Case of acute bronchitis in a baby

A 6 month old baby got wet in water and was put in an AC environment when wet; she developed low grade fever with nose watering. The lungs were congested making her breathing difficult, sputum which came out was thick and stringy. The baby was vomiting all the food and would not eat. Mom called me late at night yesterday.
Mostly the diagnosis seemed like a RSV infection.
Sarted her on ipecac, ars alb (exposure from cold causing flu) and hydrastis (congestion with thick stringy sputum).
Baby was able to breathe better in 2 hours. Was abe to drink some milk and sleep through the night. Next day sputum was coming out easily and baby was also eating well.
