A stuffy nose can make feeding and settling more difficult for a baby. You may notice noisy breathing, frequent waking, difficulty nursing or taking a bottle, or frustration when your baby tries to breathe through their nose.
It may seem helpful to raise the baby’s head or choose a different sleeping position. However, the safest position for a congested baby remains the same:
Place your baby flat on their back for every nap and nighttime sleep.
Use a firm, flat, level mattress in a safety-approved crib, bassinet, portable crib, or play yard. Do not place a pillow, wedge, rolled towel, positioner, or other object beneath or around the baby. Raising one end of the sleep surface can cause a baby to slide into a position that interferes with breathing.
Safety notice: This article provides general educational information and does not replace advice from your baby’s pediatrician or another qualified healthcare professional. Young babies can become unwell quickly, so seek professional advice when breathing, feeding, alertness, or hydration concerns arise.
What Is the Best Sleep Position for a Congested Baby?
A congested baby should be placed completely on their back at the beginning of every sleep.
This applies to:
- newborns;
- premature babies;
- babies with a cold;
- babies with nasal congestion;
- babies with reflux;
- daytime naps;
- nighttime sleep.
Back sleeping carries the lowest risk of sudden infant death syndrome. The sleep surface should remain firm, flat, level, and free from loose or soft objects.
Congestion is not a reason to place a baby:
- on their stomach;
- on their side;
- on a pillow;
- in an inclined sleeper;
- in a nursing pillow or lounger;
- in a car seat or swing for routine sleep.
A baby may sound noisier while lying flat because mucus is present, but changing to an unsafe sleep position is not the solution.
Should You Elevate a Congested Baby’s Head?
No. Do not elevate the baby’s head by raising the mattress or placing something underneath it.
Inclined surfaces can cause a baby to slide downward. Their chin may move toward their chest, potentially narrowing or blocking the airway. A baby may also roll or become trapped against the side of an inclined product.
Avoid:
- placing books beneath crib legs;
- raising one end of the mattress;
- inserting a wedge under or above the mattress;
- putting a pillow beneath the baby’s head;
- using rolled blankets or towels;
- buying an “anti-congestion” or “anti-reflux” positioner;
- allowing routine sleep in an inclined chair.
Even when a product is marketed as breathable or designed for congestion, it should not replace a firm, flat infant sleep surface.
Can a Congested Baby Sleep on Their Side or Stomach?
Do not intentionally place a congested baby on their side or stomach.
Side sleeping is unstable, making it easier for a baby to roll onto their stomach. The NIH recommends placing babies on their backs for every sleep.
When an older baby can independently roll from back to stomach and stomach to back, continue placing them on their back initially. They can generally remain in the position they choose after rolling, provided that:
- they reached the position independently;
- they are no longer swaddled;
- the mattress is firm, flat, and level;
- the crib contains no pillows, blankets, toys, positioners, or bumpers.
Do not use an object or restraint to prevent a rolling baby from changing position.
Can a Congested Baby Sleep in a Car Seat or Swing?
Car seats are designed for travel, not routine sleep outside the vehicle.
A baby’s head may slump forward while seated, potentially interfering with breathing. Swings, bouncers, reclined chairs, and other sitting products also do not provide the firm, flat, level surface recommended for infant sleep.
When a baby falls asleep in one of these products, move them to a suitable crib, bassinet, portable crib, or play yard as soon as practical.
Do not loosen or add padding to a car seat in an attempt to make it more comfortable for sleep.
Safe Ways to Help a Congested Baby Before Sleep
You cannot safely solve congestion by changing the baby’s sleep position. Instead, help clear the nose before feeding and bedtime.
Use plain saline
Plain saline drops or mist can help loosen thick or dried mucus.
Use a product intended for babies and follow its directions or your pediatrician’s instructions. Avoid medicated nasal products unless a healthcare professional specifically recommends one.
The American Academy of Pediatrics recommends plain saline followed by gentle suction as a way to ease a baby’s stuffy nose.
Use gentle nasal suction
After saline has loosened the mucus, a bulb syringe or nasal aspirator may help remove it.
When using a bulb syringe:
- Squeeze the bulb before bringing it to the nostril.
- Place the tip gently at the opening rather than pushing it deeply.
- Release the bulb slowly.
- Clean the device according to its instructions.
Suction may be particularly useful before feeding or sleep when congestion interferes with breathing through the nose. Excessive or forceful suction can irritate the nasal passages, so use it gently rather than repeatedly when it is not needed.
Try a cool-mist humidifier
A cool-mist humidifier may help when indoor air is dry. Added moisture can loosen nasal secretions and make them easier to clear.
Place the humidifier where the baby cannot reach it and where mist does not directly soak the crib or bedding.
Clean and dry it according to the manufacturer’s instructions. Poorly maintained humidifiers can develop mold, bacteria, or mineral buildup.
A cool-mist model is preferable around children because hot steam can cause burns if the unit spills or is touched.
Support normal feeding
Congestion can make it harder for a baby to feed because they need to pause to breathe.
Clearing the nose shortly before feeding may help. Offer normal breast milk or formula feeds as appropriate for the baby’s age and feeding plan. Smaller, more frequent feeds may sometimes be easier, but discuss significant feeding difficulty with the pediatrician.
Do not give water, tea, juice, honey, or another home remedy to a young baby unless a qualified healthcare professional recommends it.
Hold the baby upright while awake
You may hold your baby upright while both of you are awake. This can provide comfort and may make breathing or feeding feel easier.
Before you become sleepy, transfer the baby to their own firm, flat sleep space and place them on their back.
Do not fall asleep:
- with the baby on your chest;
- while sitting on a couch or armchair;
- while holding the baby in an adult bed;
- with the baby supported by pillows.
Should You Use Cold Medicine for a Congested Baby?
Do not give an infant an over-the-counter cough or cold medicine unless a qualified healthcare professional specifically directs you to use it.
The FDA does not recommend over-the-counter cough and cold medicines for children younger than two because they can cause serious and potentially life-threatening side effects. Manufacturers commonly label these products not to be used in children younger than four.
This includes some products containing:
- decongestants;
- antihistamines;
- cough suppressants;
- multiple cold and flu ingredients.
Do not use an adult product in a smaller amount. Do not combine products or rely on a dose found in an old article, social-media post, or parenting forum.
Contact the pediatrician or pharmacist before giving medicine to a baby.
What Causes Congestion in Babies?
A stuffy or runny nose can occur with several conditions, including:
- a common cold;
- respiratory syncytial virus;
- influenza;
- another respiratory infection;
- dry air;
- smoke or another irritant;
- allergies in some older babies;
- normal mucus and narrow newborn nasal passages.
Symptoms alone may not identify the cause. Respiratory infections can begin with mild congestion and become more serious over several days. RSV, for example, may begin with a runny nose, reduced feeding, and cough before progressing to wheezing or difficulty breathing.
Contact the pediatrician when symptoms are worsening or when you are concerned about a young infant.
When Should You Call the Pediatrician?
Contact your baby’s healthcare provider when:
- congestion interferes with feeding;
- the baby takes much less milk than usual;
- wet diapers become less frequent;
- coughing is frequent or worsening;
- the baby is unusually sleepy, irritable, or difficult to settle;
- symptoms improve and then become worse;
- congestion lasts longer than expected;
- the baby has an underlying heart, lung, immune, or premature-birth history;
- you are uncertain whether the baby is breathing comfortably.
A baby younger than 12 weeks with a temperature of 100.4°F or higher needs prompt medical evaluation.
Signs That Need Urgent Medical Attention
Seek urgent medical care when the baby:
- is breathing rapidly or struggling to breathe;
- has skin pulling inward between or beneath the ribs;
- has blue, gray, or unusually pale lips or facial coloring;
- makes repeated grunting or unusual breathing sounds;
- has pauses in breathing;
- cannot feed because of breathing difficulty;
- is difficult to wake or does not interact normally;
- shows signs of significant dehydration;
- has a seizure;
- appears seriously unwell.
Fast or difficult breathing, ribs pulling inward, blue coloring, reduced alertness, and dehydration are warning signs described by the CDC for serious respiratory illness in children.
Call emergency services when the baby stops breathing, turns blue or gray, is unresponsive, or is experiencing severe breathing difficulty.
Frequently Asked Questions
Should a congested baby sleep flat?
Yes. Place the baby flat on their back on a firm, level sleep surface. Do not incline the mattress or add a pillow or wedge.
Can I place a pillow under the crib mattress?
No. Raising one end of the mattress creates an incline and may cause the baby to slide into a position that restricts breathing.
Can my baby sleep in a swing when congested?
A swing is not an appropriate routine sleep surface. Move a sleeping baby to a firm, flat, level crib, bassinet, portable crib, or play yard.
Can I suction my baby’s nose before sleep?
Plain saline and gentle suction can help clear mucus, particularly before feeding or sleep. Follow the device instructions and avoid forceful or unnecessary repeated suction.
Is a humidifier helpful for congestion?
A cool-mist humidifier may help when the air is dry. It must be cleaned regularly to prevent mold, bacteria, and mineral buildup.
Should I wake a congested baby?
Congestion alone does not always require waking a comfortably sleeping baby. Check that the baby is on their back in a safe sleep space and appears to be breathing normally. Seek professional advice when feeding, breathing, hydration, alertness, or fever concerns arise.
Can congestion make a baby breathe loudly?
Nasal mucus and narrow nasal passages can make a baby’s breathing sound noisy. Noise alone does not indicate severity. Watch the baby’s breathing effort, skin color, feeding, alertness, and hydration rather than relying only on the sound.
The Bottom Line
The best sleep position for a congested baby is flat on their back.
Congestion does not make stomach sleeping, side sleeping, inclined mattresses, car seats, swings, pillows, or positioners safe.
To help your baby:
- use plain saline when appropriate;
- clear loosened mucus gently;
- consider a properly maintained cool-mist humidifier;
- support normal feeding;
- hold the baby upright only while you are awake;
- contact the pediatrician when symptoms interfere with feeding or worsen;
- seek urgent care for breathing difficulty, blue coloring, reduced alertness, or dehydration.
