I've seen and heard a lot similar to you @mynameisntLinda
I was always very surprised at the limited amount of knowledge my local hv clinic had as well in comparison to the bfn group I attended.
I've found It really is the luck of the draw on the knowledge you are able to access and the type of information you receive. Also the support network you have is a huge factor.
I was very, very lucky that one of my best friends is a peer supporter for the BFN and all my family and my husbands family breastfed their children till at least 2.
Also I think being at a midwife led unit helped me as they didn't check any bloods or do any tests etc before we were discharged. All my friends who went to the "big hospital" were told this was wrong, that was wrong, top ups were essential and given some inconsistent advice. If that had been me I would have switched pretty much immediately if I'm honest.
Even my friend who is a nurse was completely befuddled by the whole experience and was given conflicting advice from several sources.
It's not an easy thing to do, whether it goes to plan or not, and each comes with its own sets of pros and cons. It's ultimately down to your own experience and needs and important that you own that decision and not feel any guilt. At the end of the day you'd only be making that decision for the benefit of your children. Nobody can question that 
Having a baby in general is bloody hard work in general anyway without all the other stuff.
@nat2311 that's the view I had. I'd give it a try but wasn't going to beat myself up over it.
Dh is very keen for this one to receive "the same" as dd but different babies have different things and I'm fully prepared for all eventualities. Also it's my body and if I don't want to do it nobody can make that decision bar from me.
For me It's just about taking it one feed at a time and building a support network. My online groups were invaluable to me as well as my irl network.
Groups on Facebook Like Breastfeeding Yummy Mummies and The Breastfeeding Network were great. Happy to send links to anybody who wants them as well.
I wouldn't mind a bit of freedom this time though.
I used to envy my friends who ff would be out with their partners for date nights and all sorts but it did eventually even out (...and then I immediately found out I was pregnant hahah!)
So ill get off my soap box now
and I'm happy to answer any questions anybody has. I'm not peer trained but I spent many many hours of the night trawling the web for the silliest of questions with my first.
