This article does not diagnose fever or provide medicine doses. Its goal is to help families measure, record, call the right place, and recognize when not to wait. Younger babies need especially cautious assessment, so follow the thresholds and instructions from the baby's clinician.
Key takeaways
- 01
Working digital thermometer with batteries
- 02
Baby's age, weight, allergies, and medicines
- 03
Clinician, hospital, emergency, and 115 numbers
1. Prepare an information kit before illness
Save the pediatrician, nearest hospital, emergency department, and 115 numbers. Note recent weight, allergies, health conditions, current medicines, and where records are kept. Learn the digital thermometer instructions while everyone is calm.
2. Use the same order when calling
Start with the baby's age, then temperature, method, time, and accompanying signs. Report feeding or drinking, changes in wet nappies, and how alertness differs from usual. Do not start or combine medicines without instructions appropriate for the baby.
3. Signs that should not wait for a message
Seek urgent help for difficulty breathing, seizure, extreme difficulty waking, unusual blue or pale colour, refusal to feed, persistent vomiting, or clear dehydration. Fever in a baby under three months needs urgent clinical assessment under official guidance. For immediate danger, call 115 or go to emergency care instead of waiting online.
