Girls, can you tell me what to do for babies with a stuffy nose (runny nose)? I'm using a physical solution and Nazivin, but the effect is short-lived. The snot is full of my nose, I have an appointment with Dr. Loro only on Friday. We got sick on Monday evening, the doctor prescribed Nazivin and from the red throat. What should I do at night so that I don't sleep through it? It cries and doesn't breathe.
