Young children up to one year of age are most likely to develop pediatric laryngitis, and children of other ages may also develop the disease. On the second or third day of onset, pediatric laryngitis progresses to the later stages. 1. Pre-onset. The baby’s voice is somewhat hoarse and many parents do not pay attention to it and just treat it as an ordinary cough. If parents suspect at this time that their baby may have pediatric laryngitis and treat it promptly, antibiotics may not be necessary. After all, it is not good to use antibiotics when the baby is young. 2. Mid-term. The baby has a fever, but the temperature is not high enough to attract sufficient attention from parents. During the dry cough, there is a “hollow” sound. Some parents feel that the baby’s cough is not normal, and bring it to the hospital, only to know that it is pediatric laryngitis. 3. The face is white or blue or purple. By the second or third day of the illness, pediatric laryngitis makes the laryngeal muscles edematous, blocking oxygen entry and exit channels. The baby lacks sufficient oxygen and reacts with restlessness, does not eat, and has an abnormal face. The baby’s condition can worsen at night. After suffering from pediatric laryngitis, you should let your baby drink plenty of water and not disturb his or her sleep. When treating the disease, try not to use antibiotics if they are not necessary. Follow all the doctor’s orders.
