What is "colic"?
I don't know if anybody knows what colic is. But I think colic can basically be described as this indistinguishable, incontrollable fussiness that happens anywhere around two to three weeks of age until about three months. They say colic is the rule of three, so it starts at about three weeks, it ends around three months, and I think the only good thing we can say about it is it does have a definitive ending. It happens at least three times a week where you have a really inconsolably crying baby for sometimes upwards of three hours a night. And we don't know exactly what causes colic. There have been a lot of hypotheses, people thought it was gas, something wrong with the intestinal tract, things to do with being born too early, but we really don't have a cause that fits every child that has colic.
