Why does my baby have gas?
Gas collects in the stomach and bowels for various reasons. Babies swallow air when they feed, and bacteria in the bowel produce gas when they act on the stool. The resulting gas can stretch the stomach and bowels, causing pain. The gastrocolic reflex, or cramping of the bowels needed to move the gas and stool can produce noise and more pain. In either case, putting the baby against the mother’s upper chest and shoulder and massaging the baby’s back can ease the pain.
