Glue Ear (Otitis Media with Effusion)

Editorially reviewed | Sources: AAP, NIH|Updated June 2026

The short answer

Glue ear (otitis media with effusion) is a buildup of thick, sticky fluid behind the eardrum without active infection. It is extremely common in young children, affecting about 90% of children at some point before school age. In most cases, it resolves on its own within 3 months. However, persistent glue ear can temporarily reduce hearing and may affect speech and language development if left unaddressed.

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

Glue ear is less commonly diagnosed at this age but can occur, especially after a cold or upper respiratory infection. If your newborn failed their hearing screening, fluid in the middle ear may be a contributing factor. A repeat hearing test is typically recommended at this age before assuming permanent hearing loss.

3-6 months

Babies in this age range may develop glue ear following recurrent colds. Signs can be subtle - your baby may seem less responsive to quiet sounds or voices. If your baby has had repeated ear infections, your pediatrician may check for residual fluid. Most cases resolve spontaneously as the Eustachian tubes mature.

6-12 months

This is a peak age for ear infections and subsequent glue ear. After an acute ear infection resolves, fluid can persist for weeks to months. Your baby may tug at their ears, seem inattentive to sounds, or appear more irritable. If fluid persists for more than 3 months, a formal hearing evaluation is recommended to assess whether it is affecting hearing.

12 months+

Persistent glue ear in toddlers is particularly important to monitor because this is a critical period for speech and language development. If your toddler has had fluid behind the eardrums for more than 3 months with documented hearing loss, your doctor may refer to an ENT specialist to discuss treatment options including ear tubes (tympanostomy tubes). Many toddlers outgrow glue ear as the Eustachian tubes develop.

What Should You Do?

When to take action

Probably normal when...
  • Fluid behind the eardrum is found incidentally during a well-child visit after a recent cold, and your baby seems to hear normally.
  • Your baby had an ear infection and the doctor notes residual fluid at the follow-up visit - this commonly takes 4-6 weeks to clear.
  • Your child has one episode of glue ear that resolves within 3 months without any speech or hearing concerns.
  • Your toddler passes a hearing screen despite having some fluid noted on examination.
Mention at your next visit when...
  • Your baby seems less responsive to sounds or voices than usual, especially after a recent ear infection.
  • Fluid behind the eardrum has been present for more than 3 months based on repeated examinations.
  • Your toddler's speech development seems delayed or they frequently say "what?" or increase the TV volume.
Act now when...
  • Your baby has persistent hearing loss confirmed by audiological testing along with fluid in both ears for more than 3 months - this combination warrants prompt ENT referral.
  • Your toddler is showing significant speech and language delays that may be related to chronic reduced hearing from glue ear.

Trust your instincts. If something feels wrong, reach out to your pediatrician.

Worrying about your baby means you care. That is a good thing.

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.

Are Allergies Linked to Neurodivergence in Children?

Research has found statistical associations between atopic conditions (eczema, food allergies, asthma) and certain neurodevelopmental differences such as ADHD and autism spectrum disorder. However, having allergies does not mean your child will be neurodivergent, and most children with allergies develop typically. These conditions may share some underlying immune and genetic pathways, but one does not cause the other.
