ok so my baby has some blood coming out of her little booty. it's not IN her poop but when I wipe her it's on the wipe. I googled it and what I found said to call the doctor but unless she is in pain the ER isn't necessary. I recently started giving her baby food. she eats about one little container every other day. idk if I should be super worried. I plan to call her doctor first thing in the morning but I was wondering if any other mommy has had this with their babies
