Quoting Melodys Mommy♡:" Well my breast are hard and hurt. They say that my little one has trouble sucking because she has a small mouth. I try to pump with a manual breast pump but no milk... what should I do??"
Stop pumping. Do not use it to measure.
Put baby on the breast, keep baby there. Babies WILL fuss at the breast, this is normal.
You can express milk by hand, however this WILL cause you to lactate more and will only be a temporary fix for engorgement.
If your nipples hurt: before the latch, express some milk, rub it around on your nipple to lube it up. Squeeze your areola like a cheeseburger.. literally smash it flat, then shove as much as your breast into your baby's mouth as possible.
After baby is done nursing, express a little bit more milk into your nipples, rub it around and let them air dry. Coconut oil feels great on chapped nipples as well.
