Under normal circumstances, the breathing rate of a child of this age in a quiet sleep state is generally around forty times, with a maximum of no more than 60 times, and if it exceeds 60 times, it is considered to be shortness of breath. The most common cause of pathological respiratory conditions may be nasal congestion, because newborns breathe through their noses and generally do not open their mouths to breathe, so if nasal congestion causes the child to have shortness of breath. In addition, neonatal pneumonia may also cause shortness of breath in children, which is still relatively common and harmful.
