Yep, a bad pun.
But it does. It boggles my mind that women choose to pump over nursing. It's hard work. Harder than breastfeeding actually. Give yourself a bit of time, make sure your equipment will let you succeed -- like too many moms try to pump with less than efficient pumps, wrong horns, whatever -- and you will improve.
Get a hands free bra as it will help you have more flexibility while you pump. And I think a computer, iPod, iPhone, smartphone or something like that helps too. Keeps your mind off it.
And don't focus on ounces right not. Just work on getting a routine in place.
