Overview

If your baby has been diagnosed with laryngomalacia, you may feel overwhelmed by their noisy breathing, sleep disturbances, or feeding challenges. Luckily, through numerous studies, medical research has been able to identify safe and effective positioning techniques that can reduce symptoms and improve your baby’s quality of life. A comprehensive 14-year study has concluded that the safest position for a baby with laryngomalacia during sleep is the side-sleeping position, as obstructive sleep apnea (OSA) is often more severe when babies are placed on their backs.² Side-sleeping decreases the number and severity of breathing obstructions, reduces carbon dioxide retention, and lowers the effort required to breathe during sleep. Specifically, the median obstructive apnea-hypopnea index (OAHI) in the supine position was 22 events per hour, compared to just 7 events per hour in the side position. Breathing was not only easier but also more efficient in the side position.² In regards to feeding, it has been found that babies should always be held in an upright position during and after meals, ideally for at least 20 to 30 minutes.¹ This helps reduce gastroesophageal reflux, which frequently arises with laryngomalacia and can worsen airway obstruction. By feeding your baby upright, you will minimize the chances of food entering the airway. Therefore, knowing how to position your baby safely can make a significant difference in their comfort and health. 

Laryngomalacia

Laryngomalacia is the most common congenital cause of noisy breathing in infants, often presenting within the first few weeks of life.² It is caused by floppy tissues above the vocal cords that collapse inward during inspiration, narrowing the airway.⁵ This results in stridor, feeding difficulty, and in severe cases also sleep-disordered breathing such as obstructive sleep apnea. While most cases resolve by 18-24 months of age, appropriate positioning is essential for symptom management while the condition cures itself.² 

General safety guidelines

As laryngomalacia varies in severity, treatment and positioning strategies should always be individualised. This often includes assessment by a pediatrician or pulmonologist and testing via flexible laryngoscopy and polysomnography.² A study on Nature evaluated 79 infants under 9 months old and emphasised the importance of customising treatment, ranging from observation to surgical intervention, based on each child’s symptoms, growth, and sleep study results.² 

Safe sleep position

Following intensive research, it was concluded that sleep-disordered breathing in infants with laryngomalacia is sleep-position dependent. In most infants, OSA was significantly worse when lying on their backs.² Supine sleep was associated with increased apnea events, more labored breathing, and elevated end-tidal carbon dioxide levels. In contrast, when placed on their side, infants experienced fewer obstructive events, improved oxygen saturation, and reduced work of breathing.² 

Even when other contributing conditions, such as reflux or craniofacial abnormalities, were ruled out, the benefit of side-sleeping was still prominent. However, since current public health recommendations advise all infants to sleep on their backs to reduce the risk of sudden infant death syndrome, side-sleeping should only be done under medical guidance.² In the study, 42% of infants were prescribed side-sleeping as part of their treatment plan, and 75% of these were also sent home with pulse oximetry to monitor oxygen levels while sleeping.² For those with more severe respiratory compromise, additional treatment included high-flow nasal cannula therapy or continuous positive airway pressure (CPAP), often in combination with positional therapy.²

Safe feeding positioning

Feeding is another critical process where positioning makes a difference. Babies with laryngomalacia often experience worsened breathing during feeds due to increased airflow demand and reflux.³ To reduce these complications, feeding should always be done in an upright position. This position helps to prevent reflux and support better control over airway patency.⁴ 

Post-feed care is just as important, where babies should remain upright for 20-30 minutes after feeding.¹ This practice reduces the likelihood of reflux and further protects the airway. It has also been found that frequent, gentle burping during feeds can help reduce intra-abdominal pressure and reflux risk.⁴ You should never feed a baby lying flat, especially one with laryngomalacia. In addition, studies also noted a significant percentage of infants with this condition had growth failure, underlining the importance of optimising feeding practices to ensure sufficient intake and avoid aspiration or feeding fatigue.² The presence of growth failure in many infants highlights the importance of monitoring overall development and weight gain. 

When to seek medical help

Not all infants with laryngomalacia require strong treatment, but certain signs indicate a need for further intervention. These include worsening stridor, poor weight gain, feeding refusal, frequent choking or gagging during feeds, and signs of sleep apnea such as pauses in breathing or turning blue.³ In such cases, more advanced diagnostics and possibly surgery, like supraglottoplasty, may be warranted.⁵ In most studies, around 5% of infants required surgical intervention, suggesting that many cases can be managed successfully with positioning and supportive care.² 

Summary

Positioning plays a major role in reducing airway obstruction, minimising reflux, and improving overall breathing patterns in infants with laryngomalacia. The best sleeping position for a baby with laryngomalacia and documented OSA is on their side, not on their back, when advised by a healthcare provider. The position decreases the frequency and severity of obstructive breathing events during sleep.

 When feeding, babies should always be kept upright and remain so for at least 20 to 30 minutes afterward to reduce reflux and protect their airway. These simple but medically supported positioning strategies can provide significant relief and safety to infants living with laryngomalacia. The need for monitoring this or any additional treatments should be evaluated by your baby’s doctor. 

FAQs

What should I do if I’ve tried positioning changes and my baby is still having problems?

If you have adjusted your baby’s sleep and feeding positions and symptoms like stridor, feeding difficulty, or growth concerns are still present, you should follow up with your pediatrician or specialist. Persistent symptoms may mean that your baby needs a more detailed evaluation, which could include another sleep study, flexible laryngoscopy, or consultation with a pediatric ENT or pulmonologist.²

 In some cases, additional interventions such as medication for reflux, use of high-flow nasal cannula, or surgical treatment may be considered. If you notice that your baby seems to be working harder to breathe, feeds are taking longer and causing distress, or you notice pauses in breathing, medical guidance is essential. 

Is side-sleeping really safe if I’ve always been told to put my baby on their back?

Yes, in babies with diagnosed laryngomalacia and confirmed sleep apnea, the benefits of side-sleeping can outweigh the general guidance. This decision however should not be made on your own, it needs to come from a healthcare professional. The latter will most likely suggest a home oxygen monitoring system, which adds a layer of safety. Therefore, yes side-sleeping can be safe, but only if it is part of a medical plan tailored to your child. 

My baby makes loud breathing sounds in their sleep. Does that mean they’re in danger?

Not necessarily! The squeaky or wheezy sound, called stridor, is the most common symptom of laryngomalacia. It is often worse during sleep, feeding, or crying, but the loudness does not necessarily translate to danger. What matters more is how the baby is breathing, for instance, whether they are pulling in at the chest, turning pale or blue, or having pauses in their breathing. Those are the signs that something more serious might be going on. If you are unsure, it is always best to get checked, but you do not need to panic at every sound, as most babies with laryngomalacia grow out of it without complications. 

How long should I keep my baby upright after feeding?

It is recommended that you keep your baby in an upright position for at least 20 to 30 minutes after each feed. This helps minimise gastroesophageal reflux, which is very common in infants with laryngomalacia. When a baby is laid flat too soon after feeding, stomach contents can more easily flow back up into the esophagus and even the throat, irritating the already sensitive airway and worsening noisy breathing or stridor. Holding your baby upright gives gravity time to help the food settle in the stomach, reducing the chances of regurgitation, aspiration, or breathing disruption.
