Red flags
- Faltering growth or falling off centiles without a clear feeding story
- Poor head control or marked hypotonia beyond expected age for corrected age
- Developmental regression or loss of social smile/engagement
- Head shape with suture ridging, restricted growth of skull, or raised intracranial pressure signs
- Unsafe sleep environment continuing despite counselling (prone sleep, soft bedding, shared soft surface)
- Maternal suicidal ideation, inability to care for the infant, or suspected abuse/neglect
- Unwell infant at a 'well' visit — treat as acute illness first

Health supervision
Sick visit in the same age band
Visit length and content matter. Rushed visits lose family-centred content and leave families less satisfied; protect time for concerns, not only for needles. [9]
Overview & Definition
Picture a four-month-old on the examination mat. The mother says sleep is broken and the head looks flat on one side. The father asks when solids start. The infant smiles, holds the head up prone, and has doubled birth weight. That is the 3–6 month health-supervision window: still fully milk-fed for most infants, gaining head control and social engagement, still at peak risk for sleep-related death if the sleep environment is wrong, and still tightly bound to caregiver mental health. [1] [3] [4]
Infant health supervision in this band means planned preventive care that covers growth, development, physical examination, anticipatory guidance, immunisations and family context. It is not the same as a brief “jabs only” encounter. Bright Futures and equivalent child health programmes organise age-specific priorities so you do not invent a personal checklist each time. [9]
This page owns the 3–6 month leaf. Birth-to-3 months, 6–12 months, safe-sleep deep-dive, immunisation schedules and general developmental screening tools are adjacent topics — cross-link them rather than rewriting those chapters here. [5]
