Your newborn girl's genitals have been exposed to many hormones in the uterus. Among other things, these hormones may have:

Made the outside of the vagina ("labia majora" and the "clitoris") a little swollen and prominent

Caused a thick, milky discharge in the vagina

Most dramatically, at 2 or 3 days of age, your daughter may have a little bit of bleeding from her vagina. This is perfectly normal; it is caused by the withdrawal of the hormones she was exposed to in the womb. It will be her first and last menstrual period for another decade or so.
