My almost 4 year old has been coughing quite disturbingly for over a month now. We did see a doctor whom àssured us it wasn t pnemonia, prescribed ventalin with chamber to keep airway open to keep her from vommitting (which she was doing before, coughing, losing breath, then vomit). Said to know that she will still cough about another week to clear it out but after that, should be OK. She is still coughing and sounds like she has no breath only she s not vommitting. Any ideas?
