I do suggest taking her to the doctor especially after a week. Humidifiers are great, a steamy shower with the bathroom door closed works great especially when you put in the shower the Sudacare tablets that release a menthal aroma that does make breathing easier. If the nose is congested, try "Little Noses" A saline gel for littles ones that really do help little congested noses. It is also completely safe. I have had doctors recommend the saline gel.
