i want so badly to be able to stop pumping and just nurse, but Sawyer gets so frustrated because of his shallow latch and continuously falls asleep at the boob well before he is done, latches and unlatches himself, pushes off the breast, and never empties them like I do when I pump. I've tried almost everything and I'm getting pretty discouraged and frustrated myself. any tips?
