Cough in a 2-yr-old Boy

History of Present Illness

A 2-yr-old boy is brought to the emergency department by his parents because of a 1-day history of cough and difficulty breathing. The parents state that the boy appeared normal until the previous night when he began coughing shortly after dinner. The cough stopped after about an hour; the child felt better and went to bed. In the morning, the cough returned and he began to have difficulty breathing, which the parents think is worsening. No one else at home is ill.
