🤮 Acid Reflux or Just Normal Spit-Up?

All babies spit up: the little valve at the top of their stomach isn't quite up to speed yet. You just need to tell the difference between a harmless 'happy spitter' and actual reflux—painful acid that burns their little food pipe and makes life miserable.

Telling the Difference

  • Normal spit-up: Milk comes up effortlessly after a feed, baby doesn't cry, gains weight normally, and smiles through it all. Only your clean t-shirts suffer.
  • Acid reflux (GERD): Intense crying during or after feeds, baby arches their back, makes chewing motions between feeds, hates lying flat, and sleeps terribly.
  • Silent reflux: Baby doesn't actually spit anything up, but you can hear the liquid rising and they gulp it back down while wincing or crying.

Anti-Reflux Tactics

  1. 1. Keep 'em upright

    Keep baby upright against your chest or in a sling for 20 to 30 minutes after every feed.

  2. 2. Burp breaks

    Take regular burping pauses during feeds to let out trapped air before it turns into a geyser.

  3. 3. Nothing tight on the tummy

    Keep the nappy loose around the waist and ditch pants with tight elastic bands.

  4. 4. Elevating the mattress: doctor's orders only

    A certified wedge (15°) under the fitted sheet should only be used if recommended by a doctor. Never improvise with pillows or rolled-up towels.

  5. 5. When to call the doctor

    If baby's weight plateaued, they refuse feeds, or you spot blood in the spit-up, get them checked by a doctor right away. They might suggest thickened formula or prescribe medication.

  6. 6. Dad hack

    A baby carrier is your secret weapon against reflux: it keeps baby perfectly upright after eating, your body heat soothes their belly, and you actually get your hands back.
