I have an issue. I have big breasts with flat nipples and a nipple shield/shell doesn't work. My son refused to latch at birth and still refuses to latch. I pump every four hours for an hour with a double breast pump. I am not producing as much as I need too and because of it my child has formula though the day and breast milk at 3am and 9pm....What can I do to help stimulate my milk production? My husband helps massage and everything like that but it doesn't really help!!!
