What symptom did Bridgett's mother report that was concerning for her daughter's health?

Tiredness and shortness of breath are concerning symptoms in a pediatric patient as they can indicate underlying health issues, such as respiratory or cardiovascular conditions. These symptoms may suggest that the child's body is not getting adequate oxygen or that there is a problem with how the heart or lungs function, which can be serious.

In contrast, increased appetite and weight gain do not typically signify immediate health concerns but may warrant further investigation if they are excessive or uncharacteristic. Frequent coughing could indicate a respiratory infection or allergies but is less alarming than the combination of tiredness and shortness of breath, which can point to more critical conditions demanding prompt medical attention.
