What Is Sleep Apnoea?
Sleep apnoea is a condition where breathing repeatedly stops and starts during sleep. In children, the most common type is obstructive sleep apnoea (OSA), which means something is physically blocking the airway. When a child with OSA is asleep, the muscles in their throat relax, and if the airway is already narrow or floppy, it can temporarily close.
This interrupts their breathing and, in turn, their sleep. These pauses might only last a few seconds, but they can happen dozens—even hundreds—of times a night. And while your child might not fully wake up each time, their body does—causing restless sleep and daytime tiredness.
Why Are Children with Down Syndrome More Likely to Have Sleep Apnoea?
Children with Down syndrome are more prone to obstructive sleep apnoea because of several physical and muscular differences that can affect the airway:
These factors don’t guarantee sleep apnoea, but they do increase the risk. That’s why routine screening and early awareness are especially important for families in the Down syndrome community.
Signs and Symptoms: What Should I Look Out For?
You may not be watching your child sleep every night—but even small signs during the day can indicate disrupted sleep.
Here are the most common symptoms of sleep apnoea in babies and toddlers:
During sleep:
During the day:
Keep in mind: not all snoring is sleep apnoea, and not all children with sleep apnoea snore. If something about your child’s sleep feels “off,” it’s worth checking in with your healthcare provider.
How Is Sleep Apnoea Diagnosed?
If your child’s doctor suspects sleep apnoea, the gold standard for diagnosis is a sleep study—also called a polysomnogram. This test is usually done overnight at a sleep clinic or hospital.
During the study, your child will be connected to gentle monitors that track:
The idea of a sleep study might sound daunting, but most centres are very child-friendly. You can usually stay with your child throughout the night, and the process is safe and non-invasive. Some hospitals also offer home sleep tests, though they’re not always recommended for very young children or for an initial diagnosis.
What Are the Treatment Options?
If your child is diagnosed with sleep apnoea, you may feel a mix of emotions—relief to have an answer, concern about what’s next, or worry about the word “treatment.” But here’s the reassuring truth: There are several effective ways to treat sleep apnoea, and your child’s doctor will help you choose the best approach based on the cause and severity.
Here are some of the most common treatment options:
1. Adenoid and/or Tonsil Removal (Adenotonsillectomy) - This is often the first line of treatment, especially if enlarged tonsils or adenoids are causing the blockage. Surgery can dramatically improve breathing and sleep quality in many children.
2. Positive Airway Pressure (CPAP or BiPAP)- If surgery isn’t effective—or if your child isn’t a good candidate—CPAP or BiPAP therapy may be recommended. These machines deliver gentle air pressure through a mask to keep the airway open during sleep. It can take time for children (and parents) to get used to the machine, but many families find it becomes a normal and helpful part of bedtime.
3. Weight Management - For older children, maintaining a healthy weight can help reduce pressure on the airway. That said, many young children with Down syndrome aren’t overweight, so this may not be relevant in early years.
4. Orthodontic or ENT Interventions In some cases, palate expanders or nasal surgeries may be considered to improve airflow. This would usually be part of a longer-term care plan guided by specialists.
What If It Goes Untreated?
Left untreated, sleep apnoea can lead to:
But remember: these risks are significantly reduced with early detection and treatment. So, if you’re worried, don’t wait. Trust your instincts. Speak to your child’s doctor and ask for a referral to a sleep specialist if needed. Getting answers sooner can make a big difference in your child’s health and daily quality of life.
Encouraging Words for the Journey
If your child is facing sleep apnea, you might feel overwhelmed with medical terms, appointments, and decisions. But you don’t have to go through this alone—and it’s okay to take it one step at a time. Many parents in the Down syndrome community have walked this road and come out the other side with a well-rested, thriving child. The journey may involve tests and equipment or even surgery—but the outcome is often a huge improvement in sleep, mood, growth, and development. Most importantly, sleep apnoea is manageable—and noticing the signs early is one of the most loving, protective things you can do for your child.
In Closing
Yes, sleep apnoea can be more common in babies and toddlers with Down syndrome—but it doesn’t have to steal their joy, health, or growth. With the right information and support, you can help your child breathe easier, sleep better, and thrive. If you're ever unsure, reach out. Ask questions. Talk to your doctor. And remind yourself: noticing, caring, and taking action when something seems off makes you a great parent. You’re doing beautifully—and you’re not alone.

Why Are Children with Down Syndrome More Likely to Have Sleep Apnoea?
Children with Down syndrome are more prone to obstructive sleep apnoea because of several physical and muscular differences that can affect the airway:
- Smaller upper airways and a larger tongue (relative to mouth size)
- Low muscle tone (hypotonia) in the throat and neck muscles
- Enlarged tonsils and adenoids
- Narrow nasal passages
- A slightly flattened facial structure, which can contribute to airflow restriction
These factors don’t guarantee sleep apnoea, but they do increase the risk. That’s why routine screening and early awareness are especially important for families in the Down syndrome community.
Signs and Symptoms: What Should I Look Out For?
You may not be watching your child sleep every night—but even small signs during the day can indicate disrupted sleep.
Here are the most common symptoms of sleep apnoea in babies and toddlers:
During sleep:
- Loud snoring (especially if it’s consistent or happens most nights)
- Pauses in breathing or gasping for air Restless sleep (tossing and turning)
- Sleeping in unusual positions (like arching their neck back to open the airway)
- Mouth breathing
- Frequent waking or trouble staying asleep
During the day:
- Excessive sleepiness or difficulty staying alert
- Irritability or moodiness
- Poor attention or delayed development
- Struggles with feeding or growth (in babies)
Keep in mind: not all snoring is sleep apnoea, and not all children with sleep apnoea snore. If something about your child’s sleep feels “off,” it’s worth checking in with your healthcare provider.
