The child’s voice is hoarse due to excessive crying and throat vibration, resulting in congestion and edema of the mucous membranes at the throat. This is the time to soothe the baby and stop crying. Eat a liquid diet. If the child cooperates, you can let the child gargle and rinse the throat with light salt water. You can give your child rice porridge, such as green vegetable porridge, lean meat porridge, and fruit soup made with fruit. If the symptoms are relatively severe, the hoarseness is more pronounced and lasts longer. You can test the blood routine to see if there is an infection of pathogens, combined with nebulized inhalation treatment.
