Colic in babies is a common issue that usually occurs between 3 and 6 weeks and resolves by around 3-4 months of age. Before trying any medication, it is recommended to try natural measures such as massaging the baby's belly, doing "bicycle" movements with their legs, rocking or carrying the baby, having skin-to-skin contact, giving them a warm bath, or taking them for a drive. If there are no improvements after trying these measures for at least a week, it may be necessary to consult a doctor, especially if the baby shows signs such as fever, projectile vomiting, changes in stools or urine, dehydration, lack of weight gain, or persistent irritability.
