Question
A baby who is 5 months and 12 days old, a premature infant, corrected age is 4 months and 10 days, is experiencing a hoarse voice with phlegm, particularly noticeable at night during sleep, causing restless sleep and crying. Although medication has been taken, the effect is not satisfactory.
Answer
For young children without obvious symptoms such as coughing, difficulty breathing, or blue lips, it may be due to underdeveloped laryngeal cartilage. This condition usually does not require special treatment, but calcium supplementation should be noted, as most children can gradually recover to normal by the age of 2 to 3. For older children, if there are obvious symptoms of open-mouth breathing or sleep apnea, it may be caused by enlarged tonsils or adenoids.
