tiktok - some of the private NCT antenatal classes may well cover things like sore nipples, engorgement, mastitis etc, but i can well remember the NHS antenatal class i attended on bf-ing, when i asked about mastitis, the mw said blithely, "Oh, it's very rare, hardly anyone gets it." on my PN thread, about half of us who were bf-ing (so that's about 10 out of 20 people) had at least one bout of mastitis. so i don't think it's as rare as my mw liked to make out. also, the "If you're latched on properly, it won't hurt" thing. sorry, but that just wasn't the case, for me or for a lot of other mothers i know.
i was very lucky, in that the mw didn't weigh him at all (except for at birth, obviously) and the first time ds was weighed was at 10 days old when the hv had come round and he'd put on over 1lb!
the point i'm trying to make, is that yes, any good bf-ing book or class will tell you "the truth" about bf-ing, but a lot of women don't have access to this. what needs to happen is honest antenatal care, from the NHS across the board, and in all the Trusts. of course, it won't happen, cause of lack of funds, but i can dream!
