What is the reason for small red pimples appearing on both sides of a child's mouth?

Patient's question:

Basic Information: Female, 8 months
Disease/Symptoms: Baby has recently developed small red bumps on both sides of the mouth
Description of Condition: My baby is nine months old, and in the past few days, some small red bumps have appeared on both sides of her mouth. What could be the reason?

Doctor's answer:

The symptoms of the infant are considered to be skin eczema. Increasingly more local skin areas are becoming more delicate, with the epidermis of the skin containing moisture and more chlorine, coupled with immature swallowing function and underdeveloped salivary glands. Prolonged irritation. You can appropriately feed loratadine oral liquid. Apply erythromycin ointment externally. Pay attention to maintaining cleanliness and hygiene of the local skin. Daily diet should also be well-conditioned. Maintain a cheerful mood. Wish you good health.
