A mother and her 3-year-old daughter come to your office for a well child visit.
Overall, the child seems very healthy, however, during your review of systems, her
mother mentions that the child seems to catch colds very easily. Whenever someone
around her is sick, she becomes symptomatic as well. In fact, it seems as though she has a
runny nose pretty much all of the time. On further questioning, the mother reveals that
her daughter snores at night, takes frequent naps during the day, and has developed
progressively worsening dark circles under her eyes.
