Consider the following scenario: Jessica is an 18-month-old in your classroom. She is not yet walking and can say two words: "No" and "mama." She prefers to spend time away from other children and does not express the range of emotions typical of her age group. Her parents insist she is just "shy." Keep in mind that teachers are not able to diagnose developmental delays, but they can suggest testing. Describe how you would handle this situation. How would you engage her parents in this process? How might her abilities impact your curriculum planning?
