Last time DS didn't latch for a week, even then it was only after pumping (ie. making my nipples stick out more) and the MW said after he was born (and didn't latch) that it was because I have flat nipples. Eventually it was fine, but do I need to prepare them this time round? Last time I found these nipples sucky things for doing it, but it said you have to do it in pregnancy - should I be doing that? Thanks
