Some substances in the formula and breast milk may be hard for infants to digest, resulting in excess gas. For example, if you consume cow’s milk or use a formula that contains cow’s milk proteins, your baby may have trouble digesting the some of the substances they ingest. Other foods (often the same ones that cause gas in adults) can also pass along nutrients in breast milk that are difficult to digest, like broccoli, cabbage, and spicy foods. If your infant seems to be especially gassy, consider discussing changes to your diet or an alternative formula with your child’s pediatrician.
