Hello, relax, it has nothing to do with this. Two situations: First, the baby is hot. The suitable temperature is about 20 degrees. Don't cover your baby too much, especially in love sweating. Change your close-fitting clothes frequently and take a bath every day if possible. Add 10g dried Flos Lonicerae, Flos Chrysanthemi, Cortex Phellodendri and Herba Taraxaci in the bath, and wash for three or four days. Second, the skin is allergic. Maybe you used irritating detergent or changed your usual detergent. You can rub Pampers on your baby, take chlorpheniramine orally, once a third, twice a day, and take vitamin C once and a half, twice a day, and it will be fine within three days. If there is no improvement, it is recommended to go to a regular hospital for outpatient examination.
