DS1 has spasmodic croup which is different from normal croup in that it can be caused by any minor cold virus whereas normal croup usually only happens with more serious infections that are accompanied by fever. Spasmodic croup can also be caused by allergies or changes in weather. Most kids grow out of spasmodic croup by the age of 6. We also have predmix in the fridge and administer that at first signs of croup without having to consult the GP each time as he gets croup every time he has a minor sniffle. :hugs: it is hard to see them suffer with croup so often.
