Colic is so general among infants that most individuals are not surprise any longer when it occurs. Still, for the first time mother it may be a harrowing and panicking experience particularly with her normally quiet angel screaming around-the-clock in the background. It's commonly manifested at about 2 to 3 weeks of age. It gets more prominent during the first 2 months and subsides at 3 months old. Colic totally stops at about three-and-a-half to four months of age.
