The exact cause of colic is not known. It is possible that some foods may affect breast milk and contribute to intestinal gas or other digestive problems, which may make crying episodes worse. More research is needed to investigate this relationship.
Foods commonly linked with affecting a mother's breast milk in this way include:
Garlic, onions, cabbage, turnips, broccoli, and beans.
Apricots, rhubarb, prunes, melons, peaches, and other fresh fruits.
Cow's milk.
Caffeine.
If you suspect that your baby's crying becomes worse after feeding with breast milk, keep a record of what you eat and how your baby acts, especially when crying episodes occur.
