Reflux and Sleep Positioning
The short answer
Despite what seems intuitive, the AAP recommends that all babies, including those with reflux, sleep flat on their backs on a firm surface. Elevating the head of the crib and sleep positioners are NOT recommended as they have not been shown to reduce reflux and may increase the risk of SIDS or suffocation. Babies have protective reflexes that prevent aspiration during sleep.
Parents everywhere have the same worry. You are doing the right thing by looking into it.
By Age
What to expect by age
Always place your baby on their back to sleep on a firm, flat surface, even with reflux. Do not use crib wedges, pillows, or sleep positioners. These products are not safe and the FDA has warned against them. If you are worried about spit-up during sleep, know that healthy babies have reflexes to turn their head and clear their airway.
Continue safe sleep practices. Keeping baby upright for 20 to 30 minutes after feeds before laying down can help reduce reflux episodes during sleep. Avoid feeding right before bedtime if reflux is problematic at night. A consistent bedtime routine with a feed earlier in the sequence may help.
As reflux improves and babies begin to roll, sleep becomes less of a concern. Once a baby can roll both ways independently, they can be left in whatever position they roll to. Continue starting them on their back. Nighttime reflux typically improves as solids are introduced.
By this age, sleep positioning for reflux is rarely a concern. If your toddler continues to have nighttime reflux symptoms, avoid large meals and acidic foods close to bedtime. Raising the head of the bed slightly (by putting books under the crib legs, not using a pillow) may be discussed with your pediatrician.
What Should You Do?
When to take action
- A baby with reflux who sleeps safely on their back and has occasional spit-up that does not cause distress
- Brief gagging or coughing that the baby clears on their own during sleep
- Reflux is significantly disrupting your baby's sleep and you need strategies
- You are worried about your baby choking on spit-up during sleep
- You want guidance on the safest sleep setup for a baby with reflux
- Your baby has had an apparent life-threatening event with apnea, color change, or limpness during or after sleep
- Your baby is regularly choking or gagging severely during sleep, not just minor spit-up

Related Digestive Concerns
Baby Reflux / GERD
Gastroesophageal reflux is very common in babies because the valve at the top of the stomach is still maturing. Most infant reflux is uncomplicated, meaning your baby spits up but is otherwise happy and growing well. True GERD, where reflux causes pain, feeding difficulties, or poor weight gain, affects a smaller number of babies and is very treatable.
Baby Spitting Up Frequently
Spitting up is extremely common in healthy babies and is rarely a sign of anything serious. About half of all babies spit up regularly in the first few months, peaking around 4 months and typically resolving by 12 months. If your baby is gaining weight well, seems comfortable, and is a "happy spitter," the spit-up is usually more of a laundry problem than a medical one.
Silent Reflux in Baby
Silent reflux occurs when stomach acid rises into the esophagus and throat but is swallowed back down rather than spit up. Babies with silent reflux may be fussy during or after feeds, arch their back, have hoarse crying, or refuse to eat, but without visible spitting up. It can be harder to diagnose than typical reflux because there is no obvious spit-up.
My Baby's Belly Looks Swollen
A rounded, slightly protruding belly is completely normal in babies and toddlers due to immature abdominal muscles and their proportionally larger organs. However, if the belly becomes suddenly swollen, feels hard and tight, or is accompanied by pain, vomiting, or changes in bowel movements, it needs medical evaluation as it could signal gas buildup, constipation, or rarely, something more serious.
My Baby Has an Anal Fissure (Blood When Pooping)
A small streak of bright red blood on the surface of your baby's stool or on the diaper is most commonly caused by an anal fissure, which is a tiny tear in the skin around the anus from passing hard stool. Anal fissures are very common in babies and toddlers and usually heal on their own with simple measures like keeping stools soft. While this is rarely serious, any blood in your baby's stool should be mentioned to your pediatrician.
Tummy Massage for Baby Gas
Gentle abdominal massage can help relieve gas and discomfort in babies by encouraging gas to move through the intestines. The technique involves gentle clockwise circular motions on the belly (following the direction of the digestive tract), the "I Love U" stroke pattern, and gentle knee-to-tummy movements. Massage also provides comforting touch that can soothe a fussy baby.
