Could My Baby Have Nasal Allergies (Allergic Rhinitis)?
The short answer
Allergic rhinitis (nasal allergies) can affect babies but is more commonly diagnosed after age 2, when there has been enough allergen exposure. Signs include persistent clear runny nose, sneezing, nasal congestion, eye rubbing or watering, and an "allergic salute" (rubbing the nose upward). Unlike colds, allergic rhinitis does not cause fever and symptoms persist for weeks rather than resolving in 7-10 days.
Parents everywhere have the same worry. You are doing the right thing by looking into it.
By Age
What to expect by age
True allergic rhinitis is very rare in newborns because they have not had enough allergen exposure to develop sensitization. Nasal congestion in this age group is more likely from colds, dry air, irritants, or normal newborn nasal congestion. If your young baby has persistent congestion, discuss with your pediatrician.
Allergic rhinitis remains uncommon at this age. However, some babies with strong family history of allergies may begin to show sensitivity to indoor allergens like dust mites or pet dander. A persistent clear runny nose without fever or cold symptoms may warrant discussion with your pediatrician about potential allergies.
While still uncommon, allergic rhinitis can begin to develop in the second half of the first year. Indoor allergens (dust mites, pet dander, mold) are more common triggers than outdoor allergens at this age. Look for patterns: symptoms that worsen in certain environments or seasons may suggest allergies.
Allergic rhinitis becomes more recognizable at this age. Key differences from a cold include: symptoms last more than 2 weeks, mucus stays clear and watery, no fever, and symptoms may be worse indoors or during specific seasons. Your pediatrician may recommend allergy testing if symptoms are persistent.
This is the age when allergic rhinitis is most commonly first diagnosed. Look for the classic signs: persistent clear nasal discharge, sneezing fits, nasal congestion, dark circles under the eyes ("allergic shiners"), nose rubbing, and mouth breathing. Treatment may include allergen avoidance, saline nasal rinse, and age-appropriate antihistamines prescribed by your doctor.
What Should You Do?
When to take action
- Your baby has a clear runny nose only during colds that resolves within 7-10 days
- Occasional sneezing from environmental irritants like dust or cold air
- Mild nasal congestion that comes and goes without a pattern
- Your baby has persistent clear nasal discharge lasting more than 2 weeks without other cold symptoms
- You notice your baby's symptoms worsen in certain environments or seasons
- Your baby has eczema and/or family history of allergies along with nasal symptoms
- Your baby has severe nasal congestion affecting breathing, feeding, or sleep that does not respond to saline and environmental measures
- Nasal symptoms are accompanied by wheezing, persistent cough, or signs of respiratory distress

Should My Baby Be Tested for Environmental Allergies?
Environmental allergy testing can be performed at any age but is most useful after age 2, when allergen sensitization has had time to develop. Testing may be recommended earlier if your baby has persistent symptoms not explained by infections, family history of allergies, or eczema. Your pediatrician can refer to a pediatric allergist who will determine the most appropriate type of testing.
Seasonal Allergies (Hay Fever) in Baby or Toddler
Seasonal allergies (allergic rhinitis or hay fever) are uncommon before age 2 because children need at least 1-2 seasons of pollen exposure to become sensitized. Most seasonal allergies develop between ages 2-5. Symptoms include sneezing, runny nose with clear discharge, itchy and watery eyes, nasal congestion, and the "allergic salute" (pushing the nose upward with the palm). Unlike a cold, seasonal allergies do not cause fever, and symptoms last as long as pollen exposure continues (weeks to months) rather than resolving in 7-10 days.
Baby Sneezing a Lot - Is It Normal?
Frequent sneezing in babies, especially newborns, is very common and almost always normal. Babies sneeze to clear their tiny nasal passages of mucus, lint, dust, and milk. Since they are obligate nose breathers (they breathe primarily through their nose), keeping those passages clear is important. Newborns may sneeze 10+ times a day, and this is not a sign of a cold or allergies. Sneezing becomes concerning only when accompanied by other symptoms like fever, thick green mucus, difficulty breathing, or poor feeding.
Baby Always Congested (Stuffy Nose)
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.
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.
