child's developmental progression is to compare the development of the child to the typical developmental milestones. Some examples of developmental milestones are when an infant first sits up, crawls, and walks. There are also developmental milestones for communication and emotional and social development.
Why is it so important to understand a child's developmental milestones, especially those for communication and social and emotional development? Review the developmental milestones from birth through five years and describe the ones you find interesting. Give reasons for your preference.

Centers for Disease Control and Prevention (CDC) provides some extensive information on developmental milestones for infants and young children. Google the keywords "CDC: Developmental Milestones." On the first Results page of Google, click the link “CDC - Learn the Signs. Act Early. Homepage – NCBDDD” to go to the CDC Web site. Once you reach the site, click the link "Learn more about milestones" to review the developmental milestones from birth through five years.
