Babies may vomit while passing gas because gas pushes the mixture of food and air in the stomach upward. Especially in the early months, the valve between baby's stomach and food pipe (lower esophageal sphincter) isn't fully developed, so when abdominal pressure increases — like when passing gas — stomach contents can escape upward.
Additional factors:
- If baby is straining while passing gas and tightening belly muscles, this squeezes the stomach, triggering vomiting.
- If baby passes gas shortly after eating, pressure changes while stomach is full can trigger vomiting.
If the amount is small and baby seems comfortable, this is usually normal (called regurgitation). However, if vomiting is frequent or large in amount, baby isn't gaining weight, or there's bile (green/yellow) or blood in the vomit, you should consult a pediatrician.
