Good day girls, the baby has a sore throat, runny nose, fever, cough. He called a doctor at home, he prescribed treatment. It's been four days now and the cough hasn't gone away, and it even got worse overnight. We can't sleep because of the coughing. The doctor prescribed only copious amounts of fluids so that the cough would go away. Girls, please tell me what you did to treat coughs in your child's age?
