If you are needing the rescue meds a lot, then it makes sense for the kids to be on a controller long term.
My older DD virtually never needs her rescue meds since she went on Flovent year round. In her allergy season, she steps up to a higher dose controller. Her asthma doctor says the goal now is to never have use rescue meds if at all possible.
She started using the spacer right away (around age 5) for her controller med. We have a nebulizer that we have used sporadically over the last several years, mainly when she has a severe illness. The nebulizer for her does work better for the rescue meds, but the way her heart races with the rescue meds we try to minimize it as much as possible.
