It may be possible that you don't have much to pump after feeding your LO. Your supply might have started to regulate and produce just the right amount of milk that your babe needs and not such an overflow like it use to. Hang in there though and keep pumping and putting LO the breast as much as possible to keep supply up. One trick that I did when pumping was to close my eyes and visualize a flowing river of milk, sounds strange but for some reason it seemed to work- good luck
