A barking cough in children could be a symptom of croup, which is often caused by a viral infection affecting the upper airways.
It can be very disturbing for the child and care takers.
If your child has a barking cough, especially if it’s accompanied by difficulty breathing or a high-pitched sound when inhaling, it’s important to consult your pediatrician immediately.

They can assess the severity and recommend appropriate treatment, which may include humidified air, fluids, or medications.
Avoid to self medicate as this can sometimes lead to complicated situations. In few occasions, children might have to get admitted in the hospital for more frequent medications and monitoring.

Kindly contact your child’s pediatrician for any queries if such scenario arises.
