PEDIATRICS CLERKSHIP - NEWBORN + GROWTH / DEVELOPMENT

YEAR 3 | PAGE 30A - AGE-SPECIFIC NORMAL -> ABNORMAL -> PREVENTION

WHY PEDIATRICS REQUIRES A DIFFERENT MENTAL MODEL In pediatrics, age changes the differential, normal vital signs, developmental expectations, medication/fluids, communication and disposition. Start every case with age and developmental context. A child is not a small adult: the same symptom can represent a benign developmental stage in one age group and a time-critical disease in another.

A. THE PEDIATRIC FIRST-PASS FRAME

Step	Ask yourself	Why it matters
1. Age + setting	Newborn, infant, toddler, school-age or adolescent? Well visit, clinic, ED or inpatient?	Immediately reshapes normal ranges, likely diagnoses, communication and urgency.
2. Growth + development	Is growth tracking? Are milestones being gained on time? Any regression or school/behavior concern?	Trend and trajectory are more useful than one isolated number. Regression is different from delayed acquisition.
3. Prevention + context	Vaccines, screening, nutrition, sleep, injury prevention, psychosocial environment and safeguarding?	Pediatrics tests prevention and anticipatory guidance as part of routine care, not as an afterthought.
4. Severity	Work of breathing, perfusion, hydration, mental status, fever-risk age, pain and toxicity?	A stable child allows stepwise evaluation; an unstable child needs age-appropriate stabilization first.
5. Weight-based decisions	What is the current weight and which treatment depends on kg?	Fluids and many medications are weight based; estimate only when true weight is unavailable in an emergency.
6. Family + disposition	Can caregivers recognize worsening, give treatment safely and access follow-up?	Safe discharge depends on the child plus caregiver capacity, return precautions and follow-up.

B. NEWBORN / WELL-CHILD HIGH-YIELD CHECK

Domain	Reasoning anchor
Transition + newborn exam	Look for respiratory/circulatory instability, congenital anomalies, feeding problems and findings that need immediate evaluation versus routine follow-up.
Feeding + weight	Interpret feeding effectiveness, output and weight trajectory together; distinguish expected early change from dehydration, poor intake or disease.
Jaundice	Age at onset, bilirubin pattern, gestational/risk context and illness signs determine whether this is physiologic-pattern jaundice or pathologic disease requiring workup/treatment.
Growth + development	Plot trends; screen development at recommended intervals; ask whether skills are being acquired, lost or uneven across motor/language/social domains.
Prevention	Use the current official immunization schedule and age-specific screening/anticipatory guidance rather than memorizing an outdated vaccine calendar.
Safeguarding	Ask whether injury/history fits developmental ability. Unexplained injury in a nonmobile child or inconsistent history requires careful escalation and supervised evaluation.
