What causes red rashes in a baby's mouth?

Generally, red rashes in a baby's mouth may be caused by local mucosal injury, excessive internal heat ("fire"), oral ulcers, herpangina, or hand-foot-and-mouth disease. If the baby shows any discomfort, parents are advised to seek timely medical attention. Detailed explanations are as follows:

1. Local Mucosal Injury

If parents feed the baby relatively hard foods, such as nuts, jerky, or biscuits, it may irritate the baby's local mucosa, causing bleeding and resulting in red rashes in the mouth. It is recommended to avoid feeding the baby hard foods; instead, crush the food before feeding.

2. Nutritional Deficiency

A deficiency in nutrients such as vitamins B2, B6, B12, iron, or zinc may lead to red rashes appearing in the baby's mouth. Parents can consult a doctor and administer appropriate supplements such as vitamin C tablets or vitamin B2 tablets as directed.

3. Oral Ulcers

Babies may develop oral ulcers due to injuries from biting, overly hard toothbrush bristles, or other irritations, resulting in red rashes in the mouth. Parents are advised to gently rinse the baby's mouth with warm water or saline to reduce pain, and use medications such as Bing Boran Powder or Guilin Watermelon Frost Capsules as appropriate to relieve symptoms.

4. Herpangina

Babies may develop red rashes in the mouth due to an enterovirus infection, which weakens the respiratory tract's protective barrier. This may also be accompanied by symptoms such as sore throat and fever. Parents are advised to follow medical instructions to administer medications such as stomatitis spray or amoxicillin granules to improve symptoms.

5. Hand-Foot-and-Mouth Disease

Babies with relatively weak immune systems are susceptible to infection via airborne droplets or contact, leading to hand-foot-and-mouth disease. Symptoms may include fever and loss of appetite. Under a doctor's guidance, medications such as ribavirin granules or Indigo Naturalis Powder may be used to alleviate symptoms.

Parents are advised to promptly take the baby to see a doctor to identify the cause and provide appropriate treatment. In daily life, pay attention to the baby's diet and appropriately expose the baby to nature, which helps strengthen the baby's immunity.
