Beyond infant colic.

Some of the most interesting cases in pediatric practice evolve through time. What may begin as a clear, well defined problem with a predictable natural history and an accepted intervention strategy may develop into a more complex, multi-faceted set of problems. It is these children who potentially provide clinicians with new insights into behaviors. This case of a colicky infant illustrates the wide spectrum of behavioral and physiological symptoms that emerge from a specific underlying behavioral phenomenon. It also emphasizes the significant benefit derived from a longitudinal perspective of developmental events.
