Does my 15-month-old daughter have a lot of cold symptoms?

Yes, a cold can last 10 to 14 days in children. The best treatment for symptoms is nasal hygiene using saline solution and a nasal aspirator. This can be done as often as needed throughout the day. It is also suggested to apply Vicks ointment on the chest or back at night. Avoid using cough syrups as they do not address the root cause of the cough.
