Colic is defined by Stedman's Medical Dictionary as "Spasmodic pains in the abdomen. In young infants, paroxysms of gastrointestinal pain, with crying and irritability"

Chiropractic: An effective "treatment" for colic:
1.
A recent Danish Study showed that of 316 infants with colic, 94% responded to chiropractic care. The researchers concluded that spinal manipulation "constitutes an effective treatment of the condition"
Reference: Klougart, et al. Infantile Colic Treated by Chiropractors: A Prospective Study of 316 Cases. Journal of Manipulative and Physiological Therapeutics, 1989).
2.
In yet another study, involving 132 infants with colic, 91% of parents reported improvement after chiropractic care.
Reference: Nilsson N. Infant colic and chiropractic. Eur J Chiropr 1985;33(4): 264-5.
3. NEW STUDY...
A most recent study divided 50 infants with colic into two groups. The first group received chiropractic for two weeks; the second group received traditional drug treatment (dimethicone) over the same two weeks.
Results revealed that the chiropractic group improved more than the drug group (less hours spent crying) after the first five days of the study. After day five, the dimethicone group showed little or no reduction in average colic hours per day. Specifically,
* Days 4-7: Hours of crying were reduced by a total of 2.4 hours in the chiropractic group compared with only one hour in the drug group.
* Days 8-11: Hours of crying were reduced by 2.7 total hours in the chiropractic group, compared with one hour in the drug group.
 
Important to note that five infants in the dimethicone group dropped out before the end of the study, described by their patients as having "worsened" or "much worsened" colic.
The authors suggest that if these severe cases had been included in the results, the drug intervention would have appeared even less effective than chiropractic for reducing the symptoms of colic.

Comment:
Perhaps the success of chiropractic in something like the above may be explained by the spinal nerve connections to all organs of the body, as mentioned in this scientific paper which states
there is a "connection between the abdominal pain and back troubles", and "...stimulation of receptors in some ... areas of the viscera (organs)might, via ... nerves to the spinal cord, (cause) alterations of skin sensibility, segmental spinal tenderness, & fixation of vertebrae." (Jorgensen et al. Scand J of Gastroenterology, 25, 1990)

It seems worthwhile that children suffering from colic should have chiropractic as an option, and have spinal problems ruled out. What's more, It is a drug free, safe approach.
