Sick baby 😩

My 11 month old is so congested and sick I’m so scared for her. I took her to the doctor Saturday and they said she doesn’t have rsv or flu. But she’s coughing so bad she can’t sleep and super congested. I’ve been running humidifier giving her cough medicine Benadryl, Tylenol as needed. Sucking snot out with nose frida every so often And even sitting in the bathroom with the hot water running but nothing seems to be working. She keeps running a low grade fever I’m just super nervous that she may have something now that we have left the doctors 😪 I literally cant sleep with her in pain like this I don’t think I slept at all last night because I’m so worried
