Which condition is characterized by excessive salivation and choking while feeding?

The condition characterized by excessive salivation and choking while feeding is indeed tracheoesophageal fistula. This congenital condition involves an abnormal connection between the esophagus and the trachea, which can lead to complications during feeding. When a baby attempts to feed, the excess saliva can pool, and if the food or liquid enters the trachea instead of the esophagus due to this abnormal connection, it can cause choking and aspiration.

In contrast, conditions such as pneumonia typically present with respiratory symptoms rather than feeding difficulties. Airway obstruction can lead to choking, but it does not specifically correlate with excessive salivation as a primary symptom. Meconium aspiration syndrome involves the inhalation of meconium into the lungs and is more associated with respiratory distress rather than excessive salivation or choking during feeding. Thus, tracheoesophageal fistula stands out as the condition that matches the specific symptoms described in the question.
