At our clinic they put kids on it at the first sign of pulmonary involvement, or by age 6, whichever comes first.
Emily was late to dx (7.5) and was gradually changing other stuff so didn't start it until 6mo ago (I didn't want to change more than one therapy at a time so this came later.) We saw a BIG difference when she did. Her pft's went up by more than 10% and for the first time in many years, she's had colds that DIDN'T progress to needing antibiotics. That alone to me is nothing short of amazing, and would make it worth being on, even if her pft's didn't go up!
I know you want experiences of those with babies/very young children, but I only wanted to add our experience because I think the role this med can play in being able to make mucus easier to clear can help reduce infection (and therefore also the need for abx) ...and that can really be of benefit to the little ones. And stopping the damage infection causes right from the start is also crucial.
