Red bumps and blisters in babies are most often considered to be caused by viruses or eczema. Pediatric eczema is an allergic skin disease, the main cause of which is intolerance or allergy to food, inhalants or contacts. Mild symptoms can be treated with medication, such as baby eczema cream, pentazocine, and furnace glycine for external rubbing. Baby’s skin should be kept dry and clean, avoid irritation and pay attention to diet. During breastfeeding, the mother’s diet must be light, avoid spicy and stimulating foods, and usually eat more fresh vegetables or fruits, lean meat, etc. Don’t use too hot water to stimulate the child’s skin, keep the skin dry often, and pay attention to the right amount of warmth and cold when wearing clothes, don’t dress the child too thick.
