Good evening girls. The baby started coughing. A wet cough. I'm ventilating the house, humidifier 24/7. I'm giving him water more often. Called the pediatrician, she said I'm doing everything right and there's nothing else to do. But the cough doesn't go away, and it seems to be getting worse. Still wet. What did you do when your little ones had a cough?
