The great air debate: How different swallowing patterns impact breastfeeding and reflux

The great air debate
As a Speech and Language Therapist specialising in infant feeding, I often hear from worried mums describing their breastfed baby’s fussiness. ‘My baby is so burpy and gassy,’ ‘might it be reflux?’ or ‘she just seems uncomfortable after every feed’. While these concerns are incredibly valid and distressing for both baby and mum (and dads!), the underlying cause isn’t always what you might think. Often, the culprit isn’t primarily a digestive issue, but rather a mechanical one: how effectively your baby is managing air during feeding.
Many parents are told their baby has ‘colic’ or ‘reflux’ and are offered solutions that don’t quite hit the mark because they overlook a fundamental aspect of feeding: the suck-swallow-breathe sequence. Understanding this intricate dance can be the key to unlocking a calmer, happier feeding experience for your baby and you.
Understanding the suck-swallow-breathe sequence
Your baby’s mouth, tongue, jaw, and throat muscles work together in a precise rhythm like a beautifully orchestrated symphony. First your baby draws milk, then swallows it, and then takes a breath, all without interruption. This is the ideal suck-swallow-breathe (SSB) sequence.
When the SSB sequence functions optimally, a baby latches deeply, creates good suction, draws milk, swallows efficiently, and then pauses just long enough to take a gentle breath before the next suck. This smooth, coordinated process minimises the amount of air swallowed.
However, for various reasons (it could be a shallow latch, oral motor challenges, an uncoordinated suck, or even an overly fast milk flow) this sequence can get a bit out of sync. Instead of a smooth rhythm, you might see:
- Suck-suck-swallow-gasp!: Too much air pulled in with the swallow.
- Rapid, shallow sucking followed by gulping: Inefficient milk transfer and air intake.
- Clicking noises during feeding: Loss of suction, indicating air entry.
- Frequent detaching and re-latching: Often to ‘catch a breath’ or because of discomfort.
Each of these patterns can lead to increased air intake.
The root cause: Air trapping leading to a gassy breastfed baby
When a baby swallows too much air during a feed, that air must go somewhere. It builds up in the stomach, causing bloating, discomfort, and often leads to the familiar reflux-like symptoms parents describe: arching, spitting up, burping excessively, or simply appearing distressed.
It’s a common misconception that all gassiness or reflux symptoms in a breastfed baby are due to something in the mother’s diet or a genuine digestive disorder. While these can be factors, as an SLT, we first look at the mechanics of the feed. If a baby is constantly struggling to maintain a seal, sucking inefficiently, or having to gulp to keep up with flow, he or she is inevitably swallowing air. This air then creates pressure, which can push milk back up (silent reflux) or out (visible reflux).
Think of it like trying to drink through a straw with a hole in it. You’re sucking, but you’re also pulling in air, making it harder to get the liquid and leaving you with more bubbles in your stomach.
Why mechanical speech therapy assessment is key
This is where the distinction between a medical diagnosis (true gastro oesophageal reflux disease or GORD) and a functional feeding challenge becomes critical. A paediatrician will assess for medical causes and may prescribe medication to reduce stomach acid. This can be appropriate for severe cases of GORD.
However, if the primary issue is air being trapped due to a suboptimal suck-swallow pattern, medication only treats the symptom (acid burning) and not the root cause (air intake). This is precisely where a Speech and Language Therapist specialising in infant feeding comes in.
My role is to meticulously observe and assess your baby’s oral motor skills, latch, tongue function, and the efficiency of their SSB sequence. I look for subtle signs of inefficiency that contribute to excessive air swallowing.
- Is the tongue elevating correctly to create suction?
- Is the jaw stable, or is it excessively moving?
- Is the latch deep enough to prevent air leaks?
- Can the baby coordinate suck, swallow, and breathe without gasping?
By identifying these mechanical challenges, I can then implement targeted strategies to improve feeding efficiency and reduce air intake, often leading to a significant reduction in reflux-like symptoms and overall discomfort.
Strategies to optimise air management during breastfeeding
The good news is that many babies can learn to feed more efficiently with the right support. Here are some general strategies we might explore:
- Optimise latch and position: A deep, asymmetric latch is crucial. Experiment with different positions that allow for a deeper latch and better head/neck alignment, such as laid-back feeding or upright positions.
- Paced feeding (even at the breast): If your milk flow is very fast, consider removing your baby from the breast briefly if you hear excessive gulping or see him or her struggling to breathe. This allows him or her to catch up and manage the flow.
- Support the jaw and cheeks: Sometimes, gentle support to the baby’s jaw or cheeks can help them maintain a more stable, efficient suck. I can demonstrate specific techniques for this.
- Burping effectively: While burping won’t get rid of all swallowed air, upright burping positions and gentle back rubs can help release some of it.
- Pre-feed oral preparation: Gentle oral massage or stretches before a feed can sometimes ‘wake up’ the oral muscles and improve coordination.
Addressing the ‘Great Air Debate’ isn’t about blaming anyone; it’s about empowering parents with a deeper understanding of their baby’s feeding mechanics. By focusing on the how, not just the what, we can often resolve persistent feeding challenges, reduce discomfort, and make breastfeeding a more joyful, peaceful experience for both you and your little one.
If you suspect your baby’s gassiness or reflux symptoms are related to how they are managing air during feeds, don’t hesitate to reach out for a specialist assessment.
