My little boy has repeats of bronchiolitis, and the inhaler has been instrumental in allowing him to sleep. It's worth chatting with your Dr about this treatment - basically the inhaler will prevent mucus from settling in his chest and going bacterial and into bronchitis. It's scary, but worth the treatment. My little one hasn't been diagnosed with asthma yet, even though I bring up my concerns every checkup. He's now 3.

good luck for your little man.
