I started pumping almost as soon as I got home. DH and I are going on a cruise in Feb (DS2 will be 3.5 months) and I knew I'd need a HUGE "stash".... and it's a good thing that I did, because now that I have "regulated"- I can't pump nearly as much as I used to!!!
I currently have about 400 or so ounces saved up... enough for the week we will be gone, PLUS a bunch extra!
