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. In the past few days, my baby has developed some small red bumps on both sides of the mouth. What could be the reason?

Doctor's answer:

The symptoms of the infant are considered to be skin eczema. More and more local skin is becoming increasingly delicate. The epidermis of the skin contains moisture. More chlorine, plus swallowing function, and the salivary glands are not yet fully developed. Long-term stimulation. You can appropriately feed loratadine oral liquid. Apply erythromycin ointment outside. Pay attention to keeping the local skin clean and hygienic. Daily diet should also be good. Maintain a cheerful mood. Wish you good health.
