My daughter has a runny nose, cough, and sore throat?

It sounds like your daughter may have a cold with symptoms like a runny nose, cough, and sore throat. It's important to maintain good nasal hygiene and consider using a saline solution to help clear her sinuses and alleviate congestion. Applying Vicks on her chest or back can also provide some relief. Coughing is common after a cold and may persist even after other symptoms have cleared up. You should start to see gradual improvement each day. If you have any more questions, feel free to ask!
