Since the jury is still out on what exactly causes colic, it can be difficult to find a solution. However, formulas that are specifically designed for easier digestion can be of great help and are certainly worth a try. Many people find that switching to a partially hydrolyzed infant formula works surprisingly well. Lactose-reduced formulas may help reduce painful gas caused by lactose sensitivities, and whey-dominant formulas can be easier to digest. Although there are a number of options to try if you suspect that your baby's colic is linked to gastrointestinal discomfort, you should always consult a doctor beforehand.
