Colic
Key Points
Colic is excessive crying for no discernible reason in an otherwise healthy infant. Colic typically ends by age 3 to 4 months. Rule out medical causes of crying by history and physical examination; testing is unnecessary unless there are specific findings. Physical measures (eg, rocking, swinging, swaddling) can be tried, as may dietary changes; response to these measures varies, and usually colic resolves only with time.
