A baby’s black toe tip may be caused by exposure to cold wind. After hospital warming treatment, it has somewhat subsided, but the swelling has not completely resolved. After peeling, tender skin is exposed, with redness, possibly due to regional edema caused by tight wrapping. It is recommended to consult a doctor again and provide photos for reference. It is still unclear whether it is better to air it out or keep it warm, as the temperature of the baby’s feet at home is low, and it is uncertain whether special warming or sunbathing is needed.
