I have no idea what a "happy Wheezer" is... but my DD has wheezed since she was just a few weeks old, ended up in ED at 3wks with broncitus and developed many chest infections from then on including a bad case of pneumonia last year. Te pneumonia finally prompted the dr to give us ventolin to use when ever she developes a cold to widen her airways. It can't be diagnoised as athma until she is older but we are hoping she grows out of it like my DS did (arond 5) All the best with finding out more info
