Hi all. My daughter is now 5 weeks old and weighs 10lb 13. She has never successfully breastfed so I have had to express all of her feeds. I am now finding this very tiring and disheartening. I have had all sorts of advice about positioning and timing etc but nothing has worked. She is able to latch on but becomes so frantic that she throws her head back after a few sucks and begins to scream making it impossible to continue. I know my positining is right and I have a really good milk supply. She becomes very frantic when bottle feeding as well (I use a Haberman feeder and her sucking does not seem to be affected when she comes to the nipple)She takes about 5-6 ounces per feed and feeds ever 2.5 - 4 hours. I am on the verge of giving up and am really upset - particularly when my daughter gets so upset. Anyone had a similair experience who can help please?
