Vomiting during or shortly after feeding is a very common condition in babies and often has a physical explanation. In newborns and small babies, the valve between the stomach and esophagus (lower esophageal sphincter) is not yet fully developed, so stomach contents can easily back up. This is called physiological insufficiency, not 'reflux,' and usually resolves on its own between 6-12 months.
Common causes:
- Overfeeding (small stomach capacity)
- Swallowing too much air during feeding (especially in fast-sucking babies)
- Moving or lying down soon after feeding
- Baby's position (feeding too upright or too reclined)
- Bottle nipple size that is too large or too small
In most cases, this type of spitting up is not concerning. If the baby is comfortable, weight gain is normal, and it comes from burping, monitoring is sufficient. However, projectile vomiting (especially in 2-8 week old babies that gradually worsens) or green/bilious vomiting should definitely be evaluated by a pediatrician.
