Where I live (posh part of Edinburgh) BF is absolutely the norm. I felt hugely pressured to BF - to be fair, I really wanted to BF but when the reality set in and I realised that in fact I hated it, I was really torn.
I mean look at me - aged 40, uni graduate, first baby - and FF? WTF?
I fit the BF profile in every way except for actually enjoying it.
Margoandjerry makes a very good point about the 'real cost', ie factoring in the BF mother's time. In my case, it was my time and my mental health.
I hear a lot on here about the support that BF mothers should have. I had all of it - wonderful midwives who let me stay in hospital for 3 days to establish feeding, as many home visits as I asked for, HV visits etc. Not to mention the numerous breastfeeding clinics and cafes run in my area.
Are these services free? To me, they were. But in a wider sense, no of course they're not.
I dunno. I think BF is a wonderful biological function, and I must admit I have a wee smile whenever I see a BF mother. But for something so cheap, easy, natural etc it certainly requires a lot of support.
