Mom, tomorrow we're going to the hospital and tomorrow is 4 months old. But he has phlegm appeared, transparent. And such a feeling that mucus stands inside, but I think it's drool because he's choking on it. Suggest how to treat the nose, I applied a physical solution and cleaned it. Oh, until tomorrow I will go crazy.
