Progress monitoring should begin early in a child's life, starting from infancy. The American Academy of Pediatrics (AAP) recommends that children have well-child visits at regular intervals, including at 1, 2, 4, 6, 9, 12, 15, 18, 24, 30 months, and annually thereafter. Developmental screenings are typically conducted at 9, 18, and 24 or 30 months, with additional screenings as needed based on the child's risk factors and health history.
