You can read many books about breastfeeding.
You can consult nurses, lactation consultants, and doulas.
You can study pictures that demonstrate correct positions.
You can know that the baby's lips should be "fish lips."
You can remember that her ear and shoulder and hip should be aligned.
You can keep in mind that you should bring the baby to your boob and not your boob to the baby.
You can use an app on your phone to keep track of time of feedings, length of feedings, and which side the baby was on last.
You can be focused and organized and determined, and so freaking happy to have this opportunity at all.
But it is absolutely impossible to communicate to a 5-day-old baby that she should hold off one godforsaken minute to let you make the necessary adjustments on her latch position before she starts sucking away with her superhuman jaw strength and grinding your nipple into hamburger.
