Symptoms of asthma include breathing complications, wheezing, coughing, and tightness the in chest (Marks, Pearce, Strachan, & Asher, n.d.). Some people may experience stronger symptoms during physical activity or at nighttime. Asthma attacks can be fatal when airways are blocked and oxygen fails to enter the lungs.

    Babies can get apnea, which is a pause in the child’s breathing pattern. Since the symptoms aren’t that noticeable, it is not often diagnosed until the more severe symptoms appear.
