Infant health supervision: birth to 3 months

Overview & Definition

A family brings a 10-day-old for a “check.” They want to know if weight is fine, if breastfeeding is enough, and when vaccines start. Your job is larger than a centile stamp. Early infancy is when jaundice peaks, weight bottoms out, milk supply is still establishing, sleep environments are set, and subtle congenital problems declare themselves. Health supervision in this window means planned visits that combine prevention, early detection and family support. ^{[15] [5] [6]}

Infant health supervision from birth to 3 months covers the period from hospital discharge through roughly 12–13 weeks of age. It includes the early post-discharge review (often day 3–5), the 1–2 week visit, the 1-month visit and the 2-month visit, plus opportunistic contacts. Frameworks differ by country — Bright Futures and the AAP periodicity schedule in the United States, personal health records and primary-care pathways in Australia and Aotearoa New Zealand, the Healthy Child Programme and NICE postnatal guidance in the UK, and tools such as the Rourke Baby Record in Canada — but the clinical tasks cluster the same way. ^[15]

This page owns ambulatory and medical-home preventive care in that age band. It links to dedicated pages for full immunisation schedules, safe-sleep depth, faltering growth algorithms and acute neonatal sepsis rather than hiding those whole chapters here. ^[15]
