Comprehensive pediatric evaluation requires a combination of careful clinical observation, knowledge of child development and communication skills with parents and caregivers. From birth, a complete physical examination including neurological, cardiovascular, respiratory and musculoskeletal assessment of the newborn is essential, as shown in the  video newborn exam by N. Gold. In addition, the monitoring of developmental milestones allows the detection of delays or alterations in psychomotor, cognitive and social growth, which is essential in the child's health check-ups. It is key to distinguish between normal variations and warning signs. The child's interaction with his or her environment, muscle tone, response to stimuli and body language offer valuable clues. As the head to toe assessment video shows, systematizing the examination promotes safe and comprehensive care. Developmental monitoring and effective communication with the family strengthen prevention and early intervention.
