Children can become unwell quickly, so certain signs always warrant emergency care. Call your local emergency number or go to the emergency room if a child has difficulty breathing or is breathing very fast, has blue or grey lips or skin, has a fit or seizure, is unusually drowsy, floppy, or hard to wake, has a rash that does not fade when pressed with a glass, has a stiff neck or dislikes bright light, or is showing signs of severe dehydration such as no wet nappies, sunken eyes, or no tears when crying.
A fever in a baby under three months should always be assessed urgently, as should any baby or child who seems very unwell, is not feeding, has persistent vomiting, or whose condition is rapidly worsening.
Parents and carers know their child best, if your instinct tells you something is seriously wrong, seek care even if you cannot name the exact problem. For milder illnesses, telehealth or a pharmacist can help guide you, but never delay in-person care when red flags are present.
