To help with reflux in babies, it is best to know what it is. Reflux is a backward flow of the contents of the stomach into the esophagus that causes heartburn.
Reflux is one of the most common conditions newborns face and is often caused by the esophageal sphincter valve not being fully developed. This causes milk to come back up the esophagus through the throat and causes baby to spit up and vomit. Reflux can be upsetting, alarming, and painful to babies. When the contents of the stomach come back up, it is usually mixed with some stomach acid, which creates a burning sensation.
