When to Call the Doctor About a Child's Cough
Is your child younger than 3 months old? Coughing is unusual in infants.
Did a violent cough begin suddenly without signs of a cold? Especially if your child is young, check to see whether a small object might be lodged in the windpipe.
Is your child also wheezing or having difficulty breathing? Has your child had a fever for more than four days? These symptoms could indicate pneumonia or croup.
Has your child 's cough lasted for more than 10 days? A chronic cough may be the first sign of asthma or sinusitis.
Does your child cough at night with no apparent cause? A persistent or recurrent night cough may occur several years before asthma develops.
