At 18 months, Christian had an illness in which he had a high fever, cough and difficulty breathing. We took him to the emergency room at our local hospital, because we thought his breathing seemed labored. They told us that it was just an upper respiratory infection and his lungs were clear, and to follow up with his pediatrician the next day. The hospital did not perform a chest x-ray at this visit, because a chest x-ray is not considered a part of the standard testing procedure. We followed up with the pediatrician the next day, and the pediatrician agreed that it was just an upper airway illness and gave him antibiotics. The fever and coughing went away, but Christian was never the same. He was irritable, he couldn't sleep, and cried a lot more than before.
