- Parents can be reassured if a child with a respiratory infection is playing, drinking, urinating normally, and acting like themselves.
- Warning signs that warrant a call to the doctor include irritability, lethargy, inconsolability, or unusual breathing patterns.
- Specific breathing red flags: chest or neck retractions, rapid breathing, wheezing, nostril flaring, head bobbing, or grunting.
- Hydration is another key indicator—if a child is not urinating at least once every 6–8 hours, this signals dehydration and the need for medical evaluation.
- These markers help distinguish between routine illness and situations that need urgent medical attention.
