Developmental assessment plays a crucial role in pediatric outpatient care. By regularly monitoring a child’s development during routine check-ups, pediatricians can detect any delays or concerns at an early stage, enabling timely interventions that support optimal growth and overall well-being. Developmental progress is evaluated against age-appropriate milestones to identify any red flags. Parents can use tools like the CDC Milestone Tracker app to monitor their child’s development at home and should discuss their observations with the pediatrician during follow-up visits. For high-risk infants, developmental assessments are recommended every 3–4 months during the first year of life, with subsequent evaluations scheduled as advised by the pediatrician based on the child’s progress.
