Took ds to GP (again...) for his cough/ wheeze which was worse. Last night was horrific, nearly used out of hours doc as vomiting too. Took him first thing so they could hear wheeze cough at its worst. This time as well as yet another course of antibiotics this doc has prescribed a blue inhaler and aerochamber. If this is the thing that helps how long is it until we can expect to see a difference?
