You have given an excellent history here but have not mentioned your son's age. I see that your heading indicates that he is a toddler.It is difficult to be sure about the diagnosis.I suspect that your son had croup to start with and now has a bronchial infection called bronchiolitis.This illness is caused by a virus so an antibiotic is unnnecessary. It would help your son to keep his nose clear with Salex drops and to nebulise him with Duovent or Combivent at least twice a day. If his vomiting continues please ask his paediatrician to see him again. His illness will last at least 10 days before you will start to see an improvement.
