Zac has had croup every winter since he was 2. The first bout was horrendous and required hospital treatment. After that we were told how to treat him at home and how best to manage his allergies during Autumn and Winter. We bought a steamer for his bedroom and whenever he had a cold we switched it on in anticipation of the midnight bark. His blue inhaler helped too, along with regular doses of Calpol and keeping him upright.
With each bout we got better at treating it and each episode was less severe than the one before. However, he is still prone to bad coughs and sore throats, at any time of year, and we are always told that this is just a side effect of his asthma and inhaled allergies. Happily, even they have started to improve.
