Babies & Children

Symptoms in babies and children: fever, rashes, coughs, crying, feeding problems and tummy upsets. Children become unwell quickly and recover quickly, and these pages focus on the behaviour and warning signs parents are usually advised to watch for, and when to seek help the same day.

This page lists all 14 of them in the guide. Open any symptom for its possible causes, red-flag list and frequently asked questions.
