What can one do to calm colic in a baby?

Unfortunately the only "cure" for colic is time. Babies usually outgrow the worst symptoms of colic by 4-6 months. In the meantime there are several things one can do to make the baby as comfortable as possible. Rubbing their stomach and left side in a clockwise circle can help with digestion. Bicycling their legs can help relieve gas. Sometimes a warm bath can soothe an upset baby. Some mothers swear by gripe water or other colic medicines, but there isn't much scientific proof to back up these claims.
