How long does RSV cough last?

I made a post yesterday that my 2 year old was just diagnosed with RSV and we’ve been using the snot sucker, vapor baths, humidifier and Tylenol for fever and hylands cold and cough. However, she’s still coughing. She is more of herself and playing a little and jumping off the couch but she’s still breathing rapidly while not being active.

I’m 28 weeks pregnant and I now have a headache, stuffy nose and feel like shit. I have been taking pregnancy safe meds for my symptoms which has made me feel a little better.

But I just wish my daughter will stop coughing.
