What should a 3-year-old child with mouth ulcers eat?

For a 3-year-old child, oral ulcers may cause pain and discomfort. In terms of diet, it is recommended to provide the child with bland, easily digestible foods such as porridge and soft noodles to reduce irritation to the oral mucosa. At the same time, increasing intake of foods rich in B-complex vitamins and vitamin C, such as fresh vegetable puree and fruit puree (e.g., apple, banana, pear), can help promote healing of the oral mucosa and enhance immunity. In addition, maintaining good oral hygiene is important. You may give the child an appropriate amount of water to drink and avoid food that is too hot or overly irritating. If the oral ulcer persists or worsens, or if the child develops other discomfort symptoms, it is recommended to seek timely medical attention from a qualified healthcare professional.
