Pediatric laryngitis has a rapid onset, sometimes two to three days, and can progress to a life-threatening level for the baby. Therefore, when your baby has the following symptoms, you should seek medical attention immediately without delay. 1. Coughing. Pediatric laryngitis causes a cough at the very beginning of the attack, leaving the baby with a hoarse voice. When coughing, the baby makes a sound like a barking dog. As the condition comes home, the baby’s larynx will also make unusual sounds. In severe cases, the baby’s breathing is not smooth or even difficult. 2. Fever. Most babies have fever after having pediatric laryngitis, but it is rare for babies to have a high body temperature. Because the larynx is partially blocked, the baby does not get enough oxygen. In this case, the baby is irritable and turns white or blue. 3. Flu-like symptoms. Some parents confuse pediatric laryngitis with a cold because the symptoms of both of them are sometimes somewhat similar. Pediatric laryngitis is concentrated in babies under one year old. The onset of the disease tends to be from December of the first year to February of the second year. If your baby develops these conditions, you can be sure to take them seriously. When you have this disease, do not buy your own medicine for your baby, but go to a public hospital for treatment.
