My 2 year old has started wheezing again. He has had really bad episodes of wheezing in the past, doctors have given a nebuliser with a preventer pump and a blue pump called salbutamol he uses the brown pump daily but I've taken him off the blue pump as they have not diagnosed my son with asthma and I don't want him to rely on it also it makes him extremely erratic and angry. I really don't want to put him on the blue pump again as he has not had it for a while, are there any suggestions for a more natural way of relieving him from the wheezing. 
Thank you
