There seems to be no link between colic and the sex of the child, the birth order or intelligence, and it does not run in families. There is nothing to indicate that a baby with colic will turn out to be a difficult child later in life. That does not mean it's easy to deal with. But there are a number of techniques that seem to help. One of the most effective is movement.
Some babies like to be carried in a sling or a pack, others prefer the rocking motion of a cradle.
One Alberta study showed that the most effective rhythm is one rocking move-ment per second, but see what works best with your child. Taking the baby for an outing in a baby carriage or stroller may also help. White noise, an electronic noise with a constant intensity, is also very effective even a dishwasher or vacuum cleaner can lull the baby to sleep. Try combining motion and white noise by carrying the baby in a pack while you're vacuuming. One father while holding his crying baby, found that the noise of the aerator on a nearby fish tank soothed the baby.
