    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.

    Baby-Led Weaning: A Speech and Language Therapist’s Take

    ByLondon Speech and Feeding

    Let’s face it, introducing solids is a rollercoaster for parents. You’re bombarded with advice (solicited and otherwise) on purees, spoon-feeding, and the much-discussed ‘baby-led weaning’ (BLW). As a speech-language/feeding therapist I see the world through the lens of communication and development, as well as safe munching and swallowing. BLW can be a fantastic option for many little foodies. But is it right for yours? Let’s take a dive into the messy, hilarious world of toddler feeding.

    BLW in a nutshell

    Your baby, perched in their highchair, eyes wide with excitement and curiosity reaches out for a platter of food. He/She grabs a fat avocado slice, and curiously explore it with his/her lips, gums and tongue. He/She spits some of it out, mashes bits of it into his/her hair, there was a tiny swallow and the rest is smeared onto the high chair tray. Now he/she grabs a bit of the banana and rinse and repeat as before, except this one he/she keeps in his/her mouth for bit longer and takes a tiny bit more before the rest gets deposited into his/her bib.

    This, in a nutshell, is BLW! It’s all about letting your little one take the lead in exploring new foods, textures, and tastes. No spoon-feeding, just pure, messy, self-directed feeding fun.

    The pros of letting your little one loose on solids:

    • Motor Skills: BLW is a sensory party for developing motor skills. Picking up that slippery banana or gumming a chewy piece of toast strengthens those tiny hands and mouth muscles. These are the very skills they’ll need for future talking and chewing.
    • Texture Time: BLW exposes your baby to a variety of textures right from the start. Think soft, steamed broccoli florets or smooth, banana half-slices. This sensory exploration helps them develop an understanding of different textures in the world, which can translate to better oral motor skills needed for speech development.
    • Independence: BLW fosters a sense of self-feeding independence. Your toddler learns to control how much he/she eats and the pace of his/her meal. This can lead to better self-regulation later on, not just with food, but in other areas of his/her development too.
    • A wider variety of flavours: BLW encourages exposure to a wider variety of tastes and smells. Let your baby discover the sweetness of roasted sweet potato or the tang of mashed avocado! This early exploration can lead to less picky eating down the road.

    There are some valid concerns:

    • Gagging vs. Choking: One of the biggest concerns parents have about BLW is choking. However, gagging is a natural reflex that helps babies learn to move food safely around their mouths. Choking is much rarer, and with proper food selection and supervision, the risk is very low. The con here really is parental anxiety more than anything else and if you can overcome this then a bit of gagging is just fine and part of the process. Choking, again most children do choke occasionally a bit! Of course, close supervision and common sense is very important here.
    • It’s ever so messy!: Be prepared for mashed banana on the highchair tray, rogue peas flung across the room, and a general sense of chaos. But then again, this is an important part of the learning process! I would encourage you to embrace the mess (within reason and your personal tolerance level) and focus on the fun of exploration.
    • Nutritional Concerns: Some parents worry that babies won’t get enough nutrients with BLW. While it might take a while for them to master the art of self-feeding, a healthy child’s body is pretty good at self-regulating. Offer a variety of healthy options, and he/she will eventually get the hang of it.

    BLW: Is it right for your Little One?

    BLW isn’t a one-size-fits-all approach. Here are some things to consider:

    • Developmental Milestones: Babies should be able to sit up with good head control and show an interest in food before starting BLW.
    • General good health and absence of food intolerances, allergies, or other significant health issues which might dictatea more controlled feeding regime.
    • Gag Reflex: A strong gag reflex is a good sign. It shows your baby’s natural ability to move food safely around their mouth. If, however, your baby’s gag is overly sensitive and causes frequent bouts of vomiting please consult your health care professional for an assessment (GP, Paediatrician, Dietician, Speech and Language – Feeding Therapist).
    • Your Comfort Level: BLW requires a relaxed and patient approach. If you’re feeling stressed about the mess or potential choking hazards, it might not be the right fit for you.

    A final mouthful:

    BLW can be a fantastic way to introduce your baby to solids. It promotes exploration, independence, and a love for food. Remember, there’s no pressure to go all-in on BLW. You can always combine it with spoon-feeding or purees to find an approach that works for your family and your child. The most important thing is to create a positive and relaxed mealtime environment where your little one can explore the wonderful world of food at their own pace.

    P.S. As an SLT, I always recommend chatting with your health care professional. This way you can address any concerns you might have and ensure your baby is developmentally and physically on track for this exciting new chapter.
