Common Indicators of Acid Reflux in Babies
This article highlights the key symptoms of acid reflux in infants, including spitting, feeding difficulties, coughing, and sleep issues. Understanding these signs can help parents seek timely medical care for their babies. Acid reflux often occurs in infants due to an underdeveloped LES and tends to improve around 12 to 18 months. Recognizing symptoms early ensures appropriate management and relief for affected children.

Signs of Acid Reflux in Infants
Acid reflux occurs when stomach acid flows back into the esophagus, leading to discomfort and a burning sensation often called heartburn. If an infant experiences this twice weekly, it may indicate gastroesophageal reflux disease (GERD).
Young children are especially vulnerable due to a less mature lower esophageal sphincter (LES), the muscular ring connecting the stomach and esophagus.

- Spitting up or vomiting
- Eating difficulties
- Hiccups and wet burps
- Weight loss or poor growth
- Unusual body arching
- Frequent coughing or lung infections
- Sleep disturbances
Normal spitting is common, but forceful vomiting or spitting blood or green-yellow fluids warrants concern.
Refusal to feed or discomfort during eating may indicate reflux when stomach contents irritate the esophagus.
Frequent hiccups or liquid during burps can be symptoms, though less common.
Significant vomiting can prevent weight gain, signaling possible reflux issues.
Persistent arching may signal pain from acid exposure, but could also stem from other causes.
Chronic cough or pneumonia might develop if reflux leads to inhaled stomach contents or triggers airway inflammation.
Difficulty sleeping through the night is common if reflux irritates the throat—feeding earlier before bedtime might help.
