Noisy breathing in babies (laryngomalacia)

Overview

The soft tissue above the voice box is floppy and falls inward when the baby breathes in, causing a high squeak (stridor).

It's often louder when the baby feeds, cries, or lies on the back.

Usually no treatment.

Self-care

Prevention

To lower your risk or prevent problems:

• There is no known way to prevent it. Early checkups help find it sooner.

Which doctor treats this

• Start with your child's pediatrician.
• They may send you to a pediatric specialist: an ENT doctor (ear, nose, and throat doctor).

Children, pregnancy, and older adults

• Babies under 6 months: Most common.

For caregivers

• Learn the warning signs and when to call the doctor or 911.
• Keep a list of your child's medicines, doses, and doctors on your phone.
• Tell teachers, coaches, and sitters what to watch for and what to do.
• Take breaks and ask for help. Caregivers need care too.

Outlook

Outgrown.

Most babies outgrow it by 12 to 18 months.

Severe cases improve with a small surgery.

Getting ready for your visit
