I go back to work in just a few days and it seems as though my milk supply has went down. I've been pumping for about two weeks to get a  stash but I've only gotten enough to for a few days. This week my baby seems to completely empty me and nothing comes out when I pump. I'm worried I won't have enough milk to leave with the babysitter! Any tips to help boost supply and fast. I've added a picture of how much milk I've been getting after a feeding.
