What Causes Reflux in Babies?
Infant reflux occurs when milk flows back up from the stomach into the oesophagus.
This happens because babies have:
- immature digestive systems
- a developing lower oesophageal sphincter
- limited time spent upright
Research shows that reflux is very common in infants, particularly during the first few months of life.
Typical symptoms may include:
- frequent spit-up
- discomfort during or after feeding
- unsettled sleep
- crying during feeds
For some babies, reflux can make feeding time uncomfortable, which may lead to feeding difficulties.
How Colic Can Affect Feeding Babies
Colic is typically defined as prolonged periods of crying in otherwise healthy infants.
Colic is often caused by reflux as the milk travelling up and down the esophagus carried air with it which subsequently moves becomes trapped gas. Also discomfort during feeds means babies swallow more air.
Babies with colic may appear hungry but struggle to settle during feeds, which can make feeding babies with colic particularly challenging for parents.
Why Some Babies Struggle to Feed
When a baby experiences reflux or digestive discomfort, feeding may become associated with discomfort.
As a result, some babies may:
- pull away during feeding
- cry while feeding
- feed in shorter bursts
- swallow air during feeds
Parents who are struggling to feed their baby often worry that something is wrong, but many feeding challenges are related to the normal development of the digestive system.
With the right support and environment, feeding can gradually become easier.
The Importance of Position When Feeding a Reflux Baby
Positioning can play an important role in supporting babies with reflux during feeds.
Healthcare professionals often recommend holding babies upright after feeding which allows gravity to help keep milk in the stomach.
Keeping a baby upright after feeding may:
- reduce reflux episodes
- improve digestion
- reduce swallowed air
- make feeding more comfortable
Maintaining a supportive and stable feeding position can also help parents feel more relaxed during feeds.
This is where supportive tools such as a BabyUp®can help parents maintain an elevated and comfortable position post feeds whilst still managing to go about their day and allows the baby to rest comfortably.
Simple Ways to Make Feeding Time Calmer
Small adjustments can often make a big difference when feeding babies with reflux or colic.
Helpful strategies include:
Feeding slowly and responsively
Watch your baby’s cues and allow pauses for burping.
Creating a calm environment
Reducing noise and stimulation can help babies stay relaxed during feeding.
Offering smaller, more frequent feeds
This can reduce stomach pressure and help babies digest milk more comfortably. Although if breastfeeding it is important to feed long enough for the infant to reach the denser more fatty milk. A technique may be to use the same breast for two smaller feeds.
Keeping babies upright after feeds
Holding babies upright for 20–30 minutes after feeding may help reduce reflux; the BabyUp® helps sustain this and allow for comfort.

Weaning a Reflux Baby
Many parents wonder whether starting solids may help with reflux.
When weaning a reflux baby, healthcare professionals often suggest:
- waiting until developmental readiness signs appear
- introducing simple foods gradually
- keeping babies upright during and after meals and supporting feet positioning to not cause extra strain on the stomach
For some babies, reflux improves as their digestive system matures and solid foods are introduced.
However, parents should always consult a healthcare professional if they have concerns about feeding or reflux symptoms.
Supporting Parents Through Feeding Challenges
Caring for a baby with reflux or colic can be emotionally demanding. Many parents feel discouraged when feeding becomes difficult.
It is important to remember:
- reflux is common in infants
- feeding challenges are often temporary
- support and positioning can help improve feeding comfort
With time, patience, and supportive feeding practices, many babies grow out of reflux and feeding difficulties.
Creating Calmer Feeding Moments
While reflux and colic can make feeding babies more challenging, many simple strategies can help support calmer feeding experiences.
By focusing on:
- responsive infant feeding
- calm environments
- Keeping the infant upright post feed
Parents can help transform feeding time from a stressful experience into a more comfortable and connected moment.
