Doctor's answer:

Laryngeal cartilage softening, collapse of the laryngeal cartilage during inhalation, causing partial obstruction of the airway and snoring.

The child is affected by neonatal diseases, so parents must take the child to a doctor immediately for treatment to avoid blindly using medication to relieve symptoms. For parents, it is important to observe changes in the child's symptoms and do their best to help the child receive timely treatment for the disease.
