Babies with laryngomalacia may exhibit mild, moderate or severe symptoms. The most common sign of laryngomalacia is stridor (loud, squeaky noises that occur when your baby breathes in). Stridor symptoms often worsen over the first several months, but resolve themselves within one year. Even though stridor sounds concerning, most babies with laryngomalacia have no trouble breathing or feeding. In infants with mild laryngomalacia, breathing usually gets louder when lying down, sleeping, crying or feeding. Though not as common, some babies may have severe laryngomalacia symptoms, which include: Loud, noisy breathing. Difficulty swallowing (dysphagia). Apnea (long pauses in breathing). Cyanosis (a condition that causes the skin to develop a bluish hue). Aspiration (pulling food into the lungs). Poor weight gain. GERD (chronic acid reflux). A tugging or “pulling in” at the neck or chest when breathing. If your baby exhibits any of the symptoms listed above, call your healthcare provider right away.
