Although colic has been studied by many medical experts, there is not yet an
agreement on what it is. One definition is more than 3 hours of crying a day, more than
3 days a week, for more than 3 weeks starting before 3 months of age in an otherwise
healthy and well-fed infant. Colicky babies are also always content at some times every day.
Although there are lots of different ideas about the causes for colic, we do know that parents
are usually not to blame. Colic is rarely caused by a physical illness unless there are other
signs like vomiting, diarrhea, fever, or rash. Call your doctor if these are present or if
your baby isn't happy at any time during the day.
Colic usually begins before three weeks of age. Your baby may be affected by colic
whether you breast-feed or bottle-feed. Anywhere from 7 to 25 percent of all babies get colic
and there are no differences between boys and girls. Colic usually ends when the baby is three
to four months old. Having colic does not mean your baby will grow up to be cranky or to have
anything wrong with them.
