Snoring in children can be caused by several factors, and while it is generally not a cause for concern, it may sometimes indicate underlying health issues. If your 2-year-old snores while sleeping, it could be due to various reasons such as sleep position, congestion, seasonal allergies, or upper respiratory tract infections. More serious causes of snoring in children include enlarged tonsils or adenoids, sleep apnea, or other sleep-related breathing disorders. It is important to monitor your child's sleeping patterns and look for signs of disturbed breathing or other associated symptoms to determine if further medical attention is required.
| Characteristics | Values |
|---|---|
| Occurrence | Snoring is common in children. Approximately 10 to 20% of kids snore, and up to 27% of children experience minor, occasional snoring. |
| Loudness | Loud snoring is less common in children and can be a cause for concern, especially if it interferes with sleep. |
| Causes | Snoring in children can be caused by various factors, including congestion due to a common cold, allergies, enlarged tonsils or adenoids, deviated septum, or narrowing of the nose from birth. It can also be influenced by sleeping position, with children more likely to snore when lying on their backs. |
| Health Concerns | Loud snoring associated with abnormal breathing, frequent awakenings, bedwetting, and other symptoms may indicate sleep-disordered breathing or obstructive sleep apnea (OSA). OSA affects 2-4% of children and can cause fragmented sleep, impacting physical health, mental health, learning, and behavior. |
| Treatment | Treatment options for snoring and associated conditions may include medication, surgery (such as tonsillectomy or adenoidectomy), lifestyle changes, or the use of a continuous positive airway pressure (CPAP) device. Improving sleep hygiene, such as maintaining a consistent sleep schedule and reducing light and screen exposure before bed, can also help. |

What You'll Learn
Enlarged tonsils or adenoids
The enlargement of tonsils or adenoids can be caused by various factors, including viral or bacterial infections, allergies, irritants, and gastroesophageal reflux. Enlarged tonsils can interfere with breathing and swallowing, while enlarged adenoids may block the nose or the eustachian tubes connecting the back of the throat to the ears.
If your 2-year-old is exhibiting signs of OSA or persistent snoring, it is recommended to consult a paediatrician or an otolaryngologist (ENT doctor). Doctors may recommend surgical removal of the tonsils (tonsillectomy) or adenoids (adenoidectomy) if the child experiences frequent infections, breathing difficulties, or other related health issues. These procedures are common in children and can help alleviate breathing problems and improve sleep quality.

Sleep-disordered breathing
Approximately 10% of children snore regularly, and about 2-4% experience OSA. Recent studies indicate that mild SDB or snoring may cause similar problems to OSA in children. The most obvious symptom of SDB is loud snoring that occurs on most nights. This can be interrupted by a complete blockage of breathing, with gasping and snorting associated with waking up from sleep.
Other symptoms of SDB include:
- Irritability and sleepiness during the day
- Difficulty concentrating in school
- Busy or hyperactive behaviour
- Bedwetting
- Learning difficulties
- Slow growth
If you are concerned about your child's snoring, you should seek advice from a pediatrician, who may refer your child to an otolaryngologist (ENT doctor) for diagnosis and treatment.

Obstructive sleep apnea
While snoring is common in children and often harmless, persistent and loud snoring may signal an underlying health issue such as sleep apnea. Sleep-disordered breathing can affect sleep quality and may have serious health consequences depending on its severity. Obstructive sleep apnea (OSA) is a condition in which there is a complete or partial upper airway obstruction during sleep, leading to decreased oxygen saturation or arousals from sleep. This can cause dramatic effects on childhood behaviour, neurodevelopment, metabolism, and overall health.
OSA is the most common type of sleep apnea, affecting 2-4% of children. It is characterised by constant lapses in a child's breath during the night, called apneas, which occur when the airway becomes blocked. These lapses can happen dozens of times per night and can cause fragmented sleep. An AHI (apnea/hypopnea index) score of 1 or greater is abnormal in children up to 13 years old.
The signs and symptoms of OSA in children include snoring, pauses in breathing, restless sleep, mouth breathing, night sweats, sleepwalking or sleep talking, and bedwetting. These symptoms can affect a child's daytime behaviour, focus, attention, emotional capacity, and academic performance. If left untreated, OSA can lead to growth and development challenges, loss of bladder control, and cardiopulmonary disease.
If you suspect your child may have OSA, it is recommended to consult a healthcare professional such as a paediatric otolaryngologist, who can help determine the best treatment plan. Treatment options may include surgery to remove tonsils or adenoids, or managing risk factors such as regular exercise, avoiding tobacco smoke, and addressing seasonal allergies.

Congestion or allergies
Congestion, allergies, and asthma can all cause snoring in toddlers. Congestion from a cold, allergies, or milk reflux can cause snoring in newborns, and this usually resolves as their airways mature. Children with seasonal allergies may have stuffy noses, which can cause snoring. Upper respiratory tract infections (colds) or allergies can cause congestion, leading to snoring. This is known as "primary snoring".
To address mild snoring caused by congestion or allergies, there are several home remedies you can try. Regularly cleaning the room and washing the bedding can help to remove dust and allergens from your toddler's environment. An air purifier can also be used to reduce dust and allergens in the air, which may otherwise irritate their airways. Steam inhalation and saline nasal sprays can help to clear nasal congestion. Nasal steroid sprays and nasal rinses can also be used to reduce inflammation and swelling in the nose.
If your child is experiencing allergies, medications such as antihistamines and decongestants might help. If your child's snoring is accompanied by other symptoms, such as mouth breathing, restlessness, gasping, difficulty waking in the morning, and daytime fatigue, it may indicate a more serious issue. Sleep apnea, enlarged tonsils, and other sleep-related disorders can cause snoring in children. If you suspect your child has sleep apnea, consult a pediatrician or a pediatric otolaryngologist, who can help determine the best treatment plan.

Poor sleep hygiene
Light snoring is common in children and may not require medical attention. However, persistent or loud snoring may signal an underlying health issue, such as sleep apnea, enlarged tonsils, or other sleep-related disorders. If your child is exhibiting signs of sleep-disordered breathing, such as repeated episodes of under-breathing, pauses in breathing, or restless sleep, it is important to seek medical advice.
Consistent Sleep Schedule
Establish a regular bedtime routine and stick to a consistent sleep schedule. This helps your child's body and mind associate the routine with settling down and preparing for sleep. Give your child a heads-up 30 minutes and then 10 minutes before bedtime. The bedtime routine should last around 20 minutes and include three to four quiet, soothing activities such as putting on pyjamas, brushing teeth, and reading a book.
Reduce Light Exposure and Screen Time
Limit bright lights and electronics at night. Use dim, warm-coloured lights in the evening, and dimmable lights with soft or warm bulbs if possible. Avoid blue light from electronic devices, and use the "night setting" if available. Turn off all screens at least one hour before bedtime and consider removing all devices from your child's bedroom.
Quiet and Comfortable Bedroom
Set up your child's bedroom to be as quiet and comfortable as possible. If there is unavoidable noise or light, provide your child with earplugs and a sleep mask. Keep the room cool, unless your child sleeps better in a warm room, and use a fan or air conditioning if needed.
Daytime Habits
Encourage your child to get some exercise during the day, but avoid evening exercise as it may disrupt sleep. Any activity that gets your child's heart rate up for at least 30–60 minutes during the day can promote better sleep. Limit daytime naps unless your child is recovering from illness or needs to catch up on sleep.

Frequently asked questions
There are many reasons why your 2-year-old may snore while sleeping. Light snoring is common in children and may be caused by their sleeping position (children are more likely to snore when lying on their backs), congestion, or seasonal allergies.
Loud snoring becomes a medical concern when it is associated with abnormal breathing and interrupts sleep. If your child is not getting enough sleep because of sleep-disordered breathing, this may lead to fragmented sleep and corresponding problems related to behaviour, thinking, health, and learning.
If you are concerned about your child's snoring, you should talk to their doctor or pediatrician. They may recommend treatments with medications or procedures, such as a prescription nasal spray, an anti-inflammatory allergy medication, or surgery.
