Gas in newborn infants can be a terrific concern to the parent.
Gas can seem a significant cause of discomfort to the infant.
Except for the latter case, there is no cause for concern if the infant does not seem to be bothered by the gas. As for milk intolerance, this is usually associated with diarrhea, vomiting or poor feeding, so gassiness is usually the least of worries in that case. The introduction of air into the intestines must by definition be preceded by the introduction of air into the stomach. In either case, frequent burping say once between each ounce for bottle feeders, or twice per breast for breastfeeders will help eliminate much of the air that made it to the stomach. Finally, there is a medication that is supposed to help eliminate gas from the intestines.
