Today I have no milk
DD slept for 4 hours on wednesday in the day and has stuffed me up since then. She gets one letdown per side, then wont stay latched on to get the next bit, she pulls off and bites my nipples, and twists her head

My nipples hurt lots now

She wont latch on and do the hard yakka to get the milk out so is not stimulating me enough to produce more. I have been pumping after each feed but cant do anything with the milk as she doesnt take bottles. Im eating lots, drinking plenty, resting and putting her to the breast as often as possible. Any other ideas for boosting supply?
