When an infant has tonsillitis, attention should be given to their diet. Offer fruits and vegetables rich in vitamins and trace elements, such as pears, watermelons, tangerines, pomegranates, green leafy vegetables, and tomatoes. These foods are light and easy to digest. Additionally, provide soft cooked noodles and congee, which are easy to chew and digest. At the same time, avoid giving infants spicy and irritating foods and drinks, and help them develop good eating habits to prevent picky eating and ensure comprehensive nutrient absorption.
