What causes spitting up?
Spitting up is common in healthy babies. During their first three months, about half of all babies experience their stomach contents coming back up into the esophagus, a condition known as gastroesophageal reflux, infant reflux or infant acid reflux.
Normally, a muscle between the esophagus and the stomach (lower esophageal sphincter) keeps stomach contents where they belong. Until this muscle has time to mature, spitting up might be an issue — especially if your baby is relatively full.
