Babies with tonsillitis can eat fish because it contains protein, while avoiding excessive intake. In addition, multivitamins should be added, and the right amount of water should be supplemented. Because tonsillitis can lead to fever, the breathing will be accelerated when fever is present, and the unobtrusive water loss in the skin will increase, leading to the loss of body fluids, so you should replenish water and multivitamins to promote recovery. When the tonsils are inflamed, you will feel discomfort and pain in the throat, so you should eat a light diet, preferably semi-liquid, easy to digest food, which is conducive to recovery, and pay attention to oral hygiene to prevent the growth of bacteria.
