ftm question so don't make fun of me lol- my daughter is a week old her cord was accidentally pulled out by her clothes pulling it at 3 days old.. she saw her doctor on Tuesday the doctors nurse expressed no concerns but its started bleeding and looks like part of it is still left in her belly button...should I be worried? I plan on calling the nurse tomorrow but I need somebody to ease my mind tonight.
