Colic occurs at least 3 days a week and often, none of what parents do seems to help them feel better. It is certain that colic in infants is annoying for both parents and babies, but we must always keep in mind that their duration is very short. They usually appear at 3 to 6 weeks of age and subside in the fourth month of life. It is important for parents to know everything about colic as the intense crying of babies has many effects on the psychology of the parents and especially on the mother, where it can be a cause for possible postpartum depression.
