What is regurgitation?

Regurgitation, also known as spitting up or posseting, is very common in infants and often occurs after feeding. It involves the mild vomiting or regurgitation of food, milk, and saliva. However, unlike vomiting, there’s no straining involved, and the symptom occurs without nausea.

How do I know if my baby has regurgitation?

An otherwise healthy infant between three weeks and 12 months of age has regurgitation if he or she meets the following criteria:

  • Two or more regurgitations per day for three weeks or more
  • No retching, hematemesis, swallowing or feeding difficulties, abnormal posturing

What causes regurgitation?

Regurgitation occurs when the esophageal sphincter, which prevents food from flowing back up towards the mouth, is not fully formed in infants. Regurgitations gradually disappear during the child’s first year as the digestive tract matures and the child begins to be in an upright position more often.
