Hello everyone! We've been living in a private house for 1.5 months. Our baby started having a stuffy nose after 40 days, on the first day he had dry cough and it was accompanied by vomiting. On the second day his temperature rose to 38.4, hoarseness in his voice, when he breathes you can hear wheezing. The doctor says that this is due to dry air, but if so, why did the temperature rise? Has anyone experienced something similar, what were they treated with or how did they manage?
