have only read op and first few posts, and this has probably been said, BUT...
formula on prescription is - imo - the worst idea i can possibly think of. there are few mothers i know (both in rl and on here) who haven't been given crappy advice by health professionals. in my case it was my hv who told me ds was ready for weaning at 11 weeks because he'd doubled his birth weight. totally bonkers. when i said i was hoping to bf exclusively till 6 months, she looked askance at me and said, "Oh, you're one of those are you?"
now imagine giving her, and people like her, the power to prescribe formula. and that being the only way to get it. even at 2am when your baby is screaming and you have no fricking clue what to do.
bad, bad idea.
FWIW - i think the best way to raise bf-ing rates in this country, is to normalise it. that means that we see less tv programs about how someone bf their 8 year old, or about a 35 year old man who preys on bf-ing women because he gets a sexual thrill from it, and more programs about how lovely a bf-ing experience someone had. or someone who really struggled to bf but managed it in the end. of course this won't happen, because it's normal things like this that don't make the news, but still. i can dream.
also, we need honest antenatal care for new mums. so instead of saying in antenatal classes, "It shouldn't hurt if you're doing it properly, it's a lovely experience, you'll feel so close to your child," and all that stuff, pregnant women hear, "You know what, it might hurt, for a few weeks, even if you are latched on properly. Lansinoh is the best product ever." And, "Breastfeeding can be a lovely nurturing experience, but it might not be." it really fucks me off, the way I was lied to in AN class.
all of this has probably been said further down the thread, and i'm sorry if i'm repeating what others have said. but it is something i feel strongly about. the NHS pays lipservice to the Breast is Best message. i can't remember who said it, but changing that slogan to "Breast is Normal" would be a good start.
