What helped me get this far:
being over 30, confident, stubborn, and having an arsy streak a mile wide, especially when faced with ignorant medics. And more biomedical knowledge than most of them. Plus a Travelcard and public transport obsession, to get to the neearest support.
Hugely supportive partner who told me when I was giving up that he was so impressed with the 5 weeks I'd done so far, especially as my nipples had been so sensitive before birth, and I was bloody fantastic giving A such a good start.
One lovely HV who encouraged me to feed A with him lying on the desk in her office. Not great for my back but wonders for confidence being able to feed him outside the house.
Local midwife-bfcs setting up groups around me. Since A has been born, 3 new ones have been started which is slightly late for me but will help others no end.
Good GP telling me to demand help from all friends and family. While the pain was bad, it was the lack of sleep causing hallucinations that was the main factor in my getting formula out, so someone else could look after A for a few hours while I slept. After a couple days of someone else looking after A in between every feed so I could lie down or sleep, I could cope again.
I'm convinced many women who give up bf do so to get some sleep.
What didn't help:
The myth in every baby book including NHS ones that bf babies on average feed every 3 hours. This might be true by 4 months but not for newborns. I thought I knew everything I could learn from books, but nowhere was it written that newborns often feed hourly and don't sleep in between either! And all of my antenatal class said the same.
Health visitors who have never heard of Baby cafes, breastfeeding support groups, the LLL, etc. In areas like mine where most of them are locums, they should be given sheets with times and contact details of all local support groups.
Lactation consultants and midwife-bfcs and possibly even HVs should have the power to write relevant prescriptions. When you've got thrush/mastitis and a small baby, the last thing you need is to have to fight the phone system the next day to see a GP, even if your GP is clued up on bf and you don't need to argue for the scrip.
More training for HVs - one locally told me they have a 1-year part time course, ie about 6 weeks full-time, which is why they know so little about most things.
Lack of antenatal classes. Luckily I could afford £260 for the NCT and signed up early, otherwise I'd have had none at all, like most women in my area.
Acknowledgement that some formula isn't the end of the world. Almost all the bfers I know ended up giving formula a couple times during a rough patch, but many threads here imply that if you've fallen off the bf wagon and coompromised the 'virgin gut' you might as well not bother bf or that you're unlikely to be able to. It was only giving up bf for a night, under the impression that I'd probably never be able to bf again, that enabled me to be able to bf afterwards. I'm very sceptical that one bottle is likely to corrupt the supply of a struggling mother more than the exhaustion and pain she's already got.
