Quick Answer

Spit-up is common in young babies due to an immature digestive system and air swallowing. You can reduce it by adjusting feeding position, pacing feeds, and using an anti-colic bottle like Dr. Brown's Natural Flow Options+ Wide-Neck Bottle.

Why Spit-Up Happens (and When to Worry)

Spit-up (reflux) is normal for most babies under 6 months because the muscle between the stomach and esophagus is still developing. It's different from forceful vomiting, which may signal illness. Occasional spit-up is not a cause for alarm, but if your baby is not gaining weight or seems uncomfortable, consult your pediatrician.

Air swallowed during feeding is a major contributor. A fast milk flow, a poor latch, or crying before a feed can all increase air intake, leading to more spit-up later.

Feeding Position Matters More Than You Think

Hold your baby in a semi-upright position during feeds, not lying flat. Gravity helps milk stay down. After feeding, keep your baby upright for 20–30 minutes to allow the milk to settle. Avoid bouncing or active play right after a feed.

Diagnosis: Is Your Baby's Spit-Up Normal?

  • Symptom: Baby spits up small amounts of milk (like curdled milk or clear liquid) during or within 30 minutes of a feed. Baby seems content afterward.
  • Likely Cause: Immature digestive valve (lower esophageal sphincter) plus swallowed air from fast flow, poor latch, or a bottle that doesn't vent air well.
  • Corrective Action: Feed in a semi-upright position, use a slow-flow nipple (Level 1), burp every 1–2 ounces, and consider a vented bottle like Dr. Brown's Natural Flow Options+ to reduce air intake. If spit-up continues after 2 weeks of these changes, check with your pediatrician to rule out GERD or allergy.
  • When to Stop or Choose Another Option: If baby spits up forcefully, loses weight, or has blood in spit-up, stop home remedies and see a doctor. For persistent mild spit-up, a thicker formula (if advised by your pediatrician) or a different nipple flow may help.
