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

ByLondon Speech and Feeding

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:

  1. 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.
  2. 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.
  3. 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.
  4. 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.
  5. 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.

Tongue-Tie: A complex issue requiring careful assessment

Tongue-Tie: A complex issue requiring careful assessment

ByLondon Speech and Feeding

Tongue-tie, or ankyloglossia, is a condition where the lingual frenulum, the thin piece of tissue that connects the underside of the tongue to the floor of the mouth, is too short or tight. Tongue-tie is quite common in babies and is often not detected after birth. Tongue-tie can lead to a difficult start with breast feeding as it makes it very difficult for the baby to latch effectively.

In my clinical experience as a feeding therapist, I have seen many babies who were not able to latch well due to the frenulum being tight. In many cases an experienced feeding speech therapist/lactation consultant can really make a difference and help a new mum to latch the baby even though the tongue is tethered to the floor of the baby’s mouth. In some cases the frenulum can be divided and once this has been done, in some cases, feeding improves immediately or soon after the division. But this is not always the case. I have seen several babies who have had as many as four tongue-tie divisions and feeding was still difficult.

It is important to say that while tongue-tie can sometimes impact speech and feeding, it’s important to note that it’s not always the root cause of these difficulties. In recent years, there has been a surge of interest in tongue-tie division surgeries, with some cases being unnecessary. It’s crucial to understand the complexities of tongue-tie and the role of speech therapy in addressing related challenges.

The impact of tongue-tie on speech and feeding

When tongue-tie is severe, it can interfere with the tongue’s ability to move freely, affecting speech production and swallowing. Some common speech and feeding difficulties associated with tongue-tie include:

  • Feeding difficulties: Challenges with sucking, chewing, and swallowing.
  • Drooling: Excessive drooling due to difficulty controlling saliva.
  • Speech problems: Difficulty producing certain sounds, such as /l/, /r/, /t/, /s/ and /d/.

The importance of comprehensive assessment

Before considering any surgical intervention for tongue-tie, it’s essential to undergo a thorough evaluation by a qualified speech-language therapist (SLT). An SLT can assess the severity of the tongue-tie, its impact on speech and feeding, and determine if surgery is necessary.

  • Functional assessment: The SLT will assess the tongue’s range of motion, its impact on speech sounds, and the child’s overall oral motor skills.
  • Feeding evaluation: The SLT will observe the child’s feeding patterns and identify any difficulties related to tongue-tie.
  • Differential diagnosis: The SLT will rule out other potential causes of speech and feeding difficulties, such as apraxia of speech, dysarthria, or sensory processing disorders.

The role of speech therapy

Even in cases where tongue-tie is present, speech therapy can often be highly effective in addressing speech and feeding difficulties. Here’s how speech therapy can help:

  • Articulation therapy: Targeting specific speech sounds that may be affected by tongue-tie.
  • Childhood Apraxia of Speech (CAS): if the diagnosis by the SLT has shown that in fact the child has motor planning difficulties then there are very specific and effective treatment programmes that help with this and can make a real difference over time.
  • Feeding therapy: Strategies to improve swallowing, chewing, and oral-motor skills.
  • Sensory integration: Addressing underlying sensory processing issues that may contribute to feeding difficulties.

London Speech and Feeding Case Study: The importance of comprehensive assessment

One of my clients was initially diagnosed with tongue-tie and recommended for surgery at the age of eight years old. His speech had been perceived by parents and teachers as ‘mumbled and unclear’.

However, after a thorough evaluation, I was able to determine that the child’s primary issue was apraxia of speech, a neurological disorder that affects motor planning for speech. Parents decided to wait with surgery and trust my judgment and we proceeded with weekly intensive speech therapy to address motor planning difficulties around tricky sounds and words. I am delighted to say that the child’s speech has improved significantly, demonstrating the importance of comprehensive assessment and individualised treatment. He is no longer seen as a candidate for an operation, which would have been traumatic for him at his age and, as it turned out, entirely unnecessary.

Below is a short video clip of my working on the /l/ sound with this child.

Conclusion

Tongue-tie is a complex issue that requires careful evaluation and individualised treatment. While surgery may certainly be necessary in some cases, it’s essential to consider the potential benefits and risks. Speech therapy can be a highly effective approach for addressing speech and feeding difficulties associated with tongue-tie, even in cases where surgery is still required. By working with a qualified speech-language therapist, parents can ensure that their child receives the best possible care and support.

Answers to very common questions I get as a Feeding Therapist

ByLondon Speech and Feeding

What are hunger cues in newborn babies? How do we recognise when our baby is hungry? How often should we feed our baby?

These are very common questions I get as a Feeding Therapist. And so I thought I would write a blog on it.

First-time parents’ journey

First-time parents often imagine that feeding, particularly breastfeeding, will be an easy and natural process without too many problems. It can be a rude awakening to find that feeding our newborn is not at all easy and can be fraught with complications. It is fair to say that in most cases by the time our baby is about eight weeks old most mums have got the hang of feeding, either by breast and/or bottle, and things are falling into place.

But until that time it can be a difficult journey:

  • getting to know one’s baby,
  • getting to know their feeding rhythm,
  • falling in with it,
  • TRUSTING that baby knows what they need and knows when they have had enough,
  • TRUSTING and not going crazy with going down an on-line rabbit hole of information and guidance mostly unnecessary and often quite simply FALSE!

Many mums I have met set out with the best intentions to breastfeed for as long as possible. However, they arrive in my clinic anxious and often have given up with the breast; now we are on bottle feeds and things are still very tricky for several reasons. There are too many reasons for this blog to cover but I thought I would start with the basics and ‘reading hunger cues’ is one of those early basics.

Reading hunger cues

So let’s dive in:

Newborns communicate hunger through a variety of cues. Here are some early signs to look for:

  • Early hunger cues: These are the best times to respond to baby’s hunger for a more peaceful feeding. Look for things like:
    • Becoming more alert and active
    • Turning head from side to side in the cot
    • Rooting (turning their head towards your breast or a bottle, especially when stroked on the cheek)
    • Putting hands/fists to mouth
    • Sucking on fists or lips
    • Opening and closing mouth, smacking sounds
TOP TIP: THIS IS WHERE YOU SHOULD GET READY TO FEED. Breast or bottle. Either way get ready. We do not want our baby to get into later hunger cues, which are below:
  • Later hunger cues: If we miss the early cues, babies will progress to more insistent hunger cues. These include:
    • Fussiness or whimpering
    • Rapid sucking motions
    • Increased squirming
    • Head bobbing

Generally, remember that we do not want our baby to cry for their food. Because once they are riled and cry they are not relaxed enough to latch, especially when latching is hard!

Feeding on demand vs. scheduled feeds

We now know and have researched how babies are fed best and safest, how weight gain is ensured best, both for breastfed and bottle-fed babies.

It’s generally recommended to feed on demand—unless your baby is tube-fed or has some other pressing health concerns or is failing to thrive.

What are the benefits of on demand feeding?

  • We need to respond to baby’s individual needs and hunger cues because every person is unique!
  • Babies need to learn and regulate their own hunger and satiation cycles
  • Promotes better weight gain and growth
  • Leads to more peaceful feeding experiences

Scheduling can come later

A loose schedule might emerge naturally when your baby is around 2–3 months old, but it’s best to follow your baby’s lead.

Tips:

  • Some newborns may feed every 2–3 hours, while others go longer stretches. Pay attention to your baby’s cues and feeding habits.
  • Crying is a late hunger cue, and frequent crying can make feeding more difficult. Responding to earlier cues is best.
  • If you have concerns about your baby’s feeding patterns or weight gain, consult with a Speech and Language Therapist/Dysphagia Therapist and/or Lactation Consultant.

Do get in touch if you would like some in-person or on-line 1:1 support with this. It can be overwhelming to figure it all out alone.
