If your baby has been diagnosed with or you suspect laryngeal cleft (aspiration during feeding), here is what the evidence says.
The short answer
A laryngeal cleft is a rare congenital abnormality where there is an abnormal opening between the larynx (voice box) and the esophagus (food tube), allowing food and liquid to enter the airway during swallowing. This can cause chronic coughing during feeds, choking, wet or gurgling breathing, and recurrent respiratory infections. Laryngeal clefts are classified into four types based on severity, with Type 1 being the mildest and most common. Diagnosis requires a specialized endoscopic procedure, and treatment ranges from thickening feeds and speech therapy to surgical repair.

“Fever itself is not an illness — rather, it is a sign or symptom that the body is fighting an infection. Fever stimulates certain defenses, such as the white blood cells, which attack and destroy invading bacteria.”
This is one of the most common questions parents ask. Searching for answers means you care.
What Parents Should Know
According to AAP, NIH, Cincinnati Children's guidelines, a laryngeal cleft is a rare congenital abnormality where there is an abnormal opening between the larynx (voice box) and the esophagus (food tube), allowing food and liquid to enter the airway during swallowing. This can cause chronic coughing during feeds, choking, wet or gurgling breathing, and recurrent respiratory infections. Laryngeal clefts are classified into four types based on severity, with Type 1 being the mildest and most common. Diagnosis requires a specialized endoscopic procedure, and treatment ranges from thickening feeds and speech therapy to surgical repair. At 0-3 months, a laryngeal cleft may present in the newborn period with chronic coughing, choking, or color changes during feedings. Babies may have a wet or gurgling voice quality and episodes of desaturation during feeds. Mild clefts (Type 1) can be subtle and easily mistaken for gastroesophageal reflux or a normal swallowing pattern in a newborn. If your baby consistently coughs, chokes, or has breathing difficulty during feeding, your pediatrician may order a modified barium swallow study (MBSS) to check for aspiration. It is generally considered normal when baby occasionally coughs during a feeding but quickly recovers and continues eating without distress. However, you should contact your pediatrician promptly if baby turns blue, becomes limp, or stops breathing during a feeding episode -- call 911.
Normal vs. Concerning
By Age
What to expect by age
0-3 months
A laryngeal cleft may present in the newborn period with chronic coughing, choking, or color changes during feedings. Babies may have a wet or gurgling voice quality and episodes of desaturation during feeds. Mild clefts (Type 1) can be subtle and easily mistaken for gastroesophageal reflux or a normal swallowing pattern in a newborn. If your baby consistently coughs, chokes, or has breathing difficulty during feeding, your pediatrician may order a modified barium swallow study (MBSS) to check for aspiration.
3-6 months
Ongoing aspiration from a laryngeal cleft can lead to recurrent lower respiratory infections, wheezing, and poor weight gain. If a swallow study shows aspiration, your doctor may recommend thickening breast milk or formula to reduce the risk. A pediatric ENT specialist may perform a microlaryngoscopy and bronchoscopy (MLB) under anesthesia to directly visualize and diagnose the cleft. A probe test during the procedure can confirm the diagnosis, as Type 1 clefts are not always obvious on imaging.
6-12 months
For mild (Type 1) laryngeal clefts, management may include thickened feeds, feeding therapy with a speech-language pathologist, and monitoring for respiratory infections. Some mild clefts improve as the child grows and develops better swallowing coordination. For moderate to severe clefts or those not responding to conservative measures, endoscopic injection laryngoplasty (a minimally invasive surgical repair) may be performed. This procedure has a high success rate for Type 1 clefts.
12 months+
As your child transitions to solid foods, aspiration may become less problematic for mild clefts since solids are easier to control than thin liquids. However, drinking water and thin liquids may continue to cause coughing. Your speech therapist can guide safe feeding practices and textures. For clefts that required surgical repair, follow-up endoscopy ensures the repair is intact. More severe clefts (Types 2-4) require open surgical repair and have a more complex recovery course.
What to Tell Your Pediatrician
- Describe when you first noticed laryngeal cleft (aspiration during feeding) and how it has changed over time.
- Note your baby's current age and which age-specific patterns you are seeing.
- Mention if baby consistently coughs, chokes, or gags during every feeding with breast milk, formula, or thin liquids.
- Mention if baby has a wet or gurgling voice quality after feeds.
- Let your doctor know if you have noticed any related concerns, such as changes in feeding, sleep, or movement patterns.
- Bring a list of any questions or observations you want to discuss at the appointment.
What Should You Do?
When to take action
- Baby occasionally coughs during a feeding but quickly recovers and continues eating without distress
- Baby has been evaluated with a swallow study showing no aspiration
- Your baby is feeding well, gaining weight, and has no recurrent respiratory infections
- Baby consistently coughs, chokes, or gags during every feeding with breast milk, formula, or thin liquids
- Baby has a wet or gurgling voice quality after feeds
- Baby has had more than one episode of pneumonia or bronchiolitis in a short period
- Baby is not gaining weight well despite adequate intake
- Baby turns blue, becomes limp, or stops breathing during a feeding episode -- call 911
- Baby has high fever, rapid breathing, and signs of respiratory distress suggesting pneumonia from aspiration
What You Can Do at Home
- Keep track of when you notice laryngeal cleft (aspiration during feeding) — noting the time of day, duration, and any triggers can help your pediatrician.
- Remember that baby occasionally coughs during a feeding but quickly recovers and continues eating without distress — this is generally within the range of normal.
- At 0-3 months, focus on observation rather than intervention unless your pediatrician advises otherwise.
- Follow any care instructions from your pediatrician. Keep a written log of symptoms to bring to appointments.
- While monitoring at home, seek immediate care if baby turns blue, becomes limp, or stops breathing during a feeding episode -- call 911.
Related Conditions
Laryngomalacia (Floppy Airway)
Laryngomalacia is the most common cause of noisy breathing (stridor) in infants. It occurs when the tissue above the vocal cords is unusually soft and floppy, causing it to collapse inward during breathing and create a high-pitched squeaky sound. It typically appears within the first 2 weeks of life, peaks in severity at 4-8 months, and resolves on its own by 12-18 months. Most cases are mild and require no treatment beyond monitoring.
Tracheomalacia in Babies
Tracheomalacia is a condition where the cartilage supporting the trachea (windpipe) is soft and floppy, causing the airway to partially collapse during breathing. This creates noisy breathing, a characteristic "barky" or "honking" cough, and sometimes wheezing. It can be congenital (present from birth) or acquired (often from prolonged intubation in premature babies). Most cases of congenital tracheomalacia improve as the cartilage strengthens with growth, typically by age 2-3.
Stridor (Noisy Breathing) in Babies
Stridor is a high-pitched, squeaky or whistling sound heard when a baby breathes in (and sometimes out). It is caused by narrowing or obstruction of the upper airway. The most common cause in infants is laryngomalacia (a floppy voice box), which is usually harmless and outgrown. However, stridor can also be caused by croup, vocal cord problems, airway malformations, or foreign body aspiration. New-onset stridor or stridor with breathing difficulty always needs medical evaluation.

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.
