6-24 months	38.0°C+ lasting >24h	See doctor if no clear cause; immediately if rash, breathing issues

How to Take Temperature Accurately

Rectal

Under 3 months

Most accurate; use a rectal-specific thermometer with lubrication

Axillary (armpit)

Any age for screening

Add 0.5°C for true reading; less accurate than rectal

Temporal / ear

Over 6 months

Convenient; must read in correct ear canal angle

Call 995 or go to A&E immediately if: baby under 3 months has any fever; child has difficulty breathing, purple/red rash, seizure, stiff neck, is unresponsive, or fever above 41°C.
