Increased fluid retention is indeed a key symptom of congestive heart failure in children. This condition occurs when the heart struggles to pump blood effectively, leading to a backup of fluid in the body's tissues and cavities. This manifests as swelling, particularly in the legs and abdomen, and can also lead to pulmonary congestion, which may present as difficulty breathing or a persistent cough. The body’s attempt to compensate for reduced heart function can result in an imbalance in fluid regulation, highlighting fluid retention as a prominent symptom.

In contrast, flushed skin may indicate different underlying issues but is not a direct symptom of heart failure. High energy levels typically do not correlate with congestive heart failure; in fact, children with this condition might exhibit decreased activity due to fatigue. Frequent urination can occur in conjunction with some heart issues but is not a primary symptom of congestive heart failure, particularly when fluid retention is such a significant concern.
