2 year old with a mucus cough

We are using the nasal spray and snot sucker faithfully and hylands cough & cough. I can hear all the mucus in her throat or chest when she cough. We’ve tried humidifier, What are some home remedies I can do?? She does have a fever and these are the exact symptoms she had when we took her to the doctor a month or so ago and they told us to just pretty much let it pass and give her Tylenol or Motrin for the fever.
