Baby's face suddenly develops small bumps, what's the matter?
A 1.5-year-old child has recently developed many small bumps on the face. The bumps are red in color, ranging in size from the tip of a needle to a grain of rice, and are mainly distributed on the cheeks, forehead, and chin. What could this be?

Small bumps that suddenly appear on a baby's face may be caused by various factors. Common causes include infantile eczema, which often results from a baby's delicate and sensitive skin reacting to external irritants, such as certain synthetic fabrics, dust mites, or changes in climate like dryness or humidity. Heat rash could also be a possibility, especially if the baby is overdressed or in a hot environment, leading to impaired skin heat dissipation. Additionally, facial rashes might be due to food allergies, which can occur after introducing new foods that are common allergens.
Closely monitor the progression of the bumps—whether they increase in number, grow larger, or show signs of itching or discharge. Also, pay attention to the baby's recent diet, substances they've come into contact with, and any environmental changes.
Maintain the cleanliness of the baby's face by gently washing with lukewarm water, avoiding harsh soaps or cleansers. After washing, promptly apply a mild baby moisturizer to retain skin moisture and strengthen the skin's protective barrier.
If the bumps persist, worsen, or are accompanied by symptoms such as itching, pain, fever, or other signs of discomfort like rapid breathing or diarrhea, it is important to seek medical attention for the baby promptly.
