Colic is a condition in which a healthy baby experiences repeated bouts of intense crying for no clear reason. It is commonly defined as crying for more than 3 hours a day, for more than 3 days a week, and for at least 3 weeks, usually starting when the baby is a few weeks old and typically resolving by 3 to 4 months of age. During colic episodes, the baby may be difficult to soothe, cry with a high-pitched sound, pull up their knees, arch their back, clench their fists, and may have a red face or abdominal rumbling. Despite the distressing crying spells, babies with colic are otherwise healthy, feeding well, and growing normally. The exact cause of colic is unknown, but it may be related to digestive discomfort, hormonal changes, or gut bacterial imbalances. There is no specific treatment for colic, and it usually resolves on its own over time. Parents can try various soothing techniques to help manage colic and should consult a healthcare provider if they have concerns about the baby's health.
