Trying to get freezer stash during a growth spurt?

lizztheo

I just started back at work part time. I thought most of my shifts would be 45 hours, in which case he would only need a few bottles. But I'm on the schedule for an 8 hour shift this week and two the next. I don't have any BM in the freezer! I've just been pumping to the fridge and usually have 3 or 4 bottles in there that get used in a day or two. I really need to get a stash going especially since I'm working more than planned. How should I get that going? Especially now that DS is having a growth spurt and sometimes nursing every hour when I am home.
