Need advice from a girl. Still had sore throat before childbirth, treated it seemed to be gone. 4 days already as a terrible cough. Sore throat again. 2 days ago I took the child to the doctor, afraid that I might have infected him. They said the throat is slightly red, prescribed Ibuprofen and Veferon candles. Today I noticed that the child started coughing. To the doctor now after the holidays we have Hait. Who has been sick at such a time? I'm very scared because he's still very small. What did you do? Besides coughing, there's nothing else.
