GERD (Reflux) in Babies and Children
Content reviewed against published AAP, AAP, NIH guidelines
Last reviewed:
GERD is a condition where stomach contents frequently flow back into the esophagus, causing troublesome symptoms or complications. While simple reflux (GER) is normal in infants — affecting up to 70% of 4-month-olds — GERD is diagnosed when reflux causes significant symptoms like poor weight gain, feeding refusal, esophagitis, or respiratory problems. Most infant reflux resolves by 12-18 months as the lower esophageal sphincter matures.
Key takeaways
- GERD is a condition where stomach contents frequently flow back into the esophagus, causing troublesome symptoms or complications.
- Duration: Simple infant reflux (GER) typically peaks at 4 months and resolves by 12-18 months in 95% of infants. True GERD requiring treatment may persist longer. If symptoms continue beyond 18 months, further evaluation is warranted. Some children have GERD into childhood or adolescence.
- Go to ER if: Green (bilious) vomiting — may indicate intestinal obstruction
- No vaccine currently available
Symptoms
How It Presents by Age
0-4 months
Spitting up is nearly universal and usually normal ("happy spitter"). GERD is suspected when reflux causes poor weight gain, extreme irritability with feeds, or feeding refusal. Distinguish from pyloric stenosis (projectile, worsening).
Risk level: Low if gaining weight; moderate if symptomatic GERD
4-12 months
Peak of normal reflux at 4 months then gradual improvement. GERD may persist with ongoing feeding difficulties, slow weight gain, and irritability. Introduction of solids and more upright positioning often help.
Risk level: Low to moderate
12-24 months
Most physiological reflux has resolved. Persistent symptoms warrant evaluation for true GERD. May present as food refusal, gagging with textures, or chronic cough. Sandifer syndrome more recognizable at this age.
Risk level: Low
2-5 years
GERD in older children presents more like adults: heartburn, regurgitation, abdominal pain, chronic cough, and dental erosion. May have difficulty expressing symptoms. Consider if recurrent respiratory symptoms without other cause.
Risk level: Low
Treatment
Feeding modifications
First-line management: smaller, more frequent feeds; hold upright for 20-30 minutes after feeding; thicken formula with oat cereal (1 tablespoon per ounce, or use pre-thickened anti-reflux formula). For breastfed babies, a 2-4 week trial of maternal dairy elimination may help if cow milk protein intolerance is suspected.
Positioning
Keep baby upright during and for 30 minutes after feeds. Elevate the head of the crib (place wedge under mattress, not loose pillows). Avoid car seats and bouncy seats immediately after feeding as they increase abdominal pressure.
Acid suppression (H2 blockers)
Famotidine (Pepcid) is sometimes used for moderate symptoms not responding to lifestyle changes. Reduces acid production. Note: reducing acid does not reduce reflux volume, only its acidity.
Proton pump inhibitors (PPIs)
Omeprazole (Prilosec) or lansoprazole for documented esophagitis or severe symptoms. NASPGHAN guidelines recommend against empiric PPI use in "fussy" infants without objective evidence of GERD. PPIs carry risks including increased respiratory and GI infections.
Cow milk protein elimination
Trial of extensively hydrolyzed formula (Alimentum, Nutramigen) or amino acid formula for 2-4 weeks, as up to 40% of infants with GERD symptoms may have underlying cow milk protein intolerance.
Surgical (fundoplication)
Reserved for severe, medication-resistant GERD with life-threatening complications (recurrent aspiration, failure to thrive). Nissen fundoplication wraps the stomach fundus around the esophagus to tighten the LES.
Home Care
- Feed smaller amounts more frequently
- Keep baby upright for 20-30 minutes after each feeding
- Burp frequently during feeds (every 1-2 ounces)
- Avoid tight diapers or clothing around the waist
- Thicken formula with oat cereal if recommended by pediatrician
- Avoid overfeeding — follow baby's hunger and fullness cues
- For breastfed babies: try eliminating dairy from maternal diet for 2-4 weeks
- Allow baby to sleep on their back (tummy sleeping is NOT recommended even with reflux)
- Avoid exposure to tobacco smoke (weakens the LES)
When to Worry
Go to the ER if:
- Green (bilious) vomiting — may indicate intestinal obstruction
- Projectile vomiting worsening over days (possible pyloric stenosis)
- Significant blood in vomit (not just streaks from cracked nipples)
- Signs of severe dehydration
- Apnea or breathing stops after vomiting episode
- Baby is limp or unresponsive after a choking/vomiting episode
- Severe abdominal distension with vomiting
Call your doctor if:
- Baby is not gaining weight appropriately
- Extreme irritability during and after every feed
- Refusing to eat or taking dramatically less than normal
- Frequent vomiting (more than 5 times daily)
- Blood in spit-up or vomit
- Chronic cough or wheezing without other explanation
- Symptoms not improving with 2 weeks of lifestyle modifications
- Signs of pain with swallowing (crying, arching)
Keep an eye on:
- Baby is not gaining weight or losing weight
- Forceful vomiting that is worsening (rule out pyloric stenosis)
- Green (bilious) vomiting (suggests intestinal obstruction — emergency)
- Blood in vomit or stool
- Baby refuses all feedings
- Choking or apnea episodes
- Chronic cough or recurrent pneumonia
Prevention
- Avoid overfeeding — follow hunger/satiety cues
- Feed in upright position and maintain upright posture after feeds
- Burp frequently during feeds
- For formula-fed infants, use properly prepared formula (not over-concentrated)
- Avoid tobacco smoke exposure
- Respond to early feeding cues (prevents gulping from excessive hunger)
- Consider paced bottle feeding to reduce air swallowing
Contagion & Incubation
Incubation
Not applicable. Simple reflux (spitting up) typically begins in the first weeks of life, peaks at 4 months, and resolves by 12-18 months. GERD may be present from birth or develop later.
Contagious for
Not contagious.
Duration
Simple infant reflux (GER) typically peaks at 4 months and resolves by 12-18 months in 95% of infants. True GERD requiring treatment may persist longer. If symptoms continue beyond 18 months, further evaluation is warranted. Some children have GERD into childhood or adolescence.

Bottom line
GERD (Reflux) is treatable with appropriate medical care. Seek emergency care if green (bilious) vomiting — may indicate intestinal obstruction.
Trust your instincts. If something feels wrong, reach out to your pediatrician. Worrying about your baby means you care — that is a good thing.
