I posted to you below, and I see some of my questions I asked you, the answer is here. My son also had bronchiolitis(rsv
)and then several colds one after the
other. He is 7 months. The
ped. said he had RAD from what the x-ray showed but said that it could show but never suffer symptoms, or a chronic cough maybe the only symptom, may not ever have wheezing again(which he had only when he had the RSV(bronchiolitis) infection. Nebulizer treatments did not work for him.
