Best Sleeping Position for Acid Reflux: Adults vs. Babies

If you have acid reflux at night, sleeping on your left side is generally a better choice than sleeping on your right side or flat on your back, because it can make it harder for stomach contents to move up into the esophagus. You can also raise your upper body with a wedge pillow or by elevating the head of your bed; stacking ordinary pillows under your head alone may bend your neck without lifting your torso.

Check the product’s listed specifications when evaluating for adults, start on your left side.

Try to finish eating at least two to three hours before bed, especially if reflux tends to wake you after a late dinner. A smaller evening meal may also be more comfortable than a large one, and noticing which foods or drinks trigger your symptoms can help you decide what to avoid close to bedtime.

If your question is about a baby with reflux, the answer is different: place your baby on their back for every sleep, on a firm, flat sleep surface without wedges, positioners, or pillows. Side sleeping, stomach sleeping, and inclined sleepers are not recommended as reflux fixes for infants, even when an adult finds a different position helpful.

Check the product’s listed specifications when evaluating for babies, safe sleep comes first.

While your baby is awake and supervised, you can hold them upright during and after a feeding, burp them as needed, and talk with their pediatrician if spit-up or discomfort is frequent. When it is time to sleep, return your baby to their back on the flat sleep surface rather than trying to keep them propped up.

Check the product’s listed specifications when evaluating support comfort before putting your baby down.

If your own reflux regularly disrupts sleep despite changing your position and meal timing, ask a healthcare professional about treatment rather than relying on positioning alone.
