Is this normal?
A fever is usually the body's natural way of fighting infection. How your baby is acting matters more than the number on the thermometer.
- Alert and making eye contact
- Having wet nappies as usual
- Still interested in feeding
- Under 3 months with a temp of 38°C+
- Difficulty breathing or blue lips
- A rash that doesn't fade under a glass
