Newborn babies have white stuff on their perineum, which can be gently rinsed with water when bathing the child. This is because the fetus is using the same blood as the mother in the mother’s body, and the mother’s hormone level is higher. After the baby is born, the baby forms its own system, but the hormone level is the same as the mother’s at the time of birth, so the baby’s pubic area will also have white secretions. This is a very normal physiological phenomenon and can be gently rinsed down without any adverse events. When the baby gradually returns to its own hormone levels, the white discharge will not appear.
