Unfortunately, bf is not working out with baby #2 either so i've been pumping with the occasional formula supplement. Just curious how long does each pumping session lasts for you, how many times a day and how much do you get per day. My ds is 5 wks today, i usually pump for 20 min, 5 x per day and averaging 750ml (25oz) per day. I'm also on domperidone too.
