Ha. I couldn't pump at all. And I tried. And the hospital reeeeally tried (I had a supply like a prize winning Guernsey. My son ate apx 20oz per *feeding* and I could easily add another baby -wetnursed for a friend on two occasions-) but I couldn't pump. Never more than an ounce or two. The hospital sooooooo wanted me to be able to donate! :( Heck. And I'd have really loved not needing to go to class, come home nurse, go BACK to class, come BACK home and nurse. Oy vey. I was putting 150mi a day on my car!
Prob because I was so sensitive to it, I knew a LOT of women who pumped through to not 1 year, but 2 years.
