Bronchiolitis is an infection of the small airways of the lung (the bronchioles). It is a common condition of babies. Most affected babies are not seriously ill and make a full recovery. Sometimes it becomes more serious and hospital care may be needed.

Fast breathing, difficulty with breathing and wheezing may develop.
The nostrils may open out (flare) and you can often see the muscles between the ribs moving inwards during each breath. This is because the baby needs more effort than normal to breathe.
The baby may have difficulty feeding and taking drinks. This is because the baby is ill and becomes tired easily. The baby may struggle to breathe and to feed at the same time.

Any child who seems to be struggling to breathe or not drinking well needs to be seen urgently by a medical professional.
