My baby is only about two weeks old and he’s also three weeks early. In the hospital he had jaundice and loss to much weight so the staff had me pumping to know his intake. Now he isn’t patient enough to just eat on the breast. So I’ve just continued to pump which is actually working very nicely for us. I’m wanting to know the best way to build up a stock pile. Seems like right now, I’m only able to pump to feed him. I’ve only been able to put three bags in the freezer. I also, would like to know way to increase my supple.
