Infant colic is a common condition in babies, typically defined as excessive crying for more than three hours a day, three days a week, for three weeks or longer. It usually starts when a baby is a few weeks old and can last until they are about three to four months old. The exact cause of colic is not well understood, but it may be related to factors like digestive issues, sensitivity to stimulation, or an immature nervous system. Parents often find it challenging to soothe a colicky baby, leading to stress and frustration. While colic is not harmful to the baby, it can be distressing for both the infant and caregivers. Various strategies, such as holding the baby, using gentle rocking, or playing white noise, may help alleviate symptoms.
