Can you sleep train a baby with reflux?

The short answer is, YES! In fact, sleep training often HELPS reflux babies.

Many of the families I am working with at this moment are navigating the challenge of a baby/child with reflux.  Helping parents sleep train a baby who suffers from reflux is one the most common and complex concerns I encounter.  Infant reflux, when stomach contents flow back into the esophagus, can make sleep training feel not only daunting but emotionally exhausting. While all babies have their own unique sleep personalities, reflux adds a layer of discomfort and unpredictability that often leaves parents wondering if sleep training is even possible.

Let me assure you: it is possible. Not only that, but sleeping well often alleviates many of the reflux symptoms. But it does requires patience, flexibility, and a gentle, informed approach.

Understanding Reflux and Its Impact on Sleep

Reflux can cause a range of symptoms from mild spit-up to painful acid reflux (GERD). Babies with reflux often:

• Wake frequently due to discomfort

• Struggle to settle lying flat

• Prefer to be held upright to sleep

• Associate feeding with pain, leading to disrupted feeding and sleep patterns

When sleep becomes associated with discomfort, babies may resist it altogether. That’s where many parents hit a wall. They want to help their baby sleep better, but don’t want to push through pain or distress. It can be so difficult, especially in new little babies, to be able to differentiate their cries. 

The Emotional Toll on Parents

Sleep training is never purely about logistics. It’s deeply emotional. Parents of reflux babies are often second-guessing themselves:

• Is my baby crying because they’re overtired or in pain?

• Am I being too strict—or not consistent enough?

• Is it safe to sleep train right now?

These questions are valid. And the emotional labor of parenting a baby with reflux, especially during sleepless nights, is significant. And since babies can’t talk, it is hard to know exactly what is wrong and in many cases a reflux diagnosis is not made until the baby and parents have suffered for quite a while.

Tips for Sleep Training a Baby with Reflux

1. Get Medical Support First

Before beginning any sleep training, work with your pediatrician or a pediatric gastroenterologist to ensure your baby’s reflux is managed. This might include:

• Thickening feeds (under guidance)

• Trying hypoallergenic formulas or a dairy-free diet for breastfeeding moms (I’ve been here)

• Medication for acid suppression in more severe cases

Without proper management, no sleep strategy will be effective—or fair to your baby.

2. Follow Eat-Play-Sleep

Sounds easier than it is, trust me. But, ESPECIALLY for reflux babies, this is KEY. All babies need time for their stomach contents to digest a bit and for gravity to do the work there if the body won’t naturally do it. This is why it is recommended to hold your baby up-right after feedings. 

The (understandable) trap parents of reflux babies fall into is that many reflux babies fall asleep while eating (for a number of reasons including splitting feeds) and if you have to hold them for 20-30 minutes after eating then you are holding them through their nap or the first part of their night. 

HOWEVER, having worked with so many reflux babies, I will say that once sleep hygiene is cleaned up and your baby is on a daily routine and not being fed to sleep, your child’s reflux WILL dramatically improve AND you don’t have to worry about holding them upright because that is already built into your day. WIN WIN!

3. Smaller, more frequent feeds

For some babies, feeding twice during their awake time may help them with the reflux. This approach can reduce the stomach and esophageal sphincter’s overwhelm and help keep food in the stomach. Be strategic and intentional on this and don’t feed within 30 minutes of your baby’s nap time (or run the risk of feeding to sleep and getting trapped).

4. Watch for Sleep Training Readiness

Your baby needs to be developmentally and physically ready to sleep train. Typically, sleep training is most effective between 4–6 months (although can happen earlier) but reflux can delay readiness. Make sure reflux symptoms are stable before beginning any program.

5. Consistency With Compassion

Consistency builds trust, but with a reflux baby, you may need to modify expectations and pace. It's okay to slow things down if your baby is struggling. Be flexible without losing the overall structure.

What Success Looks Like

Success won’t always be linear. There may be setbacks during illness, developmental leaps, or reflux flare-ups. But over time, even reflux babies can learn to fall asleep independently and enjoy longer stretches of restful sleep.

I’ve seen countless families come out the other side of reflux largely due to getting your baby to sleep well. With the right tools and support, you can help your baby learn to sleep better, even with reflux in the mix.
