Just an FYI that I wish someone had told me when I was pregnant with a girl: your newborn *might* have a period shortly after birth. I was warned that her little breasts might be swollen and leak milk (they were and did), but no one mentioned that she could have a 4-day period due to the surge of hormones she gets from mom. Totally freaked me out to see blood in her diaper from her vagina, but the pediatrician assured me it was normal - not unheard of for full-term girl babies.
