Pediatrician advised me my month old daughter has an underdeveloped trachea. she makes noises when breathing. said she would outgrow. should i be concerned? is there something i should be doing?

Not as long: As she is otherwise normal, she should outgrow it by 18-24 months.

Dr. Is right: What you describe is tracheomalacia. Most children outgrow this by 2 years. It does make breathing noisy. They may have more difficulty breathing if sick with a cold. Positioning the child on their side with the neck slightly extended during sleep is helpful. Tracheomalacia can occur in varying degrees of severity. If it is extreme, sometimes children require a tracheostomy-but uncommon.

Should resolve: Mild tracheomalacia should resolve in time. If your pediatrician is not worried after having evaluated your daughter, i would not be concerned either.

It happens: Babies airways are more rubbery than older kids or adults because they lac the calcium and stiffness that comes with age. Some babies have an ever softer/ flexible voice-box/airway that does create a problem.It sometimes seems to worsen after appearing normal at birth but this is just baby getting more active. Your close monitoring is all that is required .It will pass.
