Hello everyone! A few days ago my son had a fever for two days at 38 degrees. I brought it down with ibuprofen and this was accompanied by frequent dry coughs. We called an ambulance and they found his lungs clear, the throat red. And it turns out that this is on top of teeth, two upper ones are erupting. I gave him lots of water, monitored the humidity in the room. In general, the cough didn't bother him much. But today he started coughing more often and can't sleep properly because of it. What can be done? How can I help?
