hi MrsGuyof - yes, its really awful. I didnt know much about asthma and just thought he was suffering extra bad hayfever a couple of years ago until I took him to the doc and they gave him steroids, and the peak flow monitor hardly moved!
I am very careful now, he has daily piriton, and eye drops, but this week has been gasping into the inhaler. It happens so quickly, it must be taken seriously. Great to know your DS is not so bad at the moment though.
