RSV home remedies!

My baby girl was diagnosed with RSV yesterday. She’s 9w5d. She seems to be doing really well but she sounds horrible! I believe we’re in the early stages of the virus, it has not moved down to her lungs yet. Her pediatrician projected that her worst day will be Wednesday or Thursday. I have this cold mist humidifier right on her and she is finally sleeping without that snotty noise. Anybody have any other home remedies to keep baby comfortable?
