I have to go back to work part-time when my son is eight weeks. I've already been pumping, but am using it to top up his feedings when needed (he tends to be a lazy eater) and haven't been able to store anything yet. He's still eating every two hours (and would prefer to eat even more often), so the only option is to pump immediately after a feed. The LC and my postpartum doula encouraged me to start storing, but I'm a bit worried about how much of a stash I'll be able to build up in the next few weeks. Just curious how much stored milk others felt was necessary to make the transition reasonably smooth...I'll have flexibility initially to pump as needed at work.
