THe only way i can get my mom to babysit so i can start bartending is if i have bottles pumped. I have a avent isis pump its a small one and i try to pump every morning when i wake up and before she nurses and i get nothing. ever not even a few drops. I try changing the position, pumping faster, pumping slower i try everything i can think of and still nothing. On a rare ocassion if i pump till my nipple is black and bleeding i can get about an ounce I use to be able to pump all the time. My breasts would feel full and i would pump. Now they never feel full I never even leak anymore (yay!) why cant i pump? could i be running out of milk?
