What might indicate a need for developmental assessment in young children?

The choice indicating substantial delays in meeting developmental milestones is correct as a sign that a developmental assessment may be necessary. Developmental milestones are specific skills or tasks that most children can do by a certain age, such as crawling, walking, talking, and social interactions. When a child shows considerable delays in these areas, it may highlight underlying issues that require further investigation.

Identifying these delays early is crucial for supporting a child's development effectively. Timely assessments can lead to early intervention strategies that help address any challenges a child might face, ensuring they receive the appropriate resources and support needed to thrive. In contrast, consistent progress, a wide range of interests, and successful peer interactions suggest that a child is developing typically, which would not warrant immediate concern for a developmental assessment.
