For those moms going back to work and still breastfeeding, how did you build your stash when you were still breastfeeding while on leave? I think I'm a little behind the 8 ball on getting my stash ready since I go back to work next Tuesday... but I'm just curious. I'm not sure when I should be pumping. Should I just pump after every feeding? I have some milk frozen, but not very much at all.
