hmm... not sure if the latch on is poor but he manage to empty 1 of my breast last nightMaybe u didn't latch on properly. Cuz initially she only sucked my nipple so not much milk came out. Have to open her mouth wider by pressing her chin downwards to put the whole areola and nipple in, then more milk will come out. After latching I pump to get the remaining milk out cuz too much for her to fully drain the breast though there was once or twice she did empty the breast.
