babies with bronciolitis

Sasha
So my 3month old daughter has been having a very dry cough as well as a runny nose for almost a week now and I saw no sign of it getting better so I ended up taking her to the hospital where they told me she had bronciolitis.I hadn't expierienced that with my first child so it was all very new to me...the doctors didn't make it seem to serious and to just go about the normal procedures as to how to help an infant with a typical cold but it all makes me extremely nervous and paranoid.My daughter is so small and the cough is so overbearing..I can't just see her energy is so low.Any moms experience bronciolitis with their babies? And if so how did you treat it/keep your babies comfortable? Also how long did it last????
