Hello girls, today for the first time in 4 months we started the flu? Our daughter has phlegm and dry cough. What can I give her? There's no fever. She feels good during the day, doesn't cry or fuss. But at night she has a stuffy nose and cries. We clean his nose with an aspirator. It doesn't help. What drops will help? I bought Ospamox, gave it twice a day. Can you share if anyone had it? Can we go outside in this condition?
