Paris never got poo in her vagina, I would wipe out the labia, but never pulling bits open iykwim. When she was little if it was too difficult to manage I would bathe her. And you can still clean real well by not disturbing the top of the labia minora too much. Sorry I just had images of people trying to clean the minora (which can tear easily on a baby especially near the urethral opening) and going a bit crazy.
