This is a spinoff of @MaisyMay's thread (http://boards.hellobee.com/topic/freezer-stash-2) and I didn't want to just hijack it with my question.

For you moms that went back (or are going back) to work (especially those that only have 12 weeks or less maternity leave), when did you start pumping and how much of a freezer stash did you have when you went back to work?
