Baby Always Congested (Stuffy Nose)
The short answer
Babies are naturally noisy breathers because their nasal passages are very small. Many parents worry their baby is "always congested" when the sounds they hear are actually normal newborn breathing. True chronic congestion can be caused by frequent colds, dry air, or irritants. Saline drops and gentle suctioning are the safest and most effective treatments for infant congestion.
This is one of the most common questions parents ask. Searching for answers means you care.
By Age
What to expect by age
0-3 months
Newborns are obligate nose breathers, meaning they breathe primarily through their noses. Their nasal passages are very narrow, so even a small amount of mucus can cause audible congestion. Snorting, snuffling, and squeaking sounds are very common and usually normal. Saline drops (1-2 drops per nostril) followed by gentle bulb syringe suctioning is the recommended treatment. Never use over-the-counter decongestants or cold medicines in infants.
3-6 months
Some congestion is often from exposure to colds, especially if your baby has older siblings or is in daycare. Environmental factors like dry air, dust, pet dander, or strong scents can also contribute. A cool-mist humidifier in the room and keeping the air clean can help. Nasal saline spray or drops remain the best remedy. Elevating the head of the crib mattress slightly is no longer recommended due to safety concerns.
6-12 months
Babies in this age range may seem perpetually congested during cold and flu season, as one cold can take 7-10 days to resolve before the next one begins. If your baby is feeding well, sleeping reasonably, and growing normally despite the congestion, this is usually just the normal pattern of building immunity. Teething can also temporarily increase nasal discharge.
12 months+
If nasal congestion persists year-round and is not related to colds, allergies may be a consideration, though true allergic rhinitis is uncommon before age 2. Enlarged adenoids can also contribute to chronic congestion and mouth breathing in toddlers. If your toddler consistently breathes through their mouth, snores heavily, or seems to have obstructed breathing during sleep, discuss this with your pediatrician.
What Should You Do?
When to take action
- Your newborn makes snorting, snuffling, or squeaking sounds that come and go, especially during sleep
- Your baby is congested during a cold but the congestion clears within 10-14 days
- Congestion improves with saline drops and suctioning
- Your baby is feeding well, gaining weight, and breathing comfortably despite sounding congested
- The congestion is worse in dry environments and improves with a humidifier
- Your baby seems congested all the time, even between colds, and it has persisted for more than 3-4 weeks
- The congestion is affecting your baby's ability to feed comfortably
- Your baby consistently breathes through the mouth instead of the nose
- Your toddler snores loudly every night or seems to have pauses in breathing during sleep
- Your baby is struggling to breathe: fast breathing, flaring nostrils with each breath, retractions (skin pulling in at the ribs or neck), or grunting sounds
- Your baby under 3 months has congestion along with a fever of 100.4F (38C) or higher
- Your baby's congestion is accompanied by thick green or yellow discharge from only one nostril with a foul smell, which could indicate a foreign body or infection

My Baby's Head Shape Looks Abnormal
Many babies develop temporary head shape irregularities that are completely normal. A cone-shaped head from vaginal delivery reshapes within days. Mild positional flattening (plagiocephaly) from sleeping on the back is very common and usually improves with repositioning and tummy time. However, head shape changes involving ridges, a persistently bulging fontanelle, or rapid head growth changes should be evaluated to rule out craniosynostosis.
Achondroplasia (Dwarfism) in Babies
Achondroplasia is the most common form of short-limbed dwarfism, affecting about 1 in 15,000 to 40,000 births. It is caused by a mutation in the FGFR3 gene and is usually apparent at birth with characteristic features including short limbs, a larger head, and a prominent forehead. Intelligence is normal. With monitoring for specific complications and supportive care, children with achondroplasia lead full, active, and independent lives.
Adenoid Hypertrophy and Breathing
Adenoids are lymphoid tissue located behind the nose that help fight infection in young children. When adenoids become enlarged (adenoid hypertrophy), they can block the nasal airway, causing chronic mouth breathing, snoring, nasal speech, and sleep-disordered breathing. Enlarged adenoids are most common between ages 2-7 and are a leading cause of obstructive sleep apnea in young children. Treatment ranges from watchful waiting and nasal steroids to surgical removal (adenoidectomy) if breathing or sleep is significantly affected.
How to Advocate for Your Child's Needs
You know your child better than anyone, and your observations matter. If you feel something is not right with your child's development or health, you have every right to ask questions, request evaluations, and seek second opinions. Advocating for your child is not being difficult - it is being a good parent.
Air Quality and Baby Health
Babies and young children are more vulnerable to air pollution than adults because they breathe faster, their lungs are still developing, and they spend more time close to the ground where some pollutants concentrate. The EPA recommends keeping babies indoors when the Air Quality Index (AQI) exceeds 100 (orange level). During wildfire smoke events, keep windows closed, use air purifiers with HEPA filters, and monitor your child for coughing, wheezing, or difficulty breathing. Long-term exposure to air pollution can affect lung development.
Altitude Sickness in Babies
Babies and toddlers can experience altitude sickness when traveling above 5,000-8,000 feet (1,500-2,500 meters). Symptoms are harder to recognize in infants because they cannot describe how they feel. Watch for unusual fussiness, poor feeding, disrupted sleep, vomiting, and fast breathing. Gradual ascent is the best prevention. Most pediatricians recommend avoiding sleeping at very high altitudes (above 8,000 feet) with infants when possible, and descending immediately if symptoms appear.
