The digestive system creates gas in every one of us, and unlike babies, adults are more polite in passing gas. Trapped gas can cause discomfort in babies that can lead to crying sessions. You may want to check your diet and how you are feeding your little one. A lactation specialist will be able to advise you on other ways to feed your baby. As far as your diet is concerned, gas is a by-product of the digestive system and will always be present. Try limiting "high gas-producing foods" like cabbage and beans but do not totally eliminate them from your diet as they provide essential nutrients.
