What do normative charts provide regarding infant motor development?

Normative charts are critical tools for understanding infant motor development, as they provide benchmarks for typical age ranges in which children are expected to achieve certain motor milestones. This includes information about when specific skills, such as rolling over, sitting up, or walking, typically develop. By presenting this data, normative charts assist caregivers, educators, and healthcare professionals in identifying whether a child is progressing within the expected timeframe, thus facilitating timely interventions if necessary.

While the identification of motor milestones by age is a significant aspect of normative charts, these charts may also incorporate elements of skill acquisition and the general progression of motor skill development. However, the primary function often emphasized is age-related milestones, making this option the most aligned with the core purpose of normative charts in tracking infant motor development.
