I don't 'exactly" know what I'm talking about, but I am dealing with pneumonia in my 1 year old right now. He was actually recently hospitalized for it so I'll tell you what I've gathered from all the Dr. visits, etc. Actual "Walking Pneumonia" is different than regular pneumonia and should be treated differently, this is determined with a blood test. There is a thing going around right now called "Bronciolitis" (not Bronchitis) and it causes a cough and can cause regular pneumonia and lasts about 6 weeks from start to finish. Hope that information helps. My son does not have Walking Pneumonia and he does not have a cough. He has been doing 4 breathing treatments a day and recently had his antibiotics switched. I wish he dID have cough, at least then he would seem sick! haha! Good Luck!
