If your child is coughing, her body is doing its job.
Coughing is a reflex that clears fluid from her throat and chest. It happens when nerve endings in those airways get irritated.
Coughing is one of the most common symptoms of colds and other viruses, including the flu. It can start suddenly and last for several weeks. But like all viruses, it can’t be cured with antibiotics. A viral infection just has to run its course.
