Case Scenario: You are the director of an early childhood program serving teen mothers and their children based in the local alternative high school. Your community is partnering with the high school to work with pregnant teens early in their pregnancy to provide education and resources. You are developing an interactive presentation for these teens that discusses factors that influence prenatal development and why this developmental period is critical. Framing your answers specifically for teen parents, please respond to the following: Describe critical periods and sensitive periods of development. Explain how biological factors can influence prenatal development and provide one example. Explain how environmental factors can influence prenatal development and provide two examples. Based on these environmental factors, what preventative measures would you share with these teens?
