Many children get RSV (virus) bronchiolitis during their childhood. It is especially harder to deal with young infants.
Kids with bronchiolitis produce lots and lots of mucus. This mucus causes breathing difficulty and poor feeding along with other complications.
What you can do at home is use normal saline drops, suction with bulb suction or other nasal aspirators like NoseFrida, have humidified air.
Monitor closely for respiratory distress (nostrils flaring, using extra rib muscles), wheezing, dehydration, poor feeding, and lethargy. Take baby to the ER with any of these concerns.
