Failed Newborn Hearing Screening
The short answer
A "refer" or "fail" result on the newborn hearing screening does not necessarily mean your baby has hearing loss. Many babies who do not pass the initial screening have normal hearing on follow-up testing. Common reasons for an initial fail include fluid in the ear canal, vernix debris, or background noise during the test. However, follow-up testing is essential, as early identification and intervention for true hearing loss significantly improves language and developmental outcomes.
This is one of the most common questions parents ask. Searching for answers means you care.
By Age
What to expect by age
0-48 hours
Universal newborn hearing screening is performed before hospital discharge, typically using otoacoustic emissions (OAE) or auditory brainstem response (ABR) testing. The screening is quick, painless, and done while the baby sleeps. If the baby does not pass in one or both ears, a rescreen is usually attempted before discharge. It is common for babies to not pass the initial screen due to fluid or debris in the ear canal from birth, amniotic fluid, or vernix. About 2-10% of babies are referred for follow-up after the initial screening, but only a small fraction of those have permanent hearing loss.
2-4 weeks
If the baby did not pass the in-hospital hearing screening or rescreen, a follow-up appointment with an audiologist should be scheduled within 2-4 weeks. Some hospitals schedule this before you leave. The follow-up test is more comprehensive and is often done in a quieter, more controlled environment. By this age, any birth-related fluid in the ears has usually cleared, making the results more reliable. If the follow-up screen is normal, your baby can be discharged from hearing follow-up. If the baby does not pass again, diagnostic testing will be recommended.
1-3 months
The AAP recommends that diagnostic audiological evaluation be completed by 3 months of age for babies who do not pass the follow-up screening. This typically involves a diagnostic ABR, which measures the brain's response to sound and can determine the type and degree of hearing loss. Early identification is critical because the first months of life are a sensitive period for auditory brain development. While waiting for testing, talk and sing to your baby normally. Even babies with hearing loss benefit from consistent exposure to language and environmental sounds.
3-6 months
If hearing loss is confirmed, the goal is to begin intervention by 6 months of age (the "1-3-6" guideline: screen by 1 month, diagnose by 3 months, intervene by 6 months). Intervention may include hearing aids, enrollment in early intervention programs, speech-language therapy, and in cases of severe to profound hearing loss, evaluation for cochlear implantation. Babies identified and treated early for hearing loss can develop language skills comparable to their hearing peers. Connect with family support organizations and other families who have navigated hearing loss diagnoses.
What Should You Do?
When to take action
- Your baby did not pass the initial screening but passed the follow-up rescreen with an audiologist
- Your baby did not pass in one ear initially due to fluid or debris, and repeat testing was normal
- Your baby passed the hearing screening in both ears and no follow-up is needed
- Your baby startles to loud sounds, quiets to your voice, and shows age-appropriate responses to sound
- Your baby did not pass the hearing screening and you have not yet scheduled follow-up testing
- You have a family history of childhood hearing loss and are concerned about your baby's hearing
- Your baby does not seem to startle to loud sounds, turn toward your voice, or respond to noise by 2-3 months
- Your baby has failed multiple hearing screening attempts and diagnostic testing has not yet been completed, as delay beyond 3 months of age reduces the effectiveness of early intervention and can impact language development
- Your baby had risk factors for hearing loss (NICU stay over 5 days, family history, very low birth weight, or exposure to ototoxic medications) and is not responding to sound as expected at any age, as prompt audiological evaluation is essential

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.
