Infantile colic is a condition that affects more than 10% of babies and their families. The reason, and hence the proper treatment, for this condition is unknown and many causes have been suggested. One of the treatments that parents choose is chiropractic manipulation. In Denmark, around 4,000 babies are treated for colic by chiropractors each year although the effect of chiropractic treatment of infantile colic has not been properly scientifically evaluated.
