Pretty much bronchiolitis is the viral (non-bacterial) form of bronchitis. If not managed, it can lead to bronchitis which is so much worse.

Our doc recommends using ventolin to remove the mucous (which is what can lead to the bronchitis) and after 3 days if there's no improvement, a steriod (cortisone) around lunchtime to boost the immune system during the circadian rhythm downtime at night.

Having said that, it's what my doc recommends and works for us. As Pip's in daycare, we needed a prescription to get them to dose him with the ventolin.

Unfortunately, it's something we deal with a couple of times a season, it just keeps coming back. And for us, as Kris mentioned, I will often sleep with Pip on my shoulder on my jason recliner to let him breathe during the night.

Good luck.
