Reflux & Baby Sleep
I’ve been there, mama. Both of my kids had BAD reflux, and sleep was always affected. If you’ve been around for a while, I’m sure you’ve heard the phrase “rule out reflux.” It’s a hot topic because reflux impacts many newborns yet can be tricky to identify.
It can be SO frustrating when you’re doing everything right—following sleepy cues and age-appropriate wake windows—but your baby is still extra fussy. If this sounds familiar, tummy troubles like reflux might be the culprit. Remember, it’s not your fault, and seeking help is the best thing you can do for your baby.
What is Reflux?
Think of reflux as similar to pregnancy heartburn. If you experienced that, you know how awful it can feel. It keeps you from resting, making lying flat, uncomfortable and nauseous. This is similar to what your little one feels with reflux.
Two main factors contribute to reflux in babies:
Overproduction of Stomach Acid
You may have heard the term “happy spitter.” Some babies spit up a lot without any discomfort or sleep issues. But when reflux is due to excess stomach acid, spit-up burns on its way out, making it very uncomfortable.A Weak Esophageal Sphincter
The esophageal sphincter is a small muscle that keeps food from coming back up. Because babies are so tiny, this muscle isn’t always strong enough, leading to frequent spit-ups.
Reflux itself isn’t necessarily bad—most babies experience it. The main concern is whether it’s painful, which helps determine if treatment is needed.
Signs That Your Baby Might Have Reflux
Frequent swallowing or gargling sounds
Excessive spit-up (more than 15-30 ml each time)
Spit-up coming out of the nose
Screaming and back-arching
Tummy troubles, including gas
Difficulty maintaining weight or weight loss
Additional Signs
Sour breath or smelly spit-up
More comfortable when upright and upset when lying down
Curdled spit-up (like cottage cheese)
Most fussy right after feeding
Frequently pulling off the breast or being unhappy while nursing
How Does Reflux Affect My Baby’s Sleep?
Reflux makes the newborn stage even more challenging. It’s heartbreaking to see your baby in pain, especially during feeding and sleep times when they should be most comfortable.
If reflux affects feeding, your baby may only get enough to satisfy hunger but not enough for a full, restful feed. As a result, they may wake up more frequently at night to eat.
What Can I Do to Help My Baby?
Burp your baby frequently between breasts or after every ounce.
Do extra burping after each feed.
Offer smaller, more frequent feedings.
Try paced bottle feeding (mimics breastfeeding).
Keep your baby upright for more extended periods, especially during the day.
Consider cutting out dairy or other potentially sensitive foods.
Most infants outgrow reflux between 6-12 months. If you’re concerned about your baby’s reflux, talk to your healthcare provider to discuss potential medications, food intolerances, or other health concerns.
