I have a 3 day old. She's currently feeding for about 20-30 mins and is then hungry again half hour later so I'm almost constantly feeding her. My nipples are also cracked and sore even though my midwife has said the latch is good. Is this normal? Everything I've read says my nipples shouldn't be sore and that baby should be feeding 10-15 mins on each side every 2-3 hours...
