I just started back to work yesterday and have already noticed a dip in the amount I'm pumping. Yesterday was ok, I pumped 3 times (10, 1 & 4) and I got about 4 oz each time but today I pumped 4 times (10, 1, 3 & 5) and only got about 2 - 3 oz each time. I also work retail and I'm alone sometimes so I may not be able to keep this schedule all the time. I'm afraid I'm going to lose my supply quick!!!!! Also, I do not have the luxury of pumping for 20 mins or more, I usually wrap up within 10 mind.
