Baby Reflux

Spitting up after feeds is extremely common in babies — over 50% spit up regularly. The sphincter between stomach and oesophagus is still immature. It's usually harmless ('happy spitter').

Possible Causes

  • 1Immature lower oesophageal sphincter
  • 2Liquid diet and lying position
  • 3Drinking too fast or swallowing air
  • 4Cow's milk protein intolerance (in severe reflux)
  • 5Pyloric stenosis (severe projectile vomiting weeks 2-8)

What You Can Do

  • Hold upright: 20-30 minutes after feeding
  • More frequent, smaller feeds
  • Burping — regularly during and after feeds
  • Elevate upper body slightly (wedge under mattress)
  • Anti-reflux formula (AR) for bottle-fed babies — on medical advice

When to See a Doctor

  • Baby cries during/after feeds (painful reflux)
  • Baby not gaining weight adequately
  • Food refusal
  • Breathing pauses or coughing when spitting up
  • Greenish vomiting (bile → EMERGENCY)

Age-Specific Notes

Reflux usually starts in the first weeks, peaks at 4-5 months, and improves significantly from 6 months (when baby can sit). 95% of babies have no more reflux by 12 months.

Frequently Asked Questions

When is reflux dangerous?
When your baby cries while spitting up (pain), isn't gaining weight, refuses food, or has breathing problems. This is called GERD and needs medical treatment.
Should I thicken the milk?
For bottle-fed babies, AR formula (anti-reflux) can help — it's thicker and stays in the stomach better. But ONLY after consulting the paediatrician. Breast milk should NOT be thickened.
