5 monthly old sick with upper respiratory infection and it's killing me

5 month old daughter has a URI. Coughing, fever, sneezing, mucus. She seen pediatrician 2 days ago and was diagnosed with a URI.Her fever floats about 99-101 through out the day.Me and my wife know where she got it from and we're pissed a family member would bring an older kid sick her without telling us.It's just heartbreaking to see her cry and in pain and there's nothing we can do about it via /r/Parenting http://ift.tt/2EARyRI
